I have an ongoing suction leak that cannot be solved. I now have the 3 way valve siliconed off, and everything else capped off. Either there is an underground leak, or I am chasing my tail. I noticed that when I took the valve apart the other day, water bled out of the pool through the top off it. If I were to dig out my pool equipment space two feet or so and re plumb, install a gate valve for service,so that pump was now below water level and basically gravity fed, would that eliminate my problem? Also make the pump more efficient? It seems to me it would, but I want to hear from an expert.
