Last night as we were in the jacuzzi, an end cap from my pool solar heater blew off. The Jandy 3-way valve (CVA 24) was in the position that closed off the water to the solar so I simply put the toggle switch in the center position thinking it would keep water from going to the solar panels and i could continue running the pump for filtration. I found out when I returned home the water flow didn't stop to the roof. It was a very small amount compared to what it would be if the valve were open. It there a way to get the Jandy valve completely off?
