The are air bubbles in the pump window however when it rains the air bubbles go away. (But does keep the pressure @20psi) I am thinking there is a leak in the plumbing somewhere that when it rain it 'stops' the leak. So the best part - most of the plumbing is under the concrete pool deck. So I hoping to get lucky and dig the ~10' to the pool deck and find the leak (I am thinking of just flooding the trench I create to find the leak.
Also if I move the Jandy from Full Skimmer to Full Skimmer/Main Drain (I have 2 skimmers one has the main drain going through it) bubbles appear I am thinking cavitation from lack of head pressure - or I have a leak on both sides)
Also I am not leaking water (at least it doesnt seem so) - The water level doesn't drop - however I will test it using the bucket method when it stops raining this week.
I am thinking of pressure testing the lines is there an air pressure or suction method w/ the jandy valve installed? Yes I should have done it when I has the whole thing apart this spring.
How bad is air in the system - digging up the 40+ feet of pool deck is not going to happen.
