Basic Sump/plumbing question

[aiber]

When plumbing the sump, is the end of the drain pipe going into the sump suppose to be submerged underneath the typical waterline of the sump?

You mean from the overflow? Is there only one pipe? If the pipe from the main drain is not under water then it will make noise. The emergency on the other you want to make noise so you know there is a problem. I think about 1" below the water line is good for a main drain pipe.

Generally speaking, yes. But how you do it will depend on the type of drain you have. If it is a full siphon, then yes, an inch or two below the surface will be great. If it is a Durso style, then I would suggest that you add a "T" to the drain so that the "leg" of the T is just above the waterline. This will allow the air in the line to escape decreasing the noise and salt spray.

Thank you but I don't think I am explaining well enough. I am using the herbie method. I am referring to the pipe that goes down into the sump. I think you are talking about the plumbing in the overflow. For example, where people put the filter sock.

Yes, the drain needs to be submerged. But not too far submerged, or else bubbles won't purge during startup. 1" below is a good place to shoot for.

Typically you want the water level in the drain area of the sump to remain constant whether the pump is running or not. Then make sure the main drain is about 1" below the water level. This way the siphon is never broken and makes for a smoother startup if your return pump has been off. Also has the added benefit of no splashing noise.
