Siphon break on my retun lines

[Kevin McG]

Got the tank full of water today and tested out the plumbing. Killed the power to the return pump and tested the max sump level and I noticed the sump just kept filling. I didn't realize the temporary return lines I am using were still submerged and when I pulled them everything stopped draining and no flood by the way


Ok the question, where is the best place to put a siphon break on the retun line?



Other than that everything went great no leaks, no floods and quiet operation

I put mine about 1/4 inch below the water surface. Cool thing about it was it actually acted like a little powerhead on the surface.

Drill a few right at the surface when the return pump is off. When the pump is running they'll be 1/4" below the surface. Make sure you drill a few and keep them cleaned out, because they are sure to get clogged.
