Hey all - Happy 4th!!
I have an interesting question I hope some of you can help with. I dont know why it took me 4 years with a spa attached to a pool to think of it
I understand how the flow of water works pretty well.
Normally when I have a party, I like to leave the spa on. The problem is, when I do this there is no pool filtration going on. After a few hours of dozens of kids jumping around, the water can get cloudy...
So my normal idea would be to return most water to the pool, and just a bit to the spa. So the pool returns are on, and water is being pulled from the pool. This solves all return water issues. It just weakens the spa jets which isnt really a big deal to me.
But this causes a problem heating the spa or keeping it at a desired temp. Because the heater thermostat uses water from the suction side. So therm will see water at 85 or whatever instead of 100. And the heater will remain on. Now because im constantly getting some pool water into the spa, I dont think anyone would boil like a lobster . But it does make it impossible to control properly like when Im in full spa mode.
Sorry for that long winded rant... My question is, how do you keep some filtration in the pool and spa and still control the spa temp if the heater therm works off the suction side water?
Thanks a million for any help or ideas and have a great holiday!
