    High filter pressure and low jet pressure

    My DE filter seems to be running higher pressure than normal and the jets don't have the normal force. I've tried backwashing and putting in new DE but it doesn't seem to help much. Any ideas? Filter was last cleaned in Feb. Could it just be due for a cleaning? Pump and skimmer baskets are clean.

    Thanks!

    That would be my next step. I'd shut it down and clean it. Then reevaluate things.

    Ditto what 257 says. Just make sure you don't have a discharge valve partially closed somewhere.

    Thanks! I have someone coming out Friday for a cleaning. This is all so new to me so I'm learning on the go. Hopefully that's the reason the pressure is high and the pool inst circulating well. Should I not run my filter until it has been cleaned on Friday?

    Watch them do it and learn. It's a fairly simple process that anyone can do.

    Should I keep my filter off until its been cleaned Friday? Is that too long to keep it off with this heat?

    Re: High filter pressure and low jet pressure

    I was in the same boat as you. I watched some youtube videos and I was able to do it myself and it was my first time. I didnt want to pay 100.00 to someone when I could do it myself. How much higher is the pressure vs when it is fully clean at normal level?

    I would run the filter as much as possible. If you ahve a multiport valve you can set it to recirc. That way you can chlorinate even if the filter isn't working.

    Its at about 30 when its usually around 18-20. I just wanted to make sure it wouldn't hurt the pump or filter to keep running it until the guy can come out. I have an older purex triton FNS plus filter and will have to learn so I can do this myself next time. No telling what kind of shape its in inside based on the previous owner.

    If the cleaning does not work, there could be the possibility of something stuck in the plumbing that is restricing the flow.

    Re: High filter pressure and low jet pressure

    I would try what Bama Rambler said. If you have a multi port valve and are able to recirculate, check the return flow in the water and see if the jets return to a normal flow. If they do then you know it's the filter causing the low flow.
