Any other harm other than slight water loss from spa dropping level if I converted a Jandy check valve to a two way valve? And can I even do that conversation by pulling flapper on check and buying the Jandy insert kit with handle?
Many thanks for this forum so much info and fun to participate!Longer story and a thread started by me on the yo-yo of Muratic acid and TA for my 43k gallon pool. My pool has a spa and circulates water into spa continually along with the side jets with an actuated valve that’s 1/4 open or closed isolating spa for spa mode. The waterfall spillover aeration causing ph to rise and the quantity of acid added drops TA. So I want to shut off the spa circ for most of the day eliminating the aeration. But on occasion I want the 1/4 open for waterfall effect. So with only two settings on the actuator valve I don’t have a third option therefore requiring another valve control. What’s the harm to a system not having the check?
I do have a drain suction line for the spa that isolates the spa during spa mode but is shut during pool modeI am in a similar predicament. I tried to balance my spa suction/supply just to the point where it wont spillover the waterfall when it is running normally, filtering each day. I agree automating this process would be sweet, as I still want to filter out the spa portion but not always aerate with the waterfall.
Do you a suction/drain return from the spa back to the pump?
What would be the plan for that line I would assume it should stay for pool mode and is automated maybe u r thinking I could automate so no waterfall which I could but I want three options Spa Waterfall and no waterfallI do have a drain suction line for the spa that isolates the spa during spa mode but is shut during pool mode
I was thinking, you could balance your spa return to match your spa suction so that you are not allowing (excess water) overflow to the waterfall. That is my hope on my end, to be able to dial it in with the 3-way valve (balance flow). Of course I am not in any automation, just manually adjusting valves.What would be the plan for that line I would assume it should stay for pool mode and is automated maybe u r thinking I could automate so no waterfall which I could but I want three options Spa Waterfall and no waterfall

Good Point. ehhh, starting to see why pool/spa combos can be kind of a mess, especially when you are aerating the water.As your filter loads up with dirt, flow will decrease and you will lose that balance. You will need to continuously monitor the balance and adjust the valve or backwash your DE filter often.
