South Texes. Pentair pumps, one for pool/spa and one for water feature, and Pentair valves. 10K pool with attached spa (and spillover between spa and pool).
My problem: The freeze protection is turned on for the pool, spa, water feature, and Polaris cleaner. I am having the common problem of one of the automatic valves that switches between pool and spa getting stuck, resulting in the pool pump sucking the water out of the spa into the pool. I know the issue is the connection to the microswitch in one valve. No amount of fiddling with the connection fixes the issue permanently. I intend to solder the connections to the microswitches when it warms up and I have time to do the job. For now, I turned off the freeze protection for the spa so the valve won't attempt to switch between spa and pool every 15 minutes. I reasoned that because the pump feeds water to the spa (for the spillover) even when it is pool mode, there is no danger of anything having to do with the spa freezing. Do I have this right?
