I think we posted at the same time

The spec says the pump puts out 70gpm. (I know, I know, no feet of head or anything)

But Hayward says the S-180 T has a flow rate of 35gpm.

Seems to me that this is 'WAY too much pump for the filter.

But I could well be wrong.

Yep howdoo, we got in at the same time.

Since this is an area I am trying hard to learn I am not acting as pool pro.

Carl, with those stats on pump and filter would I be right in saying that the water would blow right through the sand without doing much cleaning?

All of the units I pour 200 lbs of sand into every day have either a 1 or a 1.5 HP pump attached to them. That does not seem to much different than 180lbs. Are there other variables in filter design that would establish a flow rate? And do you know, off the top of your head, how the same unit in a 1 HP would match up?

This whole idea of matching pump to filter has really caught my attention. I always thought is was real simple. Pools were just like cars, the more HP the better.

One more thing to consider howdoo, you may be able to find a good used filter that would match your pump. Bargains are out there.

Tired and must sleep, Dennis

I don't know,but the 180 uses 150#, not 180

I have the 210--200# -- and 1hp full-rated and that's ok.
