Automatic Water Changes with Apex using PMUPs

How are you stopping the pump from siphoning all the water out of the sump when it shuts off?

I don't use a neptune pump, but same difference- you can put a tee at the highest location- preferably still above the sump. Then put a valve on the line to restrict the line-- it will lose little if any water, but be able to suck plenty of air. Or you can use a bit of tube and tie it in a knot to restrict it- I've been running mine that way for years with no problems

Put a valve on the tee on the air side? Can you share a pic? I guess just introducing air into the line will break the siphon

Again, a double post....

sure- excuse the mess- it's a basement sump so looks don't really go for much

That's great, thanks! I will try this. i assume you aren't getting any water out of this due to the path of least resistance being the outlet of the Tee?

Yes, I don’t get any water out- I think there is actually a slight venturi effect

The manifold of shut-off valves for the lines out to my garage. These lines run about 40 feet up through the attic and then down the wall to a cabinet in the garage, where there is another set of 6 manifolds on that end:

Where might one find a manifold?
