Diverter valves expected to leak a little bit?

Hi,

I recently redid part of my plumbing to add a Jandy diverter valve. The idea was that I could finally vacuum to waste by diverting the water out and shield the filter from it. From the looks of it however, it looks like the valve always leaks a very tiny amount of water. I see a tiny bit of water collecting in the waste pipe. It's really not a lot. After 12hrs, I can see a small amount in the pipe. My pool pressure is relatively low (2psi when cleaned). Is this expected because these valves were never really meant for a complete seal but more of a diversion from one place to another?

Yes, I have often said these valves were not designed to be water tight. And in particular, they should not be used for open-air applications. In addition to not really being water-tight, they also are susceptible to dirt and other particles that will exacerbate the leaking problem.
