Hayward Sand Filter Drain Thread Type & Size

[PullJunkie]

Hi Everyone, I have a Hayward model S244T sand filter with a drain at the bottom. Can anyone tell me what size and what the thread type is on that drain cap/outlet? I would like to connect a hose to it for when I drain it at the end of the season.

Thanks

I think it’s 1-1/4 inch, you will need to modify something to get it connected to a rubber hose though.

I contacted Hayward and here is the thread size and type: 1" x 11 1/2 NPSM with Higbee start. I just need to find an adapter from NPSM to NPT or any other hose thread.

There is very little residual water in the filter during the closing process. Allowing the water just to trickle out is your best bet. If your pump is indoors, then you can place something underneath to catch the water. I would not tinker around with the drain plug threads. Leave cap off for the winter and you are all set.
