Hi everyone,
I know you’re all just dying with anticipation to know if my
filter’s air leak as been fixed ;). Sad to say, it has not. I
bought a new pump basket housing (the old one was indeed cracked and
leaking. However, I still have air coming out the return. When I
turn the pump off, I can not see any water leaking anywhere so I am
at a total loss as to what to do next. The hoses are brand new and
are not leaking, I have teflon taped every thread and used pool lube
on everything as well. I think my next option is just to remove the
pumb basket like suggest and see if that really does indeed clear up
the problem. Any thoughts or ideas would be great. Thank you!

Ok, Gisela this is where a bit of science comes in. Air molecules and
smaller that water molecules am I correct! Therefore they can fit through
tighter spaces and since the system does not leak when off we can only assume
that air is being drawn into the system by the suction of the pump. So we
are back to looking at the items before the centerline of the pump housing
and this is one reason I suggested getting rid of the basket was to eliminate
the cover and at least one joint. Is the pump strainer basket full of water
when the pump is running? If the water is not all the way up to the top then
air is being pulled in around the strainer basket cover. With the hayward it
is a quarter turn so rhere is no way to tighten it down. More lube, a bigger
oring or getting rid of the housing are all ways to deal with it. Are the
bubbles just little Champaign bubbles or are they large? If they are just
small and the basket housing stays full then do not kill yourself trying to
fix it.

Hi Gisela,
Suction leaks are much harder to find than pressure leaks, and it
seems like they are harder to stop too. If you can see the bubbles
rising in the filter basket, I would concentrate on imersing the
various joints ahead of the filter basket with water, trying to
observe a stop or slowdown in the bubbles. If you can narrow down the
fitting(s) where the problem lies, you’re halfway there. Be careful
to keep water away from the motor though. Once you’ve hopefully found
the problem, the solution can be challenging too. I’ve found that
screw fittings in the large PVC sizes are hard to seal. I prefer a
thick teflon pipe dope over teflon tape. I have heard some people
even use silicone seal for pipe dope. Try to avoid using screw
fittings where you can - opt for glue fittings and compression
fittings. Good Luck!
