Spa standpipe loose. What happens if I try to drain the spa?

[davidwat]

What will happen if I turn off the pool equipment and throw a submersible pump into my spa to empty into my contiguous pool? Will pool water drain back into the spa on its own? I need to repair the standpipe. Thanks. David - Dallas

Please post a pic of your equipment including any valves you have for better guidance.

Thanks for your reply. Here is a picture of the system. The stand pipe threads are stripped I think, and I'll have to repair the connection somehow.

What are you calling the “standpipe “?

Looks like your Aqualink was in SPA mode when you took the picture. Show us your valves in POOL mode.

Here is pool mode. The stand pipe is broken and in bottom of spa.

If your spa spillover is not running in POOL mode then your spa should stay drained.

The spillover DOES run into pool in POOL mode.

Turn this valve handle down so the handle is aligned with the pipe and the OFF label is on the SPA pipe. That should shutoff your spillover in SPA mode.

Read Jandy Aqualink RS - Further Reading for how to enable SPILLOVER mode in your Aqualink to not run your spillover all the time and cause your pH to rise more then necessary.

Thanks for your help. I was concerned there would be a siphon effect pulling water back into the spa. It looks like water can then be sucked up by the spa drains and then be diverted away from the spillover pipe to the pool itself?

There should not be with your suction valve closed and your two return valves closed.
