I have a PAC-FAB Challenger 2HP Frame: Y56Y Pump Housing: Part #: 35-5460 1081 Pool Pump duty mount horizontal with vent holes down It is leaking between the seal plate and the front housing. The water is coming out the top, right around the clamp band. I think I just need a new O-ring, but I suspect I will need to replace other seals if I take the pump apart. What parts will I need to do this job right?

Hi, Wayne. You will be better off getting the Tune Up Kit - GOKIT5 like you did a few years ago.

    I have the same problem now that I did a couple of years ago. The kit does not have the O-ring that seals the pump housing to the strainer basket (i.e. where I have the leak). the kit has everything but that. And I made the same mistake again. I took the pump apart before I looked at the kit closely. I need the square O-ring. Not happy. Mostly with me. Will try to get it locally.

The gasket is not square, so my question is does the longer edge get installed against the front housing or the short? It does not seem to fit 100% tightly with the thinner edge, but also does not seem to fit perfectly the other way either. The one that came off the pump was the square cut one as well, but I am wondering if even that one was the correct one...

Hi, Chris. The short side of this gasket is placed against the volute. It will seal once the two halves compresses the longer side of the gasket.

Does the Gasket housing 35-5329 have a round or square profile. I recently installed a new motor on my Challenger pump and used the Gokit5, but the round gasket in the kit didn't work and I need the square gasket. Thanks

Hi, John. This Housing Gasket - 355329 is squared.

Unscrew the clamp holding both halves of the pump together. Remove the old gasket. Lubricate and install the new gasket. Reattach both halves of the pump and tighten with the clamp.

I have an older Challenger pump with 35-5188 diffuser. I need to find out how to tell whether I need a round o-ring or square o-ring for both the diffuser and the housing. I ordered the GO-KIT5 that contains both round o-rings. The pump has been serviced multiple times by various people and not sure if round is correct versus square….I have found both types in the used parts box. Thanks

Hi John, The Diffuser (35-5188) is used on the Pentair Challenger High Pressure Pumps. The round o-rings not the gaskets are used with the high pressure pumps.

I've just replaced my housing gasket because I had quite a water leak. The new gasket also leaks. Is there one way the gasket should go on? Or is there something else that could be causing the leak? Water is coming out at a pretty good clip.

A  Answered on 10/13/2014 by InyoPools Product Specialist Patrick P.

Have you checked the shaft seal yet? The shaft seal is located behind the impeller and if it leaks it will come from the union where the motor bolts to the pump. Shaft seals depend on the pump model.
