Hayward Pump and Sand Filter Issue

[waste]

Welcome to the forum!

Sorry you're having this trouble

My first thought, on reading your story, would be that the wagon wheel A/K/A spider gasket in the multiport was bad.

However, is the water still coming out the backwash port with the new Vari-Flo valve?

Does the impeller turn easily by hand? (if yes, read on - if no, the shaft is seized and we can tell you how to fix that )

I'm having a little trouble figuring this one out, but suspect a clogged impeller - have you been vacuuming a bunch of 'crud' (especially the leafy pollen string type)? Or perhaps a leak from the discharge port on the pump itself (rather than the multiport). Or maybe a seal assembly issue, water would leak from underneath the pump, where the motor meets the housing.

Any chance of giving us a picture of the system/ where the water is leaking (photobucket is how I post pics - but you might be able to do it without their service) We may have a simple terminology issue (you call it "X" and I call it "Y") - if we can get on the same page, I'll most likely be able to help you

Thanks Lisa, I pray all is well with you/ your health and your family!

Could a photobucket link be a 'work-around'? (a link to an outside source to view the pic)

(No! I have no connection to photobucket but, I can use it, despite the fact I'm 'technologically challenged' )

Sorry. Live links aren't allowed either for temporary subscribers.

Reading your post several times I have to agree with Ted in that the multiport valve seems to have a problem. Doesn't explain the new one doing the same thing though. Ted is also questioning the source of the leak if I read it right. Valve or pump. That should be easy to determine. As for the pump not running up to speed, unlikely. These motors will run at a pretty constant RPM and if you load them to the point of slowing them down then they would overheat quickly. Another point, the pump has nothing to do with a leaking multiport.

Hi all. Thanks for the thoughts. To answer Ted's questions:

Yes the leak is still happening with the new valve. It started about 24 hours after install of new valve. When I took pump apart the impeller was able to be moved counter and clockwise albeit slowly and couldn't just be spun. The pump motor also sounds more like it is humming versus the usual sound.

I don't notice water leaking underneath the pump. Maybe from the connection from the pump to filter although it's not a flow leak more of a drip.

I can take photos and email if need be.

Hi again,
Take a look at this thread.

I still don't understand why a new valve would have that problem and really have no further advice at this point. Per that thread you can maybe diagnose the problem further. On the pump rotor not spinning freely......lot of friction somewhere. Only places are the impeller itself with something wrapped around the shaft or the bearings. I assume you broke things down far enough to rule out impeller issues. Bearings would tend to make a grinding noise when they're about to fail. You may want to take the motor apart further to isolate the problem(s). I should also mention that no part of the impeller should touch the pump housing. The clearance between moving parts is small but there should be no physical contact. I could imagine the pump chamber deforming a little due to overheating and causing the impeller to contact its housing but that's grasping at straws so to speak.
