We have a 12,000 gal saltwater inground pool with a pool pilot infloor cleaning system. We live in FL and run the system almost year round. The pool is about 5yrs old. I recently noticed that three of the floor jets and the jets on the steps into the pool were not popping up all the way or not at all. I have had to replace 2 or 3 of the pools heads in the past few years, but not the suspect heads. I proceeded to pull up each of the suspect heads and did witness some expected debris, but was very surprised to see adhesive/glue on the bottom of the head of the three floor jets?? I realized then that the water pressure coming through the pipes to these jets was extremely low to almost non-existant. Same on the jets on the steps. As I reflect back, I am not sure if the suspect heads ever worked...I have replaced the Hayward filter to maximize flow, cleaned every head in the pool and even placed a garden hose in the open pipes to clear any possible remaining debris or "adhesive." Nothing cleared the issue. There is still not enough pressure to pop the heads up (new heads by the way).
I am now thinking the flow was never where it should be. What can I do to correct/remedy this?? While my pool installer is still in business, we have had many issues with their service and would like to avoid them if possible!
Any and all replies greatly appreciated!
