I set my system up to work on a single pump and used 3-way zone valves to control the flow to my various exchangers. I had an issue with my pool plumbing and had to rework some of hte pipes. I noticed that the exchanger is very hot even though the 3-way valve is supposed to be off to it. Do these leak a little? The pex piping is fairly short, maybe about 6 feet on either side of the exchanger back to the main loop. Could it just be conducting? I am worried about this because the pool plumbing is just standard PVC and it threads into this exchanger. One of the issues is that this adapter started leaking. I was thinking it might be due to thermal change.
When the pool pump is running it keeps it cool, but it only runs part of the day.
Thoughts?
I looked at my data. I think the valve is malfunctioning. Back in November, when the valve was off I would see the temperature on the Hx drop to almost ambient. Sometime about mid November, I start seeing the off temp climbing. Now it is pretty much stuck on it looks. Any idea what fails on these and is it repairable? It is only 1-2 years old.

I've seen the seals in the valves go out. Most likely not losing enough heat to worry about but when I want to be completely sure I put in a manual three way valve also.

I have 3 of these valves in my system. I believe one of the others is leaking too. So 2 out of 3 are bad in about a year. Is this normal? These are not cheap.

I've heard that acidic water will eat the seals out but I have no idea if it is true.

I have not tested my water since I put it in a year ago. I suppose I could test it again.
