I'm hoping someone can help with some of my questions in regards to automation and control valves. To start, my setup. It's a pool/spa combo with a spillover in to the pool. When I moved in (recently purchased) they only had the pool and spa function active on the control system. So if the filter pump was running it was just sucking and returning to the pool with no flow through the spa unless I requested the control system to go to spa. Then it would just suck and return to the spa. This would leave me with the problem of always having to turn on the spa every once in awhile to filter the water in there. Since this time I've enabled the spillover function. This setting defaults the control valves in a position that sucks water from the pool and returns it to the spa.
My question is, is this a problem? Now there's no return in to the pool which I'm guessing doesn't circulate the water as well which may cause me issues. I'm not sure if just the action of sucking the water from the pool creates enough circulation. At least all the water is filtered now though. Any thoughts?
