How To Prime A Well Pump
Video How to use a well pump. Although their applications are very different, well pumps and water pumps are primed in similar ways. pump that brings water to your home drawn from a well, cistern, or other body of water. This can be a shallow well pump, a conversion jet pump, or a deep well (submersible) pump. how to control well pump

Most well pumps are self-priming, that is, they only need to be primed at the time of installation, Assume pumps, pipes, valves and fittings are properly installed. intake manifold and pump housing. By definition, most pumps are self-priming. As long as the check valve or foot valve is installed on the suction line and you never lose suction, you do not need to reconnect the pump.

Why do you need a well pump?
A well pump needs to be primed to create the internal pressure needed to draw water from your well or other water source and pump it to where you need it. Water pumps are generally classified as Sank deep well pump and Do not sink shallow well pump. Submersible well pumps do not need priming after installation because they operate under water in the well.
When a shallow well pump (pictured at right) is primed, water is discharged through the pump and associated piping until every cavity and hose is filled with water. This is what creates the pressure needed to pump water through your well pump system to wherever you need it in your home. in the system, and prevent backflow in your pipes when the pump is off. Check valves and foot valves are extremely important accessories in a well pump system because they prevent water from flowing back into the well.

Do you need to prepare a submersible well pump?
Deep well pumps do not need priming after installation because they work underwater and are always submerged.
Do you need to dig a well more than once?
Self-priming pumps rarely need to be primed more than once, however, there are instances where you may need to reprime your well pump.
For example, if a check valve or foot valve (right image) stops working, water can fall back into the reservoir when the pump is off, resulting in an air pocket being created in the pipe. The next time the well pump turns on, it spits out air as it struggles to draw water up again. If the engine doesn’t fire first, you won’t be able to draw water until it’s primed (full of water) again.
How to use a convertible jet pump
Switchable jet pumps work similarly to shallow well pumps, except they can be used to draw water from wells up to 90+ feet deep by using a so-called efficient suction process. venturi response.
A conversion jet pump usually has 2 pipes: one used to draw water and one used to push water into the steam outlet, which acts as a siphon by pushing water around the pipe and up towards your outlet valve. Using water, pressure, and the power of gravity, a conversion jet pump can draw water from a much deeper well than a shallow well pump. The basic procedure is similar to priming a shallow well pump as detailed above except BOTH the suction line must be filled with water as well as the pump housing.Read: how to repair a well pump
Troubleshooting Primed Well Pump
If your pump is acting abnormally or not drawing water at the pressure or volume you need, the first step is to check and see if the pump is fully primed (full water to the top). Although unlikely, it is possible that a non-submersible well pump could lose its primary function due to other problems.
Common reasons pumps need to be replaced:
- Good vacuum valve needs to be replaced
- malfunctioning check valve(s)
- pipe or fittings leak
- Non-glued fittings allow air or water to leak
- loose connector or lanyard
- broken seal
- blocked pipe
- the well has dried up
- pump is broken
Even the smallest leak in your suction line will wreak havoc on your system. It’s like how trying to suck on a straw with the eye of a needle will drive you crazy. For this reason, we also recommend that you check all threaded fittings for air leaks or at least ensure that plumber’s tape is used on all fittings on the suction side. to help prevent leaks.
How to fix low water pressure
If you have determined that the well pump does not need to be replaced and all of the above have been checked, the next thing to do is check the retainer (pressure). If your well pump does not have a pressure gauge, it may be helpful to install an external pressure gauge at the pump or at the outlet to monitor the water pressure level. changes. For example, if your accumulator is filled until it produces 40 PSI and starts your well pump when it drops below 20 PSI, monitor how often the pressure drops below the threshold to help determine determine when (and where) water pressure is being read: How to Use a Well Pump If you have strong water pressure in some equipment but not others, it may be clogged or reduced in somewhere else in the pipe in your home’s water line. If everything else is working properly, you can use a booster pump to boost the water pressure to your appliances.
