After doing a lot of searching here on the site I was still unable to find a simple solution to hooking up a standard backwash hose to my Intex sand filter.
No offense to anyone who has offered some of the solutions, but they we just not to my liking.
That said, I discovered that Intex sells a # 10849 adaptor for only $3.59 that will allow you to make a super clean FACTORY connection to the drain port of your Intex sand filter.
It looks like this:
A standard 1.5" roll-up backwash hose will then attach perfectly with a hose clamp. I then had my hose cut to the exact length needed to reach a nearby garden drain.
The result is a backwash hose that seems like it came right from Intex with a factory screw on connector.
Try it, you'll like it !
