Hi, I accidentally let my left my filter in backwash mode and the pump run dry for a few minutes. After adding water and starting it back up, I could see that the booster pump was spraying water.
I took it to our local pool store and they replaced the seal. I reconnected it and same problem. I read that maybe the impeller was damaged by the heat.
I bought a kit and replaced the seal, the impeller and the o-rings. I reconnected it and same problem.
I don't know what I'm doing wrong. Is the ceramic piece supposed to be flush with the hole it's in. It sticks out a little. I don't want to force it.
I've seen one video suggest putting silicon caulk around the outside of the spring piece before knocking it into the hole. Is that necessary ?
It's 15 years old. Do I need to replace it ?
