Hey everyone I am in the process of closing my pool, while draining on backwash mode, when the water got close to the skimmer line I closed the skimmer valve, there then was a significant increase in the amount of bubbles seen through my pump too.
Is there a leak in my return from the main drain?
I have a small drip leak where the water enters the de filter, due to faulty plumbing, but there was no bubbles in my pump top or coming out of the returns this summer.
How worried should I be?
Also can someone pls tell me what this is?
Thanks a bunch!
