A recent purchase...
I had a repair man come over to look at the problem. Aside from having some debris behind the jets (Plastic and junk from old homeowner neglect), he couldn't find out why the pressure drastically dropped after the spa was filled. He tried to find the air intake for the jets but was unsuccessful and kinda gave up.
We have 4 pipes connected by ball valves coming from the ground that 3 separate pool companies couldn't figure out. They all attributed it to some fountain that probably existed in the yard years ago. When I was cleaning the yard after a backwash, I saw bubbles coming from the ball valves. I investigated further and found out that the valves were kinda shoved in there probably to make to piping look presentable. It was the wrong size valve and wasn't even glued into place. When I removed the valves, the pipes immediately began to suck in air and the jets produced enough pressure to rip your skin off when the pump was on high.
Ive attached a photo of the pipes. Now that I know that these are the intakes for the jets, Can I leave it how it is or am I missing something that attaches to it? (I.E. protection from debris or varmints?)
Thanks
