Leak at Pump

[Phillbo]

Hello, I have developed a leak at the connection between my Pentair Whisper Flow pump and the motor. I've checked all the bolt and they are tight.

I get a squirt of water when the motor starts and then a slow drip. Is there an O-ring or a seal between the pump and motor that could be failing?

[SunnyOptimism]

Yes, there are several seals -

lid o-ring
shaft seal
impeller o-ring
diffuser o-ring
seal plate o-ring

Without pulling the pump and doing some disassembly, it's hard to know which seal is going. My first guess would be the shaft seal or seal plate o-ring, but that's only a guess.

Do you feel comfortable pulling the pump and taking it apart?

By the way, how old is your WhisperFlo pump?

[Phillbo]

I'm totally comfortable with pulling the pump and taking it apart. It's the putting it back together part that I'll probably fail at :)

Pump is of unknown age but the motor is 10 years old.
