I have a pump that is losing prime. I have had a tech out to search for leaks. His recommendation is to add a check valve because the equipment sits higher than the pool. However, we are tight on space and the check valve can not be added without a complete re-pipe. If re-piped and the pump moved further back will cause no room between the pump and wall. I wanted to get your thoughts on this because I feel there has to be another way?
The red dot in the picture is where he would like to add the check valve but there isn't enough pipe run to add it.
