We have a Hayward Power Flow LX pump. At the top of the skimmer lild there are little bubbles going around and a slight leak. We replaced the O ring, put lube on it, and still bubbles. We then put the original O ring on as well and that helped the leak for now, although I know this is wrong and we shouldn't have to have 2 o rings on there.
Any suggestions as to where this leak could be coming from or what we should be checking. We changed the hoses so those are new, they are nice and tightly connected.
Pressure is the same as it always is and it's coming out the return with plenty of force.
