I just recently bought a house that came with an abandoned pool with attached spa. The main pump was stolen or otherwise removed. So i have been doing a lot of research on what size pump to use. I assume it originally had a 2 speed pump to accommodate the spa here r the specs of the pool.
15' x 36' pool
-Estimated 14,000 gallons
-3 - 3/8" jets (they appear to me)
-Pool cleaner attachment that has its own 3/4 horse pump
-250lb hayward pro sand filter rated at 52gpm (50psi)
-I assume it has a floor drain also
-Farthest run of piping is 67' (from farthest pool jet to main pump(pump is really only maybe 25' from edge of pool))
-piping is 2" from drain and skimmers to pump
-piping is 1 1/2" return to pool
-4 jets (appear to be 7/16" jets)
-2" piping to jets
-spills over into pool
-pool pump size if i do just a pump for the pool or a 2 speed for both ( i am thinking about doing separate pumps)
-spa pump size if separated
-if i separate them i assume there is no way to isolate the spa so i wont have to constantly heat water and be warming the pool up.(spa only has jets no return?) seems like it would be very inefficient that way.
-is it a good idea to put separate pumps on them so i can run them separately or at the same time(what is everyone's opinion)
-not putting too much pressure on the sand filter
-amount of head on the pump to push 70'
-energy efficiency to keep bills down(not oversizing pumps) and i dont want to pay a ton for variable speed
I have been looking at hayward super pump or hayward Tristar(my current equip is all hayward)
I hope I have covered everything. I personally have 0 pool experience and knowledge just what i have learned from research. Everyone's help is greatly appreciated!
Also i have had to type all of this from my phone so please excuse any mistakes!
