need new filter, may have a pump

[CarlD]

I would not use any pump bigger than 1/2 hp--it's a small pool and more will waste electricity, costing $$$.

What is wrong with your pump/filter? A Hayward 1 hp pump should be repairable--and I hope it's an AG, not IG pump or it will be too strong for your pool.

Give Hayward a call and ask what sand/pump combo they recommend--what matches their 1/2 hp pumps.

In lieu of that, I'd get the T-166 (a little over $200) or T-180 sand filter and a 1/2 hp pump. The filter's capacity will easily be greater than the pump's max, and that means it will filter better. If you can't find a 1/2, a 3/4 up-rated pump will be OK (Full-rated move more water--you don't want that.)

The real experts like Poconos and Waterbear can give you more detailed advice...mine is just rule-of-thumb. But bigger pumps are NOT better--bigger filters are.
