Old Vs New

[Jeff G - PDX]

I have an in-ground Kidney Shaped fiberglass pool. All Sta-Rite filter and pump componets. The Filter and multiport valve have given up the ghost. After being repaired and such, we made the decision to replace the system.

When the pool was put in, all 1.5" PVC ran underground. All of the new equipment is Sta-rite, but all the new is 2". So, I have purchased the following system components.

Filter: Sta-rate [s8S70]Sta-Rite System 3 Sand Filter - 3.4 SF / 68 GPM

Multi Port Valve: Sta Rite [18201-0200]Sta-Rite Multiport Backwash Valve for System 3 DE/Sand Filter

Pump: Sta-Rite [P6E6G-208L]Sta-Rite Max-E-Pro Pool/Spa Pumps - P6 Series - Energy Efficient 2 hp Pump

Pool Size: 9.5" deep(to water line)

Approx. 28000-30000 Gals

Integrated Hottub and Pool

All of these components are inline with the specifications of my pool and what we had before with the exception of one big detail. The original plumbing is all 1.5" and all of the new items above are 2".

Question:

What are the ramifications if I neck down from 2" to 1.5" on this new pump? (Planning to run 2" line from Pump to filter as a side note.)

Are there any ways I can offset these issues?(ie: Take out the return jet directional balls?, Leave the Hottub inputs open? Etc)

Thank you, any assistance will be greatly appreciated.
