I recently moved in a home with 22000 gallon swimming pool.
A couple of months ago I noticed that one the return lines from the
filter - a mixture of water and air bubbles in into the pool. The
suction was also almost noticable in the skimmers.
Everything pointed to the strainer basket - checked the O-ring, lubed
it - nothing changed.
A specialist told me that I might have a small whole in the pipes
between the skimmers and the pump. In this case - I will have to dug
the lines up - which I would hate to do - as there is concrete above
Also - I am not sure that this is the case - since I do not loose water
and there is also no noticable persistent wetness around the pool.
Is there a way to diagnose this problem. Also - since there is still
some suction - what if I just change the pump and buy a 2 - 2.5 hp one
- and try to leave with the air bubbles ?
Can something in the sand filter be the problem ?
Next thing we are trying is to blow out the skimmer lines. This thing
started costing a lot of money and summer is around the corner - need
a clean pool :)
