Can I purchase the base for it?
Paul T on Jul 3, 2020
BEST ANSWER: I tried to find the base too, but could not find it separately. I have a different brand pump. I ended up mounting it to a water heater platform/stand. Probably voided my warranty because I drill some small holes in the base to connect to the stand. There is a big void space underneath the filter tank, so the small bolts stayed out of the wet tank of the filter.

Happy reviewer
We were able to install it ourselves in a few hours using the same hoses and fittings we already had on hand. This filter comes with instructions, plumber's tape, and a water valve which is optional to use. We let this guy run overnight and in the morning our pool looked like it belonged in the showroom!

I run a 1hp pump and it works wonderful with this filter. I never knew keeping a pool clean was such a headache, this filter helps a lot.
