We are having a pool/spa with a spillway built, on pump for pool and spa. The spa will have a separate pump for the spa jets. When the pool company plumbed it they put a split safety drain in the spa (as well as the pool but my question is about the spa drain). They also put another line from the bottom of the spa to the equipment pad to be used as a supply(suction) line. Now they plan to plumb the split safety drain as the suction or supply for the spa jet pumps and use the single supply(suction) line for spa re-circulation (plumbed to the pool/spa pump). So, when the pool is set to spa mode the water will be sucked out of the single line on the bottom and then returned via the spa return lines. Then, when the jets are turned on the water for those will be sucked out of the split safety drain and returned via the jets. This seems backwards and unsafe to me.
My question is two fold. One, since the spa will be in spa mode whenever it's being used shouldn't the supply/suction for that come from the split/safety drain so that you have a safety drain and not a single drain in that instance. And two, should the suction supply for pump to the jet's be on another or second split/safety drain?
It seems to me that if you use the split safety drain for spa re-circulation in spa mode then you at least have a safety drain when the jet's aren't on. At the moment the pool builder is telling me it's better to use the split safety drain for the jets because that pump pulls very hard and the other is fine as a single drain. I guess this concerns me because I have 3 daughters and between them and their friends there will be lots of long haired people swimming in this pool.
Any input would be appreciated.
Thanks!
