Pressurizing a pool pump usually refers to "priming" it, which means removing air from the pump and filling it with water so it can properly circulate water from the pool. Here's how to prime a pool pump:
Steps to Prime Your Pool Pump
-
Turn Off the Pump: This is the most crucial safety step. Ensure the pump is completely off before you begin. Disconnecting power is also recommended for added safety.
-
Direct the Water: Ensure the valves are positioned correctly so the pump will draw water from the pool's main drain and/or skimmer. If you have multiple suction lines, start with the main drain.
-
Clean the Pump Basket: Open the pump lid and clean out any debris from the pump basket. A clean basket helps the pump draw water more efficiently. Make sure the basket is properly seated.
-
Fill the Pump with Water: With the pump basket clean and in place, fill the pump housing with water using a hose. Filling the pump with water manually helps create the initial suction.
-
Seal the Lid Tightly: Replace the pump lid and tighten it securely. An airtight seal is essential for proper suction. Ensure the O-ring is clean and lubricated (with a silicone-based lubricant) to create a good seal.
-
Turn on the Pump: Turn the pump on and observe. You should see water flowing into the pump basket.
-
Bleed Air (If Necessary): If the pump doesn't prime within a few minutes, turn it off. There might be air trapped in the system. Many pumps have an air relief valve (usually a small screw or valve on top of the pump housing). Open this valve to release trapped air while the pump is running. Close it when water starts coming out.
-
Repeat if Needed: If the pump still doesn't prime after bleeding air, repeat steps 4-7. It might take a few tries to remove all the air from the system, especially after opening the system for cleaning or repairs.
Troubleshooting Priming Issues
If your pool pump refuses to prime, consider these common issues:
- Leaks: Check all connections (fittings, valves, unions) for leaks. Even small leaks can prevent the pump from creating suction.
- Clogged Lines: A blockage in the skimmer line or main drain can prevent water from reaching the pump. Use a garden hose or plumbing snake to try to clear any obstructions.
- Low Water Level: Ensure the water level in your pool is high enough to cover the skimmer opening. If the water level is too low, the pump will suck in air.
- Worn Impeller or Diffuser: Over time, the impeller (the part that spins to create suction) or the diffuser (the part that directs water flow) can wear down, reducing the pump's ability to prime. These parts may need to be replaced.
Priming your pool pump is a crucial step in maintaining proper pool circulation and filtration. By following these steps and troubleshooting common issues, you can ensure your pump operates efficiently.
