Thanks to all the contributors who have made this site a treasure trove of knowledge. It certainly didn't happen overnight, so thanks!!
Like many, I have bought a house that came with a pool. I am just learning and applying some experience with spas.
Also, like others, I am (currently) primarily concerned with my pool pump operating cost. In San Diego, we are paying $0.35/kWhr at the top tier rate.
19.6K gal, plaster, 2 HP A.O. Smith SQ1202 pump, 325 sqft cartridge filter
Needs to be replastered
Needs skimmer to be repair to fix leaking under decking which has led to shift/cracking of decking
Needs refurbished coping
Needs repairs to vacuum (Hayward NaviGator) including fins, shoes, wings... or just a replacement
SWG, new decking, etc
In-ground pool with attached spa:
Controller (COMPOOL CP3000 inside house):
Hayward NaviGator Vacuum:
Equipment area (controller box, pump, heater, filter, valve actuators):
Filter and Heater:
Electrical Controller (Lx3000) which is 240VAC:
The daily routine is to run the pump from 0800 to 1300. That balances out to about $75 per month.
So the question is, do I try to find a replacement pump motor (48Y flange) for a few $100 or do I make a large investment in a multi / variable speed pump. We are blessed to have some cash to make the investment, if necessary.
As for the pump size in HP, we just have the spa (3 jets) and the vacuum with no other features. Certainly open to right-sizing the motor.
The qualified list of pumps for rebates from my electricity service provider is http://www.sdge.com/rebates-finder/p...-motor-rebates.
