It drains below the water level.

There is a small hole on the drain pipe in the sump, above the water level (at the exact same height as the first baffle), draining water into the sump, making a loud trickling noise (or peeing sound, as my husband says!). It's really peeing out water. When we hold our finger over this hole, a lot of the noise is gone. Can we permanently block this hole? The sound gets a lot better when we restrict the flow from the pump. When the flow from the pump is cut back by about 1/3, and we block that little hole, then the sound is OK. Is it OK to restrict the flow that much?

Another thing... when we cut the power to the pump, the overflow drains into the sump. The standpipe?.. the pipe in the overflow? fits into a larger pipe (creating a gap at the connection) about 3-4 inches above the bottom... and water seems to drain into this gap. So the overflow box becomes empty except for the bottom 3-4 inches, when the power is out. Shouldn't it stay full in case of a power failure? I've heard of people having stuff growing in there.. you wouldn't want it to drain! Can we glue/seal those pipes together so it won't drain? Is there a reason we should not do that? It could have been glued together, but it wasn't.
(I've forwared this message to Mike at HR, who responded super quickly to my post! much appreciated Mike!) I'll see what he says...

Another question! I've read that some people suggest widening the little hole (what's it called again?) right on top of the standpipe (Dur... something or other?) in the overflow box? Is that something we should try?
Thanks!
