First DIY sump build. No drill overflow part 2

Getting a few kinks worked out. still have a long way to go before I leave it run when I'm gone.
What would you do different?

I ran one of those for a year+ non-stop before I moved and it worked perfectly. Even through power failures.

To make mine more quiet, I grabbed a spare bulkhead I had kicking around (the kind with the threads, but a rubber one should work) and a 2 inch length of vinyl hose still attached to it. Dropped it in the top of the vent pipe and cut out 80% or more of the noise. The vinyl/rubber seems to deaden the gurgles and the bulkhead piece just keeps it from falling down the pipe.

Drill a small hole in the cap to prevent full siphon. The air tube is not necessary in this design.

If they aren't glued they are sucking air. Need to glue and put the check valve on your cap

[@CourtnRob]

Yeah, I thought it could be a problem. Leave the check valve that I have (just glue it)? Install another one on the cap?

[@ReelHardFishing]

@@CourtnRob you can leave the one you have and just glue it, add another to the cap. If you can still prime the overflow from the chef valve you just added on the cap, eliminate the one on the overflow itself.

For quiet operation, adjust the ball valve so that the 2" weir has more water in it. You only want about 1" of drop into the weir.
