After listening to it again...it's the multivalve. Hopefully, the O-ring will solve it. I looked online and I can't replace the spider gasket. It's all one piece and I have to buy a new multivalve. I'm already buying a new T-cell-15this year. Maybe I can wait till next year, to replace it. I have a hayward s244t sand filter and the multivalve is sp0714T.

one more thing....I can't get my chlorine up. I had a pool place test my water and they said it was fine. another place tested it...said I needed 5lbs of shock. I added 2 big bottles of bleach. I tested myself and its still very low. Do i keep adding bleach? all of my other numbers are good. Except for calcium but i have a vinyl pool.

For a 22,500 pool that has been closed all winter (we had a very warm winter in arkansas). What is the typical number of bleach containers (1.4 gallon containers) do people typical use??? so far, I have used 5 bottles.
