Upgrading an Intex pool to sand filter....

[waterbear]

Looking at this one http://www.amazon.com/Intex-100-Gall...1389540&sr=1-1

The pump appears to be 1 HP with 100# sand filter. Pool is 15' x 40' x 48" . Is the filter big enough, and is the pump too big?

The pump is most likely max rated and the brake HP is .95 HP. This would be the same as a full rated 1/2 hp with a service factor of 1.9 or a 3/4 hp uprated pump with a service factor of 1.25. These are both the same pump with a brake HP of .95 such as the Pentair superflo pumps, which have these specs in their full rated and uprated models. This means that this Intex is a 1/2 hp pump. However, given Intex "quality" I suspect that it is just barely a 1/2 hp pump!

Are you sure that it is a 100lb sand filter? Most 100 lb filter skid packs come with 3/4 hp full rated or 1 hp uprated pumps so 1/2 hp full rated is usually enough.However, knowing Intex "quality" I would look at the slightly more expensive skid packs from Pentair and Hayward.


FWIW, the Intex unit is a pump, filter and SWG. Not sure if the SWG can be used separately but I don't think so. Intex has discontinued all their SWGs and the new ones they are selling also include a copper ionizer!
