Hey all,
I’ve tried researching and looking for answers but I haven’t been able to. I have a two part question about suction, as well as heating. I’ve never owned a pool before so all of this is completely new to me.
I have a shared pool/spa where the spa spills over into the pool. I currently have the suction set 100% to the pool and the spa return 100%. This is what was recommended to me when I first bought our place by a couple of pool maintenance folks. At this setting the pressure on the filter shows around 20. If I want to heat the pool I change the valve from spa to pool and it seems to work fine.
The problem (and question) arises when I attempt to heat the spa. Since I usually leave the return to spa on 100%, normally I should just change the suction from pool to spa, right? If I do that my pressure goes down to 0 and there’s barely any water coming into the pump. In addition, my heater lights will show “service system” which doesn’t occur when heating the pool. I’ve tried backwashing and it doesn’t change anything. I’m using a brand new 4 speed variable pump, but this issue was also occurring prior to pump replacement. Any idea why this is happening?
Second part of question...
Am I able to leave the pool suction valve to 100% and the spa return valve to 100% and heat the spa, which then spills over to the pool? When I do this the heater seems to work fine, but am I just sucking cold water in from the pool and putting it in the spa? Or will that water in the spa eventually get up to temp (100 degrees or so) and just spill over into the pool while the spa remains at temp?
Included pics of current set up. Pool suction valve open to 100% and spa return open at 100%.
Thanks for your help.
