Not sure if this is the right place to post this. Last year I had my nephews over and one of them decided to push down on one of the pop ups. We managed to get the top portion of it out, but till this day, not sure if part of it is still in the pop up system pipes. We figured it should have came out since we ran the system without that pop-up for a day and the pressure should have taken it out. We replaced it 2 days later, and everything seemed fine. After a while, I noticed the pop-ups would never go down anymore. They would still cycle through, but some pressure was always leaving them up which stops them from rotating as they go down. Then I noticed our manifold in the filter system started to crack and would get worse everytime I cleaned the filters. We decided to get a brand new manifold. Once the manifold was installed, it was working great for 3 minutes, suddenly the outlet tube (we have a jandy CL filter system) started leaking which has never happened before. Then the sides of the tank top started to leak. I was sure the manifold would solved the problems, but I guess there is a bigger issues here. Do you think that pop up piece is still in there and causing back pressure somehow. I need opinions before I shell out huge money for someone to come out here.
