Hi. I have my TFT 1000 test kit and my chemicals are well balanced but I've now developed an unrelated problem. Where the pipes from the multiport valve attach to the DE filter I've developed dripping leaks. I tried retightening them and teflon thread tape but they still leak. Is there supposed to be a gasket or O-ring of sorts here? I think the person that closed the pool last winter loosened them and that may have started the problems.
See attached pic for red arrows pointing at the leaks.
Many thanks for your help - the website is a great resource.
