    leaking filter

    Last week I developed a leak around the filter drain cap. I was also due to change my sand and change my filter valve, so I did. I noted the threads on the filter shell that the drain cap screws onto were damaged and figured that was the source of the leak. I fixed it with some fiberglass marine epoxy. I put the new filter valve on without difficulty, making sure all the gaskets and rings were properly fitted. After cranking everything back up, the drain cap stopped leaking, but now I had a bigger leak of unknown origin. Someone told me it may have something to do with the new valve gaskets. I took the valve off and examined everything closely. Everything seemed to be in order. Then I switched the valve from filter to recirculate and the leaking stopped. Would this lead one to believe it was the new valve? The only other thing I can pin the leak on would be a damaged filter tank, which I cannot see because of the base. I'm not losing a large amount of water, but I've never known of a leak of any kind to get smaller. I would like to hear what some of you community gurus would prescribe as a remedy. Thanks in advance for any help.
    Also I didn't include recent water analysis because it didn't seem pertinent. Was that a breach of etiquette? Hope not. Thanks!

    Re: leaking filter

    "Recirculate" bypasses the filter so it would seem that the leak is probably somewhere at the filter. Sooner or later, you are going to have to figure out a way to follow the path of the water and find out where it's coming from.
