Having the SCWD in the system doesnt change anything in that respect. Its just an easy way to have water be divereted automaticly between to outlets.

You still need syphon breaks on the return lines and you still need to run your sump low enough that it can hold any backflow when a pump is powered down.

Ok, I got it. You can drill a hole in both the PVC returns just above the water level right?

Yes.

Now just to make sure everyone is following along. You are not going to drill a hole in the SCWD! You would drill small holes just above/below the water line on the acutal PVC returns that are inside the tank that is attached to the SCWD. In my photos for example I have small 1/8" holes drilled in the short 3/4" stright section of PVC that is connected to the final 90* elbow that acutal outputs the water.

A little off topic, but how far under the main water level do you guys have your return water coming in?

That is really cool. I'm very glad I asked what that was. I could use this. My only problem is using flex tubing connections makes for a lot of silly plumbing work as I'll have to modify my 1/2" PVC return.

I've never seen them for sale. Who is supplying these?

Just about any online retiler will have them. I would of course suggest checking our sponsors first.

It wont be hard modifying the 1/2" return. Just get a 1/2 - 3/4" pvc adaptor and then a 3/4" pvc - barbed hose connector. Then slip on your tubing and into the scwd. Use some nice hose clams to secure the tubing. Then do the reverse for the two returns. I would use 3/4" though for the returns vs sizing back to 1/2".

I'll consider changing to 3/4"

Does the SQWD have to be mounted vertically, like your photo?...or will it work if mounted horizontally?
