Hi, I just had an inground fiberglass viking pool installed. The installer hooked the plumbing up to my Hayward 24" sand filter and to the 1.1/2 hp hayward super pump. The problem is that there is a gurgling noise near the sand filter up where the elbow pipe meets the filter. It's pretty loud and if the cascade and the jets are both turned on then the psi only registers at 10 and the needle is really jumpy. If I turn off the jets and leave the cascade on high the psi goes up to about 14 but is still pretty jumpy. The gurgling noise is louder when the jets are on then when it's just the cascade. I've done all I can think of to bleed the air out and it's still gurgling. I don't believe I have any leaks in the plumbing because it's only a week old and the pool seems to be filtering fine. I don't even know what the normal psi should be on the gauge at the pump. I feel pretty overwhelmed with the pool now that the installers have left. I just didn't get much info on how to maintain the pool equipment because I didn't buy it directly from the place I bought the pool. I bought it on Amazon. The water is clear and I think it's filtering fine but I just really need some help with understanding what the psi should be and how to get rid of the gurgling noise. Any help would be GREATLY appreciated!! Thanks!!
