After months of investigation and trying to figure out what is going on, I decided to ask for some help on the forum.
Let's start with the setup:
- 12,000 gallons pool + higher spa (spillover)
- 1 3/4HP main pump
- 1 3/4HP booster for waterfalls
Most of the equipment are Hayward
The pool level is going down (between 1 and 2 inches a week) ONLY when the main pump is running. I had a pool company to come out and to test the piping. They told me that all the lines held pressure so I wasted $440. They also dye tested the pool and they found no leak at all. The shell is in good condition and there is no crack.
The neighbors complained that their grass is soaked on the side of my house and I noticed that the front yard is always wet even though it doesn't rain. Also checked the sprinkler system just in case and there is no leak.
I am out of ideas so I am reaching out to you to see if anyone had the same problem.
I hope ya'll can help me !
Thank you in advance !
