    How to rinse?

    Hello All! I'm a newish pool owner and haven't a clue what doing.

    A little background. l replaced my sand last season. At the beginning of this season we had our cool deck redone and I think the debris from the demo is clogging the sand or something. Lots of fine dust comes out of the return jets after a backwash. I've read on here that you should rinse after a backwash but I don't know how. I don't have a multi port valve like the posts I've seen. Here is what I've got. Please ignore the ghetto paint on the filter. Trying to get another season or two out of it. The Arizona sun is brutal.

    Thanks for your help!

    The handle on the plumbing right next to the filter is a push/pull main valve. It has two positions: 1) Normal (filter) and 2) Backwash. Usually the handle has a lock that must be released before moving it (either a button, or twisting the handle, or both). The pump should also be off when switching the main valve.

    If visible dust is getting through the filter, your sand is probably channeled, though there might instead be something broken inside the filter. Try cleaning/resettling the sand bed and see if that solves the problem.

    Welcome to TFP!!!

    You do not have the rinse option. Here is the process for cleaning the sand: Deep Cleaning your Sand Filter

    Thanks for the responses!

    I was just now trying to deep clean the sand. I must be doing it wrong when I try to fill the filter with water its just draining back into the pool. The dirt is washing into the pool through the jets. If I put the backwash valve down into backwash mode it holds the water until it starts flowing out the valve. What am I doing wrong?

    The filter is off. It was just the hose water pressure pushing the dirt through the plumbing.

    Figured it out. I did a search. I'm not the only one that has had this problem.

    Cant find a head slapping emoticon.

    I broke my Jandy valve handle trying to block the flow to the pool so I took it a part and reversed it. And to keep it from flowing out the backwash port I put a bag over the plastic cap inside the filter. The filter is now overflowing filthy water and debris.

    This site is fantastic. Thanks for the help.
