Air Bubbles from all pool jets

Jump to latest Follow Reply
Old valves. Check the O rings in all the suction-side valves, lid and stem O rings. Best is to get new ones and replace them all. Not a lot of expense. Make sure to use pool lube on the stem ones especially.
Don't use a power screwdriver to reinstall the screws. That can crack a new valve and yours are old plastic.
 
MK filter pressure is good about 12 PSI. Jets all appear to have the same output. Yes will buy some new O rings. Thanks for your suggestions.... I did raise the water level but it did not seem to make a difference.
 
Update, the pool tech was out today. He reported that the Jandy pump itself has an internal air leak. He reports he could tell by the sound it was making and it requires a new internal sealent kit....Does that sound reasonable? THe pump is about 15 years old...
 
The shaft seal in a pump is an often-overlooked source of air and when it gets bad enough to cause priming issues will show as water at the bottom of the pump but not always. That's why it is missed so often. Be aware that generic seals for Jandy pumps are sometimes hard to get and OEM are expensive as seals go (like everything Jandy).
 
Thank you MK. I think this maybe beyond our skill set esp when things don't go as planned as usually happens. With such an old pump I'm afraid there may be more things that could go wrong. Will wait and see what the repair estimate is... Will keep this link for future reference.
