Pump / Filter Question

[howdoo]

I have a small, oval aboveground pool (12' x 18' x 4') (~5000 gal.). I also have a sand filter (Hayward S-180 T). What would be an appropriate pump for this size pool and filter? (Both the pump and filter would be located about 5' from the pool).

I guess a related question could also be: Is this an appropriate filter for this pool?

Thanks!

s180 is a 180 lb filter, should be fine for the pool.
I would highly recommend a 1.0 hp two speed pump. the lower speed for regular filtering, the high speed for the vacuum.

Thanks for the reply!

Just a follow-up, a relative of mine has a 1.5 hp pump that he's willing to give to me. Assuming that the pump is OK to use for this pool (I know it's probably too powerful for a pool of this sizel), just to save some bucks, would this be compatible with the S180 filter or would it just blow it out?

Thanks

If the pump is free I would go for it. From what I have seen it should work for you. If I were to by one I could not agree more with Matt.

Best of luck, Dennis

If it's a 1.5 hp Above Ground pump it's probably OK. But if it's an In Ground pump it may well be too strong. That depends on whether it's an "up-rated" or "full-rated" pump. If it's full-rated, you may be able to get a replacement impeller that lowers the output from the pump.

It all comes down to the GPM the pump puts out, and the max GPM the filter can stand. The pump MUST be less than the filter.

Normally, I would suggest a pump no bigger than 1/2 hp for a pool that size. With that filter, a 1/2 hp would give you great filtering as the filter would be under capacity, and sand filters filter much better when they aren't at or near capacity.

HRSDennis may be able to give you better details if you can provide the pump brand and model # . I know the basics, he knows the details.

Good Morning.

The pump is a 1.5hp vortex XL.

The model # is XL-150s

Thanks for all of the responses!

Thanks Carl, you see I am so stuck in above ground mode this time of year I completely forgot about the possibility of it being an inground pump. There is a big difference.

howdoo, Mostly I just hook this stuff up and trouble shoot when they don't run right. If I sold them I would have to know all of this technical stuff like model numbers and what goes with what.

I can however set up a filter system that won't leak when it is full and ready to use. 99% of the time anyway:)

Maybe someone else can jump in and tell us what those model numbers mean.

It's just Greek to me.

Later, Dennis

Yeah, I've been trying to find out info on it and hit snake-eyes. No luck.

[howdoo]

GOT IT! :D

Took some sluething -- The pump is made by Poolco industries.

Here is a link with all of the technical data, etc.: :confused:

Thanks again for your assistance!

[hrsdennis]

It seems to be an above ground pool pump. I think I found info on it here.

Any help?

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.

[hrsdennis]

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.
