Standpipe question

[chansen]

Need some advice on dual corner overflows. I have the same as shown in each corner and have been looking at other designs and most I have seen have some type of emergency drain. I have two 1” overflows and two 3/4” returns. What would be the most reliable in the event one of them gets plugged.

Your overflows appear to be set up for durso standpipes.

You can convert this to a dual Herbie drain tank if you’re willing to run return plumbing up the exterior (probably rear) of the tank?

Thanks for the input, much appreciated

With dual drains I would simply ensure your returns can drain through a single by simulating a one pipe clog and calling it a day. You have redundancy already with dual drains, you could run one drain slightly higher than the other and make it a straight pipe so if it’s in use it’s loud and splashes the water as it entered the sump to tell you something is wrong.
