We purchased our home in the summer of 2008. We have an IG pool built about 20 yrs ago. Upon opening pool there was a massive rip in one corner of the vinyl liner. We finally had money this year to fix the liner and start pool up. I did partially winterize the pool each year- air/water blown out of lines and such. Pool specs are:
pool size: 27K gallons, 20x40 (custom L style)
New Emerson 1 hp pump (no idea on flow rate)
The issue we have is that 1) main drain seems to have been cut off at some point (not sure by whom or why). Previous owners never mentioned this as one of the maintenance tasks performed by them. 2) Right skimmer line was repaired and re-piped with spa hose. The hose is not level with skimmer (goes uphill) and was never buried. It is riddled with holes as the bugs really like to eat this I'm told. 3) We closed off the Right skimmer and we are just using our left skimmer, as we were seeing air in the return. Problem is that the air continues. The plumbing for the left skimmer is definitely well underground.
I have tried pouring water over all the suction side joints to see if I see air bubbles. I don't see a difference. I have bled the air from the filter but this only works long enough for the air to fill up again. I tried the red dye test near the skimmer areas and did not see anything pulling. I need to do a definitive evaporation test but am pretty sure we are not losing water. It's been scorching here so I have dropped about 1.5 inches over the past month.
My pool contractor is too busy right now to help with leak detection. He feels the issue is in the underground plumbing. Do you suggest I hire a professional leak detection company before we spend a ton of money on all kinds of plumbing repairs?
