Drain bulkhead in sump

[Kdocimo90]

Is it ok for a drain bulkhead in a sump to be below the water level (ie draining water underneath water)

What are you draining the sump into? If you are asking will it work, as in, not leak. The answer is sure. If you are asking is it a good idea, then we need to know what you are trying to do. Sumps commonly get a layer of silt, sediment, detritus on the bottom and drawing water off the bottom might not be a good idea depending on your application. You could also set up a short pipe inside the sump so you aren't taking water off the very bottom.

I think you are referring to the drain from the DT to the sump. I prefer to have it just above the surface in the sump to help prevent back pressure and excessive noise from the sump area. If you have it below the surface, you might want to add a pvc "T" fitting sitting so that the T is just above the surface - this will allow any air to escape from the drain line, minimizing bubbles.

Never tried this as I plan from moving away from my filter sock in the near future. When I don't have the filter sock in there I get tons of bubbles.

Def. give this a try thanks!

Billdog is correct. The only reason why I plan on doing so is because my frag tank is beside my sump. So the only way to get the drain lower in the sump (in comparison to the frag tank is to have there be a low bulkhead in the sump.
