    DE Filter Pressure gauge

    Very new at this...

    I recently completely cleaned out my DE Filter, took it apart, soaked it in Muriatic Acid, etc.

    Set it back up today and filled it with diatomite. My pressure gauge before even turning the pump on was at 5. Assuming my gauge might be a little off? After adding diatomite, I note the pressure at 14. Should I use 14 as my baseline then? If so, when should I regenerate? At 24? Thanks!

    You need to replace the gauge. tftestkits.net sell really nice glycerin filled ones for the same cost as the junk typically found locally.

    Pressure actually just jumped to 17 in the past hour or so. Pool is very dirty, pump hasn't run continuously literally for about 9 months now.

    The gauge is bad.

    You're going to have to judge clogging by the flow out the returns until you get a new gauge. They're not much harder than changing a light bulb. A little plumber's tape and a wrench or pliers will do it.

    Re: DE Filter Pressure gauge

    Well, gauge hit around 19, and water at this point started flowing out around the clamp seal of the filter. Everything seemed to be running fine until that pressure got up there. Water flying out the return to the pool. Any advice there?

    It's dark out there now, so I just shut off the pump for the night. Will tackle it tomorrow!

    Re: DE Filter Pressure gauge

    Well, went and ordered the suggested glycerin gauge 2nd day air, so should hopefully have it by Wednesday. Have the pump going again right now, holding steady at 17. Went and added my Borax and CYA, because I'm anxious to start a SLAM. Hopefully that pressure won't jump up again and start shooting water out the clamp again. Think I might need to open it up and grease the seal if it does? Or bump it?

    Did you put some silicone grease on the seal prior to putting it together? That helps the lid slide on and seat to prevent leaks. You may also need a new seal.
