Nevin's 14G + 5.5G sump

[Nevin]

First leak test tonight. The return plumbing is pretty leaky--I used a few pieces of plumbing intended for sprinklers that seem not to be a perfect fit with the rest of the 3/4" PVC. It's glued well enough that I can't pull it apart, but not well enough to hold water... I have most of the parts I need to redo it, but I'll have to try to drill out a part that's glued into the check valve tailpiece. Though the check valve is a true union type that comes apart, I don't think I can buy just a replacement tailpiece.

The tank picture follows, finally with some water. I'll probably try to bring the sump water level down a bit. As it is, a pump and check valve failure would likely cause an overflow into the stand (which is sealed with silicone), but not onto the floor (which would be a disaster).
