Pump questions

gnomeloverFebruary 10, 2011

Hi! We are starting our pool build on Tuesday and just had a quick question. We are building a 18 X 30 pool with an 8 foot spa. We are also adding a solar system. There will be 5 jets in the spa. Our builder says we only need a 2 hp pump for this set up. Another contractor had said we would need a booster pump. Who is right? Will the one 2 hp pump be enough for the pool, spa and solar?

Thank you!

Most likely, it would be fine with the 2 HP, maybe even too much pump. What spa jets are you using? How high is the solar and how big an array? What size plumbing?

Any idea on the head (amount of resistance) in your line? Length of the run from the pump to the pool can affect things what pump/how much power you need as well.

I would use a variable speed pump for this application.

A 2hp, and 1.5 is too much for basic pool filtration, a 1hp might be too small for the solar, and spa jets while the variable speed is just right.

Length of run issues can be mitigated with larger piping.
