Before you can install a new well pressure vessel, you will need to drain and dispose of your broken tank first. If the tank is full of water, first try connecting the boiler drain to a hose and draining the tank away from the home. If this does not work, it’s very likely the burst bladder is obscuring the water inlet. If this is the scenario you are presented with, you will have to drill a hole in the side of the tank to release the stored water. This can be a messy undertaking, however, a tank full of water can weigh well over 500 lbs. If you are unable to haul the tank out of your well house or garage, you will have to resort to puncturing the tank to drain it.
Replacing the vessel is then a matter of finding another tank with pressure settings and drawdown capacity suited for your household’s water demand. If your vessel was destroyed because of short-cycling, ensure your new tank has a drawdown that matches the output of your pump. The tank’s drawdown is the amount of available water between the well pump turning on and off. To find the drawdown, calculate the minimum runtime of the pump (according to the manufacturer) and the flow rate of your pump in gallons per minute. For example, if your pump’s minimum runtime is one minute, and your pump can produce 10 gallons-per-minute, your drawdown is 10 gallons (1 minute runtime x 10 GPM = 15 gallon drawdown). This is the amount of water protecting your pump from turning off and on.
If your well produces more than 1 gallon per minute, you should have a runtime of around a minute and a half. If your tank’s bladder has failed, reassess the drawdown capacity of your vessel and make sure you have a tank that can support your pressure settings and well pump. Keep in mind, the drawdown will change based on the pressure of the tank. A certain tank may give you 11 or 12 gallons of water at a 30/50 pressure setting, but only 9 if the pressure setting is changed to 40/60. You may be fine with a 30-gallon tank, however, in some cases you may need to upgrade to a 60 or 80-gallon pressure vessel.

A pressure vessel is a bladder type pressure storage vessel designed to hold water under pressure. It extends the time the pump is on and off in each cycle due to the pressure switch not tripping so often. This extends pump life, makes less noise, quietens water hammering and cycling and gives a more consistent flow rate. The pressure tank can also be used to moderate the water flow to match your Hot Water Service or air conditioning unit.
What are the benefits of having a pressure vessel?
The addition of the pressure vessel helps to quieten your pump and reduces pump cycling and hammering. When the tap is turned on the excess water which is held in accumulated storage in the pressure tank will be released to the outlet first. This means the pump does not have to turn on until the stored water has first been used. Thus extending pump life, battery life and giving you a smoother quieter operation.
What if I don't have a pressure vessel?
Pumps will work without a pressure vessel, as there are automatic pumps fitted with a constant pressure controller so these pumps start and start on demand. We recommend having a pressure tank particularly when you have a shower or a toilet where the pump is rarely operating at 100%. Without a pressure tank or accumulator tank the strain will be on your pressure switch/controller, which may cause it to fail early at an inconvenient moment.
Can I add a pressure vessel to my current setup?
Pressure tanks can be fitted to new or existing pump systems.
Where do I position the pressure vessel?
Your pressure vessel needs to fitted on the outlet side of the pump before the water heater or outlets. The pressure tank usually sits on top of your pump or side by side with your pump.
Does the pressure tank come pre-charged?
Yes, all our pressure vessels offered come pre-charged from the factory. Your user manual / operators manual will show you the pre-charged rating
Does a pressure tank help with cycling and water hammering?
The addition of the pressure vessel helps reduces pump cycling and hammering. When the tap is turned on the excess water which is held in accumulated storage in the pressure tank will be released to the outlet first. This means the pump does not have to turn on until the stored water has first been used. Thus extending pump life, battery life and giving you a smoother quieter operation.

Whether you have installed a new pressure tank or your old tank is losing air pressure, balancing it properly will prolong the pump life and give you a steady water pressure. All you need to balance your pressure tank is a tire gauge, an air compressor or a bike pump, and a lot of energy! If you need any assistance, Boulder/GNC Water Well is always here to help.Steps to Follow Before Balancing Your Pressure Tank
Before you attempt to balance your pressure tank, make sure that the tank bladder is not burst. Check this by following the below-given instructions:
Raise the Pressure of Your PumpIf your pump is unable to produce more pressure, you can adjust the pressure switch and rebalance the pressure tank to achieve greater pressure. To change the pressure setting, you’ll need a 5/16” hollow-stemmed nut driver, a voltmeter, a tire gauge, and an air compressor or a bike pump.
Both the pressure settings (30/50, 40/60 and so on) and the 20 psi factory preset range (on at 40, off at 60) can be altered. However, we recommend that you don’t change the preset range or raise the pressure over 65 psi on most switches.
The following instructions can be used to raise the pressure of a Square D Pumptrol Model FSG-2, an extremely common switch.
Pressure switch settings are adjustable, and if you are unsatisfied with the pressure settings provided to you by the manufacturer, you can adjust them to better suit your household needs.
Pressure tanks use compressed air to create water pressure. Since wells do not have positive pressure on their own, well tanks a water storage system that also creates pressurized water using air chambers or rubber diaphragms.
Steel well tanks have an air chamber that is separated from the water by a rubber diaphragm. As water flows into the tank, the compressed air bears down on the diaphragm, increasing the pressure within the tank. Composite well tanks have a balloon-shaped air bladder inside the tank which functions in a similar manner. Every well tank is equipped with a pressure switch that actuates the cycling of the pump. When the pressure in the tank reaches the pre-determined cut-off pressure setting, the switch will alert the pump to cease delivering water to the pressure tank.
When you open a kitchen faucet to fill yourself a glass of water or step into a relaxing shower, pressurized water is delivered to the tap or showerhead on demand. The air within the tank propels the water through your home, so you don’t have to deal with poor water flow and low pressure. However, as more and more water exits the tank, the pressure within the tank will start to decrease. When the internal pressure reaches the pre-determined low point (also known as the cut-on point), the pressure gauge senses the drop, alerting the pressure switch that the tank is in need of more water. The switch then kicks the pump back on and recommences water delivery to the tank. This will continue until the tank once again reaches the cut-off point.
Pressure tanks are an integral part of any well system. They ensure that your home always has adequate access to water. However, more importantly, they protect your well pump from short-cycling. Without the presence of a well tank, the pump would turn on and off every time water was demanded. Submersible well pumps are water-cooled. However, if they’re turning on and off frequently, they are generating a lot of electrical current. This will cause heat to build-up within the motor. This additional generation of heat is detrimental to the electric motor. This will ultimately shorten the life cycle of the motor, incurring a premature replacement. Well pumps are costly and complicated to replace, so preventative maintenance on the well pressure tank itself is crucial to preserving your well pump. So, tanks are not only important for maintaining household pressure, they are the buffer between your pump and rapid cycling.

When is it time to replace your hot water tank? It could be right now! Maybe the right time was 2 years ago, or maybe you’re just fine as you are.
There are 5 clear signs your water tank is on its last legs:
Water isn’t as hot as it used to be.It’s likely corrosion on the inside of your tank has deteriorated the dip tube, overloaded the gas valve or coated your electric elements. A shortage of hot water is a clear sign your tank is over the hill.
The heater is leaking, but I can’t find the leak.If your tank is around 10 years old and you can’t find the leak, it’s probably coming from:
The gas pilot won’t stay lit.The problem is most likely your thermocouple or gas valve.
The tip of a properly installed thermocouple should sit around half an inch inside the pilot flame. This generates the energy required to power a tiny electromagnet keeping the pilot valve open.
If the thermocouple is damaged or not sitting properly, the valve won’t have enough power to stay open.
You can check to see if the thermocouple is properly positioned. If it is, you may have a faulty thermocouple. If you replace the thermocouple and the pilot still goes out, your electromagnet may no longer work and you may need a new gas valve or high limit switch.
If your tank is outside the warranty, replacing the gas valve isn’t worth the money.
I can’t release water through the drain valve.You should drain the hot water tank at least once each year to remove sediment.
If you haven’t done this, a layer of sediment can quickly become many layers of sediment, deteriorating the integrity of the bottom of the tank. The sediment acts as a buffer between the flame and the water it’s trying to heat, so the flame has to burn longer, causing damage to the tank.
If your water tank is so full of sediment it doesn’t drain at all when you open the valve, there is no use trying to fix it. Time for a new tank.
The hot side of the tank can’t hold pressure.Modern tanks contain a check valve on the cold inlet side of the water heater to save energy. It prevents hot water from running up the cold inlet waterline when there is a drop in pressure on the cold side.
But new problems come from this.
When water is heated, it expands and has to go somewhere. With the introduction of check valves, expansion is limited. Hot water and cold water tanks can’t really support each other, and you end up with poor pressure on the hot side of the tank.
A simple fix is installing a small expansion tank on the hot side.
If you get short bursts of pressure when you first turn on a hot faucet, or no pressure at all, your check valve is probably stuck. The check valve is a small plastic ball in a short chamber that floats when not under pressure and is pushed out of the way when under pressure.
An old tank can see scale buildup on the check valve, forcing it to stay in one position rather than moving. In this case, the scale buildup is a sign of a tank that is too far gone for repairs.
When you experience these issues, consider upgrading to a tankless water heater. You’ll go without any of these frustrating, potentially costly issues, and you’ll have all the hot water you need whenever you need it.

Whether you are installing a new well or upgrading your current pressure tank, taking the time to calculate the best size of pressure tank for your well will ensure that your pump performance is optimized and sustained for as long as possible. There’s a reason that pressure tanks come in many different sizes, and it has to do with the fact that every situation is unique and demands for water pressure tanks will vary significantly based on your location, depth of well, type of pump, along with the desired usage for your water.
In order to properly evaluate the optimal size of your pressure tank, you want to be sure that the pressure tank requirements of the well are being met, as a different size will drastically alter the performance of the water delivery process. If the well has a smaller capacity, it is going to affect how a pressure tank works, but this also depends on the system requirements for end use. If the water demand needs are high, there are specific pressure tank models that are offered in order to ensure that that the water delivery and output is maximized even with a well or pump that isn’t necessarily designed for high output.
Most pressure tanks are evaluated by their draw-down capacity, which is how much water can be kept in the tank before the pressure is at a point low enough to turn the pump on again. Naturally, the larger the pressure tank is in size, the more water it can hold without re-engaging on the pump. This means that peak system demands will largely depend on usage needs to ensure that your pump, electric motor and pressure tank are not in overdrive to meet your demands. The proper calculation for a pressure tank size is primarily based on the water pump’s GPM (gallon per minute) capacity, which is provided by the manufacturers based on size. With this information in mind, it is easy to check with your pressure tank supplier to ensure that you are selecting one which meets not only your pump performance, but also your operational needs. Properly sizing a water pressure tank ensures that the run time on the water pump is kept at a minimum. A larger pressure tank can often be a good way to extend the life of your pump and electric motor, provided that you have enough space to accommodate a larger tank and where the flooring can hold the additional weight.
We carry pre-pressurized water tanks, like wates pressure vessel supplier in dubai, which are widely considered to be the industry standard, and they have an online calculator to help you determine the proper sizing. Contact us if you have questions about why we stand behind the Well-Rite brand or if you need some advice on selecting the best water tank for your application.
If you’re one of the lucky home owners with a privately-owned well system providing water to your house, there are some things to know about your well pressure tank. Over the years, several different styles of tanks have been introduced and improved upon. It’s possible that you own an outdated model or that your tank is exhibiting the signs of imminent failure. As a water pump repair in dubai, we repair and service well pressure tanks all the time and are always happy to explain to you what kind of tank you have and what could be wrong with it.
What is a Well Pressure Tank?For homeowners without city-regulated water services, a well is necessary in order to get running water in the house. A well pump, either submersible or a jet well pump, is used to deliver the water from the well to the plumbing fixtures inside your home. A well pump is connected to a well pressure tank, which acts as a reservoir to store the water that will be distributed throughout a home. As you might have guessed for the name, the well tank is pressurized with compressed air. This not only plays a role in the overall water pressure you get in your home, but also helps signal the pump when the water level gets too low and it’s time to refill. There are 3 different types of well pressure tanks depending on the type of mechanism they use to control the pressure.
Air-Over-Water Pressure TanksAn air-over-water tank is usually made of galvanized metal with a fairly simple design. It’s often found in older homes and is not as popular today as other types of pressure tanks. As the name suggests, an air-over-water tank consists of a single chamber filled with water and pressurized air—nothing separates the two. The pressurized air pushes on the water, providing the necessary pressure for your home’s faucets. These tanks are generally larger than most modern models, yet have a capacity similar to much smaller tanks. This disparity in size and capacity of the tank may cause the well pump to cycle on and off more frequently, which may lead to premature pump burn-out. The single chamber design of these tanks also makes them prone to becoming water-logged due to air loss trough pin-hole corrosion.
Diaphragm Pressure TanksDiaphragm pressure tanks consist of two separate chambers: one for compressed air and another for water. A rubber diaphragm is permanently attached to the sides of the tank to separate water from air. It rises and falls with the water level. As water is pumped into the tank, the diaphragm is pushed up to the compressed air chamber which then triggers a sensor to shut off the pump. While efficient, these tanks can have problems with the diaphragm coming dislodged from the sides of the tank, causing water to flow into the compressed air chamber and preventing any pressure from building. If this happens, you will experience a drastic decrease in water pressure and your tank will need to be replaced. Some homeowners have also noted issues with the diaphragm folding over itself and causing false readings by the pump, burning out the pump and ruining the tank.
Bladder Pressure TanksSimilar to diaphragm pressure tanks, bladder pressure tanks utilize two separate chambers for compressed air and water. The bladder is sort of a balloon filled with water that expands and contracts, triggering a sensor to activate the pump. Bladders, being self-contained entities, are useful for those worried about a diaphragm dislodging or folding under the pressure of compressed air. A bladder also generally lasts longer than a diaphragm, making your investment over time much more sensible.
Things to Consider For Your Well TankGetting an appropriately sized tank is essential to having constant water pressure throughout your entire home. A small tank will likely cause your pump to cycle on and off more frequently, which could result in premature wear or a need for total replacement. A tank that is too large for your home could cause the water to stagnate and develop an odd taste or other adverse effects. Luckily, we’re here to help you buy and maintain the right well tank for your need.

A brief introduction to water tanks
Water bladder tanks are tanks which have a rubber bladder in them. The bladder is filled with water or filled with air as the case may be but as expected, a water bladder tank will definitely be filled with water. As soon as a toilet or sink knob is turned on, water is pumped from the water tank. When the water and air pressure gets low, the pressure switch’s contact locks. The pressure switch then conveys an electrical current to the water pump which will end up causing the water pump to start and pump water back into the water bladder tank. The length of time it will take for the pressure switch to lock on depends on the size of the water bladder tank. If the water bladder tank is large in size, it will definitely take time for the electrical current from the pressure switch to get to the water pump.
Mechanism of Water Bladder Tanks
When water is used in the home, or a compound generally, water is going to leave the water bladder tank. As water is being dispensed from the tank, the bladder will reduce in size and the water pressure within the tank will drop significantly. It is also important to point out that water bladder tanks contain air. As the water in the tank goes down, the air pressure will go down too. The pressure control switch, normally sited close to the tank, detects the drop in pressure within the tank. When the pressure drops to a certain level, the pressure switch’s contacts swiftly close together. This leads to the water pump getting switched on. The activated water pump then draws water from the well. At this point, the tank is refilled and water and air pressure within the tank is also restored back to normal.
How does the Water Bladder Tank Get Refilled?
As soon as the pressure switch is activated, the water pump which is normally found near the tank or inside the well immediately pulls water from below the ground back into the tank’s bladder. When the water bladder gets filled, water and air pressure goes back to normal levels. When the both of them have gone back to normal, the contacts on the pressure switch are pulled away from each other. With the relaxation of the pressure switch, water will immediately stop getting pumped into the tank. The whole process outlined above is what plays out as soon as water is used in the home.
If you are looking to setup a bladder water tank in your home or factory do your best to ensure that it is purchased from a reputable shop and installed by them, or a licensed plumber. A wrongly installed bladder tank will cost unnecessary money to replace and so it is very important to get it right the first time. It can’t be stressed enough how important it is to buy from trusted dealers. For more info contact Pressure Vessel Supplier in Dubai or Call us at +971 4 252 2966.
