I spent a $100 on parts for the pump motor, and new PVC fittings without solving the problem. A pool service man quoted me $1800; said I had an underground air leak in my 40 year old copper pipe and the concrete had to be saw cut. If your pump isn't fully priming, read the section on "Leak...

I found the air leak, finally! The 2" threaded male adapter fitting going into the suction side of the pump was the culprit. Somehow, this connection became loose enough to allow air into the pump and preventing it from fully priming. I ran a running hose over the incoming pipes as...

Looks like Multiport is the way to go. Thanks for your help!

I use DE for my filtration. I have a 3/4 HP Whisperflo Filter Pump... My old brass Push-Pull Backwash Valve is broken and I need to replace. Which is easier to install, easier to use and easier to maintain: Push-Pull valves or the Multiport valves. Comments, please?

My 3/4HP Whisperflo (WFE-3) ran dry and I just took the motor off two days ago to inspect. The thermal breakers on these motors will shut down, cool and restart by itself, which imo, is dumb! These pumps are great, powerful and quiet but getting to that impeller can be a pain in the Rear... To...

CLOG makes sense... Since I use a Kreepy the majority of debris gets sucked by this guy. I disconnected the Kreepy suction hose at the skimmer port, shoved a garden hose at full blast but couldn't get motor to prime. Therefore, the clog may be between the skimmer and my filter? Wow, hard...

Here's the problem: I went to clean the strainer basket from my Pentair Whisperflo WFE-3 and observed the following: A. Flow in the strainer basket chamber is very weak and only half full. B. The temperature got so hot inside the chamber that the plastic basket actually melted! Other...

Any response to any of these? Thanks for your help! I've read the section on pump sizing and I realize that using an automatic pool vacuuming device (like the Kreepy) creates significant additional resistant on your pool's filtration demands. I can understand why the mfgs don't discuss this...

I actually started the thread, "MY 3/4 HP WHISPERFLO FILTER PUMP STOPPED PUMPING", today. The motor lost it's prime somehow and got really hot. I'm going to check out the impeller tonight to see if a palm leaf has jammed up the impeller as Mike S suggested. This is actually the reason my...

I've been using a Kreepy Krawly for the several years. It does a decent job but it tends to get stuck in corners way too often. It also tends to stay towards the deep end and not so much in the shallows. I'm having to do one of two things: 1. Either replace my entire filter pump, or 2...

Thanks, Mark, for your reply. I will take the motor apart and have a look-see at the impeller. It's possible that something's jammed the impeller but, at the same time, I can't see how anything large enough could get past the strainer basket to reach it. Won't hurt to look since I got to...

I've got a WFE-3 Whisperflo Filter and Pool Pump (3/4 HP, 3450RPM, R56Y Frame Type)... I went to empty the strainer basket, yesterday, and sadly the basket was melted at the bottom and there was very little flow coming out of the exit port. Somehow, it lost it's prime and eventually damaged...
