Ben's DIY Graywater System

I have the system working.

Right now, the PEX runs across the hallway, from the utility room, down the hall, straight to the toilet.

It's just set up like this to test out first. I don't have a drill bit that will go through tile, so I will do that when I get the tile bit and a little more time.

Overall, it seems to work pretty well. I think my pressure tank is a little undersized. That's only 2 gallons, and I think my toilet tank is more than that. Perhaps I can store more pressure with a length of 4" PVC pipe with end caps on it.

The pump runs for about 25 seconds when I do a full flush of the toilet tank. The pump internally has a pressure switch which kicks on at 30 psi and off at 50 psi.

For some reason, I have a leak between the 3/4" to 1&1/4" adapter, and the 1&1/4" pipe going into the pump. It looks like they are straight on to each other, so I don't think they are cross threaded. I used teflon tape (wrapped the right direction!)

Not sure why it's leaking. Maybe I just need to buy a new set of adapters and start over!?
