- Turn off the circuit breaker and unplug power to the pump. Confirm that the cord is in good condition.
- Close shutoff valve located in discharge piping (ideally it is installed above the check valve).
- (SKIP THIS STEP IF YOU DO NOT HAVE A SHUTOFF VALVE - we’ll test the valve later) Remove the check valve and visually inspect it for damage. Make sure it fully opens and closes.
- Disconnect the sump pump from the discharge pipe and remove it from the basin.
- Make sure the vent hole in the discharge pipe is clear from debris.
- Clean debris from the exterior of the pump (a garden hose may help a lot with this step).
- Check the pump screen for any blockages or debris and clear any obstructions.
- Reconnect the check valve and replace the sump pump back in the basin.
- Restore power by plugging in the power cord and turning on the breaker.
- Test the pump by dumping a bucket of water into the basin. It should turn on and empty the pit until the float switch turns it off.
- (NO SHUTOFF VALVE ONLY) Inspect the check valve. A faulty check valve will allow water to flow back into the pit after the pump shuts off. Cycle the pump and watch the water level to see if it rises and listen for gurgling/water flowing backwards.
- Check the alarm (if present) and pump float(s) to see if they are mounted properly and free from obstructions.
- The cheapest insurance policy is to make sure you have a backup pump on hand.

A check valve is a valve that is used to prevent backflow in a piping system. The pressure of the liquid passing through the pipe will open the valve, while any reversal of flow will close the valve. The check valve will help your water system maintain pressure when the pump shuts off and also prevent backspin, upthrust, and water hammer.
It is recommended that at least one check be installed in all submersible well pump installations. Many well pumps have built-in check valves. Even if a pump does have a built-in check valve, we recommend that a check valve be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply. Although installers have different opinions, in deep wells we recommend that check valves be installed every 200 feet to distribute the weight on each valve.
What type of check valve do I want? Swing type check valves should never be used in a submersible well pump installation. Swing type check valves have a slower reaction time and can cause water hammer. Spring loaded check valves should be used as they close quickly and thus help prevent water hammer. It should be properly sized to meet the pump’s flow and pressure conditions. The check valves pressure rating must exceed the maximum pressure of the pump.
Backspin, upthrust, and water hammer can lead to early pump or motor failure.
Backspin. When the motor stops, water in the drop pipe can flow down the discharge pipe when there is no check valve or a failed check valve. The flow can cause the pump to rotate in the reverse direction. If the pump starts while it is backspinning, it can cause an excessive force that can break the pump shaft, cause impeller damage, or cause bearing damage.
Upthrust. With a failed check valve or no check valve, the pump will start with zero head pressure. When there is low or no pressure the impellers will “float” up and wear on the diffusers above. This repeated wear can cause premature failure of both the pump and the motor.
Water Hammer. A failed or leaking check valve can cause a vacuum in the discharge piping. When the pump starts, water moving at a very high velocity fills the void and strikes the stationary water in the piping above it, causing a hydraulic shock. The shock can split pipes, break joints, or damage the pump and motor.

What is a positive head booster pump?
The best way to remember the key differences between a positive and negative booster pump is to think push or pull.
A positive booster pump pushes the feed of water into your shower.
It does this by relying on gravity to feed the water from your water tank into the pump. This flow kickstarts the impellers which then pump the water to the shower.
This reliance on gravity means that your water tank needs to be at least 3 feet and 3 inches (990mm) above the shower head.
This allows enough room for the water to pick up speed and kick the pump into action.
What is a negative or universal head booster pump?
Negative (Universal) booster pumps work a little differently. Instead of relying on gravity, a negative (universal) booster pump pressurizes everything in the pipe from the pump to the mixer valve ensuring the pump starts each time.
This type of pump is the best choice for when your shower head is at the same level or higher than the cold water storage tank.
These pumps are used in loft conversions, residential flats and home renovations.

1. Sizing Your Irrigation Pump Properly
To determine the correct sprinkler pump size, first you'll to first figure out how many sprinkler heads you have along with their LPM (litres-per-minute) and PSI (pounds-per-square-inch) requirements.
All sprinkler heads are rated at a specific LPM and PSI. Typically, you're going to use sprinkler heads of the same LPM and PSI rating throughout your system. Assuming you're using the same exact sprinkler heads throughout your irrigation system, the PSI will remain the same.
To figure out the total LPM requirement for your system, you'll add up the GPM requirements for all sprinkler heads. If you have 10 heads rated at 4 LPM each, you'll have a system requirement of 40 LPM.
Since each head is rated at 40 PSI, and the PSI stays the same throughout the system, you need to insure that the pump provides that 40 PSI at your total LPM requirements. In this example, it's 40 LPM at 40 PSI.
However, don't oversize your pump too much. Doing so could blow out your sprinkler heads or cause a sporadic and disorganized spray pattern. Size your pump as close to your system's requirements as possible, and you'll be fine.
2. How High Are You Pumping Water?
The amount of lift required to move the water from its source to your pump is another important factor to consider when planning to install a sprinkler pump. The rise in elevation (referred to as "suction head") must be under 25 feet high, but ideally should be no more than 5 feet high.
The suction head limitation will be listed as a spec on each pump, but should never exceed 25 feet at sea level. Determining the suction head requirements of your sprinkler irrigation system may seem intimidating, but it's actually pretty simple. Measure the distance from the surface of the water source straight up until it meets the elevation of your pump.
That's your suction head. It's much easier for a pump to push water out than it is for it to pull water upward, so it's best to install your irrigation pump as close to the water source as possible without risking water-damage to the pump. While it’s easier for the pump to push the water, it still has its head or lift limitations on the discharge side of the pump just like it does on the suction side.
That could be a maximum head lift of 50, 80, 120 feet of more, depending on the pump. The suction and discharge head, when added together, will then be your “Total Head” lift.
3. How Far Are You Pumping Water?
In addition to considering the suction head, you'll also need to consider how far you're pumping the water to reach your sprinkler heads. The distance in which you're pumping the water can affect the water pressure.
Generally, if the distance from your pump to the furthest sprinkler is under 100', the standard 1-1/2" discharge pipe will work. But, if the distance to your furthest sprinkler head is 100'-300', you'll need to go to a 2" discharge pipe instead. If the distance from your irrigation pump to your furthest sprinkler head is 300'-600', you'll need to increase the diameter of your discharge pipe to 2-1/2".
Basically, you need to increase discharge pipe diameter by one size for every 300' of horizontal pumping distance in order to maintain the best possible flow and pressure. This would be the same on the suction side of the pump when running a long distance. A basic friction loss chart will help in determining your pipe type and diameter based on pumping distance and fittings used.
4. Power Requirements
Because these pumps don't run on luck and good intentions, you'll need to be sure you have the correct power supply. That being 240 volt for single phase or 415volt for three phase
If you have no electricity available where you're installing your sprinkler pump, you'll have to choose a petrol-powered pump as an alternative. Depending on your requirements, it may require a high-pressure petrol pump.
5. Priming Method
Most pumps are self-priming, but some will require you to prime the pump by filling the priming port and pump housing with water upon initial installation to force any air out and allow for the impeller to start sucking water. Any air pockets left in the lines or the pump will cause the pump to become air-bound.
An air-bound pump will not operate properly until the air is removed and replaced by water. As long as a check or foot valve is installed on the suction pipe, and you never lose suction, you should not need to re-prime the pump
6. Choosing a Location For Your Sprinkler Pump
Because sprinkler pumps aren't designed for suction head over 25 feet, you want to install them as close to the water source as possible. Irrigation pumps aren't capable of sucking water beyond 25 feet above their water source. If you have to locate your pump higher above the water source, consider a different type of pump.
Also, be sure to protect your pump from the elements. Your sprinkler pump should be located in a cool, dry area where it won't get rained on, but will still have optimal ventilation. The idea here is to keep it dry, keep it out of direct sunlight, and keep it well ventilated so it doesn't overheat or become flooded.

A household water booster pump is simply a pump system that increases water pressure and flow rate in your home. These are small, modern pumping systems that are an easy one-day install and will make a difference every time you need water.
Many of us take the water pressure in our homes for granted. We assume that when we turn on a tap we will get strong pressure with full flow of water. But this isn’t true in every home — and if your house suffers from low water pressure, you’ll definitely notice the difference. Low water pressure means less flow rate at any tap and it affects how long it takes to do anything involving water. This is when you may consider having a domestic household water booster pump installed.
Some of the problems that may call for a water booster pump include:

This is when you may consider having a domestic household water booster pump installed.
Some of the problems that may call for a water booster pump include:
- Takes too long to fill the tub. Low flow rate means that filling the tub can take five to ten minutes or more, even for a shallow bath for an infant. This also affects water temperature, as water has cooled by the time the tub is full.
- No shower pressure. Who wants to shower under a trickle? This is almost always a pressure problem.
- Not getting good laundry results. Laundry machines need to fill with water to do their job. Low flow rate could mean it takes longer to do a load or that the laundry machine doesn’t even do a good job of cleaning and rinsing clothing.
- Hard to water the lawn. The best spray nozzle in the world will not help with low water pressure. If the hose just puts out a trickle, covering even a small flower bed can take twenty minutes. Watering the whole lawn is endless.
- Cannot rinse dishes. Filling the sink will take longer, and holding dishes under running water becomes a chore.
