Hi. appreciate any help! im new pool owner and doing everyting on my own. I have a leak in the ball valve that runs to the aerator. Ive been attempting to replace the ball valve but findiing it difficult to attach because not alot of room. there is two jandi valves, one to the salt cell and then returning to the pool and other valve splits off and goes one way to the waterfall that has a 2inch pvc and the other reduceds down to a 3/4inch that goes to the aerator. we litterally never use the aerator becuase we have the waterfall. would it be safe to just capp off the 3/4line to the aerator? if not how do i connect the new ball valve with it being such a tight fit?
