I am not sure how to set my valves for the spillover spa.
I know the spill over raises the ph and I am wondering how would the spa water be affected if I stopped running the spillover.
Do the drains in the spa circulate the water enough to chlorinate and turn over the water?
Thanks
 
big,

Unless you have an automation system that controls your valves you are stuck running the spillover all the time.. The only other option is to go out on a daily basis and manually set the valves.. which of course is never going to happen.

The spa will turn green in few days without the spillover working..

Big,

Not sure if you're asking about which valves need to be turned or how to set "spa mode" using automation. Since you have automation I'm assuming you're asking about the latter. I run the spillover an hour or so each day to make sure it does get chlorinated. The time it can run without really depends on your chemistry and balance. I have personally validated Jim R's comment. If I don't run the spillover for a couple of days algae will form on the walls at the water surface. I'm sure it would get real bad in a hurry. You can check your pump curve to get the flow rate to determine how long it takes to get one turn. Probably 30 min would work well in my case.

If I got this wrong and you're really trying to figure out which valves to turn please send a photo of your equipment and valves. Then we'll figure out how to advise you.

I hope this helps.

big,

At first glance it does not appear that your valves are set up like the standard way a Return and Intake valves are normally set up.. :scratch:

The first thing I would try is to shut off the manual "Spa Floor Return" valve and see if that makes your spillover stop.. Just as a test.. I would not leave it that way for now, until some can determine if your other valves will make the spillover work or not..

Let us know what you find,

Jim R.
 
Thanks Jim.

I turned off the valve labeled Spa Floor Return and the spillover did stop. After that I turned the valve to the position that turns off the bubbler on the shelf and left it there so only the spillover was running.
The Omnihub can only control two actuators so I cant add additional actuators to control the other valves.
 
big,

In theory you should not have to add an additional actuator. The two valves that your system should control are the Intake valve an the Return valve.. To run the spillover function the automation just moves the Intake valve so that it is sucking from the Pool and sets the Return valve so that it sends water to the Spa..

If this were my pool, I would set up the Spillover and see how it works... Just because it is set up does not mean you have to use it if it does not do what you want...

Thanks,

Jim R.

I would keep the "Spa Floor Return" shut off and see what happens.. I would leave your other manual valves wherever they normally are.

You should not have to wait for a schedule to run it.. You should have a Spillover icon that you can just try...

You want to make sure when it goes into the spillover mode, that if something is wrong, you can be there to switch it back to the Pool mode. In theory, if you are in the pool mode and push spillover icon, one valve should turn to send water to the Spa and the other valve should not turn at all.. (Obviously, I am talking about the two automated valves.)

Perfect... :thumleft:

Now you just have to make sure the schedules are operating and then compare the FC in the pool and in the Spa every few days.. If you see the FC in your spa start dropping too much below the pool level, you will just have to increase the spillover time...

Thanks for the feedback,

Jim R.
