Yup, You can always go bigger.

I would not go bigger (as a ballpark guess) than a 3/4hp pump--even a 1/2hp should be enough. It may take longer to turn over your water, but the cost per turnover will be far less.

With the Hayward 210 sand filter (200#) you can run it up to 1hp (full-rated) but it will work better at lower pressures. I have that unit with a 2 speed 1hp full-rated pump and it DEFINITELY filters better on the low speed.

You CAN be OK with a 150# filter, but definitely don't go higher than 3/4hp up-rated--I believe 3/4hp full-rated is too much.

It's VERY important that the pump NOT be rated higher than the filter for gallons per minute. HP in a pump is not as useful as HP in a car engine. Too much can damage your filter and burns a lot of electric.

Do not get talked into a 1 1/2 or 2hp pump--it gets you nothing but a damaged filter and high electric bills.

Those more expert can give you more detailed guidance than I can, but the parameters won't change.

I've got the same question, but I'm wanting to convert from a cartridge filter to a sand filter. I'm being told to use a Hayward 210 or 240 sand filter which I don't have a problem with. My pool is 18 x 36 or so - 14,000 gallons - above ground, also. I have an existing Purex Triton Maxim pump - part number 39908690 with an AO Smith BN35 motor. It is marked "HP 2.0 SPL" but a parts list indicates that the motor is 1 hp.

I also want to go to a 1/2 or 3/4 hp pump/motor, but I'm being told that "above ground" and "standard" pumps are not exactly equivalent - that, say, a standard 3/4 hp pump that would be used on an in ground pool is really equivalent to an above ground pool 1-1/2 hp pump. In other words, the 1-1/2 above ground pump is ideally matched to the 210 or 240 sand filter ...

A couple of pool catalogs that I've gotten in the mail only offer 1-1/2 pumps for that size sand filter on the combo units.

What size pump do I really have, and if it is oversized - what size above ground pump - pentair or hayword - do I need to go to for maximum efficeincy and cost savings? Thanks ....

Wow, you're pushing my knowledge--our mech expert (Poconos) and the pool dealers should be able to help you.

You can also call Hayward. I didn't get a "set", so I called Hayward and found that their t210 (top mount valve) and their SuperPump 1hp 2speed were, they said, a fine combo, even though they aren't paired and you don't get a base. Hasn't been a problem--24" pavers make a fine base--I don't even bolt the pump down. I run it on low most of the time and never have a problem.

So call Hayward, call your pump manufacturer. Ask the folks who make them.

Thanks for the response, Carl. I haven't called any manufacturers yet. In the short term, I'm going with the pump I have now. I incorrectly listed its size above - the motor is 1 1/2 hp.

I was real interested in the two speed pumps, but at least Hayward's are all 230 volt - I've got 115 volt.
