Pressure Vessel |
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.

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.
