Learn how to prime a pool pump to restore water flow to your pool. Some common causes of low or no water in your pump are listed below. To troubleshoot your pump, identify the recirculation valve and impeller. These two components will determine if the pump is primed.
Common troubleshooting points for priming a pool pump
A number of factors can contribute to a pool pump not priming properly. In some cases, this can be as simple as a clogged filter, but it may also be caused by a blocked return line or valve on the return piping. Before you can try to fix this problem, you should check the water pressure gauge on the filter. High pressure is a sign that you should backwash the filter, while low pressure could mean you need to replace the filter media. In other cases, the problem can be caused by a clogged pump impeller.
A pump may also be faulty if it is wired to an incorrect timer or does not have any switches. A timer is an electrical device that is programmed to run at a certain time. Some timers also have a switch or a timer tag that should be placed on the pump. If your pump is not connected to a timer, you may need to check whether it is wired to a light switch.
Signs of low or no water in the pump
If the pressure gauge is reading less than 12 psi, there are several possible causes. First, it could be the filter or skimmer baskets are clogged. You can clear these problems by cleaning them. In the meantime, you can backwash the filter to restore water pressure.
Another reason your pump is not pumping water is a suction-side leak. Unlike other types of leaks, suction-side plumbing utilizes vacuum action to draw air into the voids, keeping the water from spilling. Alternatively, there could be air in the pump basket, causing air bubbles to come out of the return line and buildup in the filter tank. To avoid this, make sure the pump basket lid is securely shut.
Identifying the impeller
Identifying the impeller is a key step in priming your pool pump. The impeller is located behind the pre-pump strainer basket. Once you have removed the cover, you can reach the impeller by pushing the basket out of the way.
If your pump is not priming properly, you should check the impeller for clogging. If it is clogged, it can cause a noise, a surge, or cause your pump motor to burn out. In this situation, you can remove the impeller and clean it. To clean the impeller, you should unscrew the impeller housing and remove any debris that may be lodged inside.
Identifying the recirculation valve
Identifying the recirculation valve on a pool pump can help you determine if it’s broken or in need of repair. First, open the valve to inspect it for blockages. You’ll also want to look for any obstructions in the O-ring, which may prevent the valve from closing fully. You may also notice air bubbles in the water. These can be an indication of a suction side leak in the plumbing system.
Once you identify the problem, you can repair the valve without affecting the plumbing. The next step is to determine the type of valve you need. There are two types of valves available: 2-way and 3-way. A 3-way valve is more efficient.
Cleaning the impeller
If your pool pump is not producing a vacuum, it may be due to a dirty impeller. The pump’s strainer basket can catch most of the debris, but small particles can get past the strainer and become trapped inside the impeller. These particles can include pine needles, flowering tree stamens, grass clippings, and pieces of pool plaster. Using a simple cleaning solution like pool cleaner can free the impeller of small debris.
The impeller is located behind the pre-pump strainer basket. To reach it, remove the cover and unscrew the screws holding the impeller in place. Once you reach the impeller, use your fingers to gently swirl the impeller around. After cleaning the impeller, replace the basket. Then, fill the pump housing with water.
