both skimmers are on the pool. the intake valves I assume are from main drains...one for pool and one for spa. the intake valves have pool and spa written on them.
I really don't like to make that kind of recommendation without knowing the existing pump size because it can easily lead to mistakes. If I had a better idea of the plumbing under ground, I would feel more comfortable making a recommendation. I think have a pretty good idea what your plumbing setup consists of and given that, the 1 HP Superflo seems like the right size but there are still some missing pieces. If you want to take a risk with the Superflo that's fine, given the plumbing size, that is the maximum size I would probably recommend anyway and if you are ok with the spa jets as they are, then it will probably be ok. But I would be reluctant to put a bigger pump on that plumbing anyway.xxxmedicxxx said:I should be able to select the right pump based on needs and plumbing without knowing what pump I have...right?

xxxmedicxxx said:what does up rated 1hp?
Pool pumps come in two ratings; full rated and up-rated which is sometimes called max rated. The only real difference between these types of pumps is how the pump is labeled in terms of horse power (HP). Manufactures will sometimes sell identical pumps in full rated and up-rated versions. The full rated version will have a lower HP but a larger service factor (SF) while the up rated version will have a higher HP but a lower SF.
Service factors determine how far over the rated or labeled HP the electric motor can be driven. Most pool pumps today are used at close to full load which is sometimes called braking HP, service factor HP, or operating HP and can be calculated by multiplying the labeled HP by the service factor. So a full rated 1 HP pump with a service factor of 1.5 would have a braking HP of 1.5 and would be identical to an up-rated 1.5 HP with a service factor of 1. Both pumps will have the same pumping capability and provide the same flow rates for a given plumbing system. This is one of the most confusing aspects of pump ratings.
