    Pentair Quad D. E. Filter Installation

    Seeking advice on installation since I plan to do this myself.
    The filter is a Pentair Quad D.E. 100. Pool is 23,000 vinyl lined Chlorine pool.

    Wanted to know if you guys would suggest adding a multi port valve or sliding valve or no valve at all if I plan to open it up to clean it each time.

    What are your thoughts?
    Thanks

    A multiport valve would give you the ability to backwash when needed in a pinch, and also to drain/vacuum to waste when needed to remove junk or simply lower the water level.

    Rock,

    I agree with only opening and cleaning the filter, but like Pat, I would install a multiport valve just because it gives you the most options.. It would cost a little more, but I think well worth it.

    Oh!! Keep posting, at this point you are up to one post a year...

    The multiport valve gives you the most options. If you ever need to vacuum to waste , leaves, lots of debris, ... Slide valve is simple, but waste lots of DE during cleanups. Hopefully you'll follow TFP recommendations and never have problems.

    I don't backwash my QuadDE 100 and I don't think you will either. I simply tear it down twice a year. I have the simple plunger style backwash valve but could very easily envision myself removing it and not replacing it if it breaks or leaks. Where I live, dry desert, you try NOT to backwash or vacuum to waste as much as possible because water costs money.

    I know of at least one QuadDE guy that purchased the MPV but never installed it. I think it's a waste of money and just one more thing to spring a leak or need fixing.

    Thanks everyone for the advice.

    Yes I don't post much but I can't tell you how much knowledge I have gained from this site or how many times I have shared it over the years.
    This is the only site I trust when it comes to pool anything.

    Thanks so much for everything.

    Oh and since I live on the east coast and from time to time we do get a lot of rain and lowering the pool is a frequent event I plan to install the MPV.

    Tropical storms and just sometimes rain in general seems to come and not stop so for that reason alone I can see the benefits.

    Thanks again.
