Hi all, I am not a new pool owner but I am new to these forums. I am so glad to have found an online pool resource. As I said, I have had my pool for 12 years now (before that I was my parent's pool boy for years), but I am trying to get the pool going again after a long period of inactivity. My pool was damaged in a storm and sat for a couple of years without being used while I saved to repair it. I have now replaced the liner, the lights, the pump and motor and put new sand in the filter and replaced the control valve and gaskets on top. The filter is a Tagelus TA-60. Now that everything is up and running I have a problem that I have never run across before and maybe someone can shed a little light on what may be causing this. After the pump runs a few minutes it seems to be laboring, the stream of water from the jets is very aerated and it coats everything in the pools with air bubbles. When you shut the pump off it makes a massive sucking noise and water shoots out of the skimmer basket with enough force to actually blow the lid off. When you restart the pump it seems to have lost it's prime and takes a couple of minutes before there is any water flow. I haven't seen any dirt from the jets that would indicate a burst line, my thought is that it is the filter but I really don't know. Any ideas?
