On the outlet side of the pump is a T-fitting with a swing valve that bleeds some water going to the pool and sends it to the spa. The problem is the swing valve doesn't open reliably, and then no water goes to the spa. The swing valve acts as a check valve for times you have the t-valve set to spa (all water going to spa), so water doesn't go into the pool side of the plumbing.
I looked at the valve, and there is no way to adjust the spring pressure. What are my alternatives?
