Our spa at our beach condo originally had a 1hp blower on the spa but it would always overheat and stop. Management put a 2hp blower on it and now it gets really hot when people are in the spa and blocking the jets. So much that it has discolored the plastic air feed pipe in the pump room. I have searched but can't find a low pressure relief valve for a spa that would open when the back pressure becomes too much and close when the back pressure goes down. Has anyone encountered a similar situation and found a solution for something like this?
