Re: Spa Level Still Dropping After Replacing All Check Valve
There is check valve on fifth return in lower picture. It is right after the neverlube valve and right next to gravel. The second pump acts as the booster for spa jets and in floor cleaning system.
In the top picture, the far right pipes are suction from spa to spa jets. Next to that is suction from pool to in floor cleaning system which has a second check valve closer to pool. Next to that is suction from spa for filter operations. Next to that is suction from pool (three pipes).
In the bottom picture, the far left pipe is spa return. Next to that are 3 pool returns and 1 spa water feature return (which has a check valve).
So, do I need to look at replacing the neverlub in 4 places (booster pump, main filter pump, filter discharge and booster discharge). Are there ways to trouble shoot which one and what has failed?
