    Intex sand filter drain/backwash fitting size question

    Just curious, on the Intex sand filter pumps, is the drain/backwash outlet the same non standard thread as the pool inlet and outlet fittings?

    Thanks,
    David

    Yes, all the connections on the filter and pump are the same Intex thread.

    Re: Intex sand filter drain/backwash fitting size question

    And so is the actual drain on the bottom edge of the pool. That ain't no standard garden hose connection...... I had to drain some water to get rid of a hi salt issue. I went to connect a garden hose to the drain plug..... no can do.... AArrgh..... I don't want to drain water right next to the pool, so I used the backwash & rinse settings on the sand filter/pump. Now this worked fine for what I was doing, but when it comes time to drain the water down past all the plumbing for winter storage.....

    Best way to drain for winter is to buy a cheap submersible drainpump. Or pump to waste down to outlet level and siphon the last few inches with a hose over the side.

    Thanks for the info! The reason I asked, I'm trying to find a source of the Intex collar nuts, without having to buy hoses, or other accessories, just to scavenge them. I was looking at the drain caps, as a possible source, if the centers were cut out.

    I use a sump pump. It's my backup in case my house sump pump goes out, but I also used it to drain down my in ground pool at my last home, and I use it to drain down my Intex pool for winter storage. I have a long flexible hose attached to it, to direct the water away from my house & pool. Works great! And works quickly!

    I find this observation quite interesting in the evolution of the Intex pool. I bought my pool last year and it has garden hose sized drains on it. I bet a pool with 40mm drains would empty out fairly quickly!
