I am redoing my 20yr old hayward pump system with pentair intelliflo VS, intellichlor & a clean & clear 150.
I have two pumps ( pool & spa) with a spa spillover. I want to keep the current single speed spa pump.
This is a simplified version of my plumbing setup:
Any way - I am having my PB do the work. They came out and recommended getting rid of the spa pump and using the pool pump for the spa jets. The PB says it could cause excessive pressure if both pumps are on at the same time. They said if they keep the spa pump then they will not warrantee the plumbing against leaks.Code:Pool Pump---Filter -->-| | to spa return--> | | pool return --< 3waymanual --checkP>---T | | ^checkS | spa pump | spa drain
I don't like losing the spa pump because then I lose control of the spa pump from the air switch next to the spa. Also, I don't want to have to invest in an automation system (intelli-touch...).
I think my system is ok because the check valve between the pool pump and spa pump (checkP in the diagram) will shut when the spa pump is running and all will be well. This should always be the case because the spa pump is fixed speed 3400rms and the intelliflo will be set to have a lower max rpm. Also, I have been using this system with both single speed pumps without problems related to the spa pump for 20 years.
So - the question is - Who's right?
