what size drain hose for grey water only

[HazMatt]

Is that a kwik-konnect at the discharge end? This Android's zoomage is inadequate to the resolution.

An early lesson for my non-rural Environmental Science classmates was that one universal constant:
That being that $h!t shows a preferentially strong gravimetric tendency to trend downhill.
I don't begrudge the surplus discharge times by using a macerator & a tasked garden hose. Gotta love that the hose can afterwards be threaded together entirely water-tightly!
What else's not to love? I can pump that crap UPhill, AND have it complete the chewing of any kernals of corn I may have discharged over-toothed, and left un-masticated...

Brass 3/4" pipe to hose bib with a brass cap to assure no drips on the road.

wow... that's fancy

I just used garden hose for the drain.

We just have a tiny galley sink that I re-purposed from one of the sailboats... It has a small electric faucet, looks a lot like the old dental chair water faucet.


We only have a 13 gallon freshwater tank, and no holding tank. The sink is just for handwashing/contact lens mostly. We rarely use it and it's not any worse than just rinsing hands outside with a bottle of water.

Not marking one's presence on the byways is a REALLY good thing.

Not marking territory in camp is *even* better!
Thanx for the clarification. [emoji106]

The standard outlet for grey water is 1 1/2 inches. Our grey tank came with 1 1/2” fittings pre-installed and the Valterra waste valve we bought is made in two standard sizes - 1 1/2” for grey and 3” for black. So I would think that while 2” would be large enough, it might make finding fittings difficult or you might have to use an adapter to step down the pipe size before your waste valve.

Thanks for that. I've decided to stick with the 3" hose diameter and simply adapted the plumbing between my 2" gate valve and the outlet to that size.

I can't find 1.5" drain hose from anywhere, which is what made me decide to stick with the industry standard 3" configuration.
