    Pool Draining Pump

    I have about a 25,000 gal inground pool which needs to be drained. Would this type of pump work sufficiently to do the job (I know it may take 1 day+, but just wondering if it would get the job done). Thanks!

    That doesn't look too bad. At 10' of head it'll still pump 20 gpm.

    Re: Pool Draining Pump

    Awesome, thanks...Since I have to repair the plaster once it is empty, I am going to drain all the way. I will test my tap water (fill water) and post the results to get recommendations on chemicals I will need to add right away upon re-filling.

    I would:
    Fill and get the water circulating.
    Get CYA dissolving targeting 30ppm.
    Add 2ppm of FC.
    After an hour, test everything except CYA to determine what else needs adjusting.

    Re: Pool Draining Pump

    So I drained my pool this past weekend and it is now full again. I tested my FC before the drain and it was off the charts high (25 ppm). I guess having 3 tablets in the pool during the winter in AZ is far too many. I ended up draining about 3/4 of the water and refilling. Right now my levels are as follows:

    FC: 4.5
    TA: 100
    CYA: 60
    PH: 7.2-7.5 range

    These all appear to be OK to me, but is there anything anyone would suggest adding? Thanks for all the help!

    Is this a fiberglass wall with a concrete bottom? What is your calcium hardness?

    It is fiberglass both on the sides and bottom. CH is high, 400. Came out of the tap that way.

    You said that you needed to fix the plaster?

    Re: Pool Draining Pump

    Yeah, I was under the impression that it was plaster...but I had a pool repair guy come out to look at, what I thought was plaster damange, only to find out it was a fiberglass pool. Shows exactly how much I know about pools

    Re: Pool Draining Pump

    I'm guessing that it's concrete that was refinished in fiberglass. Just follow the guidelines for fiberglass pools. If you have iron, you could add a sequestrant. Poolschool has lots of good information about proper chemistry.

    I would recommend that you change from using trichlor as your primary source for chlorine
