Depending on the spa and pool sizes, there are probably several options. 2 speed pump is one option but you could also go with separate pumps for the spa and pool which may be better for larger pools. Key parameters for pump decisions are:

Pool Size (gallons)
Spa and number of Jets
Piping size and number of pool to pad runs

As for the water features, I decided against them for my pool. You may be aware of this already but the water features combined with a SWG usually means the pool will continuously have rapidly rising PH levels. Be prepared to have a lot of acid on hand. Mine rises fairly quickly even without the water features (1qt/week in summer). Also, water features will increase evaporation rates so be prepared for a large water bill as well. Water features are great eye candy but they come at a cost.

Sorry, all that stuff was in my main thread under the construction forum. The spec's are:

Pool size - ~20,000
Spa size - 7.5' with 6 jets
Piping size is 2" for pool and 2.5" for spa. I am not sure what you mean by number of runs to the pad but below is the full specs for piping they gave me.

1. PVC Schedule 40
2. CPVC at pump connections
3. Jandy never lube valves
4. Fill line (1) ¾” Sch. 40 Under the Coping w/Valve & Vac Breaker
5. Main drain: Pool - Paramount MDX Main Drain Assembly
6. Spa - Paramount MDX Main Drain Assembly
7. Pool Return inlets: Per Paramount PCC2000
8. Spa Jets: Six (6) w/ Directional Eyeballs
9. Spa/Commons: Two (2) w/ Directional Eyeballs
10. Skimmers: Two (2) Pentair Bermuda w/Equalizer Lines

Note: Standard plumbing package includes 2” direct piping from each skimmer and main drain assembly to the equipment with independent valves. Spas have 2.5” return and suction piping.

Here is a picture of the final layout.



The water features are already a done deal so I will make sure to keep an eye on my PH levels. Let me know what you think. Thanks!
