    Pump noise - what is normal?

    I just finished installing my AG pool and my filter system. Finally got all the leaks out of the pipes and everything is working just fine. Building up stabilizer levels and keeping it chlorinated is working out OK thanks to this forum. Pics of my cool new pool will be forthcoming in a new thread when the grass grows back!

    BTW - I'm a total noob at this... (so don't laugh, I'll hear you)

    My pump makes noise. Not a lot of noise, but noise. It makes the pump with water going through it noise that I expect (not loud at all), but there is a whining noise that isn't loud but you can hear it as much as the pump noise. I don't know if the whining noise is normal. It's a Pentair whisper-Flo 1/2 HP pump. Can someone tell me if this noise is normal or do I need to have it looked at?

    I started my pool up for the first time just a couple of days ago and have a 1 h.p. whisperflo and I can barely hear it running.

    A whining (high pitched) noise is not a good sign. Usually points to a bearing issue. Is there any leaks near the rotating shaft on the pump?

    Nope. No leaks whatsoever. What you said is what I was thinking.

    The only issue I had is that I couldn't get the thing to stop leaking around the outlet unless I cranked the **** out of the pipe going into it. It says not to do that but I really couldn't find another way to make it seal. I used a TON of teflon tape on it too.

    For the future, Teflon works great on the smaller diameter PVC but, generally, any PVC over one inch I would seal with pipe dope.

    I guess it's just more bad pool store advice... ugh!

    Well, I called the Pentair warranty line this morning. I'll keep you updated on how this shakes out.

    Pentair sent a guy out to look at it and he said it sounds normal, quiet actually, so I guess it's just normal. Good for me!
