Pool Pumps 101:
There are two halves to a pump: one consists of the motor, and the other is the wet end. A specific motor can be compatible with a few different wet ends, so it is important to ensure they are a compatible match. The wet end is where the actual water flows through and also where the impeller and diffuser are located. Aside from the motor and the wet end, there are some smaller parts that make up a pool pump. This includes impellers, o-rings, lids, diffusers, and other hardware.
What’s an Impeller?
How do I know I need a new Impeller?
If your impeller has broken or cracked, you may be able to glue it together, although I don’t recommend it. This would be a temporary fix and is only going to last so long. If your pump does not begin priming (water flowing into the lid of the pump), then you could just need a new o-ring on the lid to be re-lubed and sealed. If your pump does start priming, then something else may be causing the issue.
You could also need a replacement impeller if your pump loses prime and melts your impeller. If you replaced your existing motor with one that has a higher horsepower rating, the impeller may not be the right size, which could lead to the motor overheating and causing the impeller to melt.
More often than not we’re able to find replacement parts without any issues. However, every now and then we will come across a pump that no longer has replacement parts easily available. When this happens, a new pump makes the most sense as we can upgrade to something more energy efficient and also make it easier to find replacement parts in the future.
