Shower water. Where does it go?? [message #305666] Sat, 20 August 2016 16:33 Go to next message

On a 78 Royale center kitchen center bath, with 2 waste water tanks. The dry shower appears to drain into the black water tank with the toilet and maybe bathroom sink (the waste water tank on the drivers side). The only reason I think this is that I don't see any pvc running to the gray water tank (on the pax side) from the shower while inspecting from the ground.
I thought the shower water was considered gray water? Yes? No?
Does only the kitchen sink water run to the gray water tank?
Thanks, Scott.

On a 1976 Royal (1 tank) drivers side kitchen and shower, the toilet is direct to tank and the kitchen sink and drivers side shower drain into the black/gray water tank.

On the late Royale coaches with galley, and shower on the same side
(drivers) with 2 tanks, Usually, the galley sink is the only thing plumbed
into the Grey water tank. The toilet, shower, and lavatory sink drain into
the black tank. I said USUALLY. They are 40 years old, been through several
owners, and STUFF HAPPENS.

Thanks Jim,
That's gotta be it, Makes sense. That's probably why the black water tank is so much bigger..

What we do is ration the use of the lavatory sink and do military type
showers. The kitchen sink gets used pretty much like one would do at home.
That works well for Judy and I. If you have teen aged girls in the coach,
all bets are off. ( grin)

Scott,
You're correct. On our coach, same as yours, only the kitchen sink goes into the grey water tank. All on the drivers side goes into the black tank.

Scott. You need to have alittle extra water in the Black tank to help have a good flow at the dump station. In the Royale I'm building. I ran the bathroom sink into the black tank. As that's my smaller new tank. I installed a new larger gray tank that takes the kitchen sink, and larger drive in shower. Basically I switched the two sinks around from original. As in this way I was able to position the water inlet for a better tank dumps. In the black tank. I installed a horizontal fan spray nozzle so I can rinse the solids from that tank more completely. I installed my tank drain valves so I can drain any one tank as desired. At the GMCMI Rally. I won in the drawing for a macerator that Jim at Applied GMC donated to GMCMI.. I'm working that out now so that I can dump the normal way. Or the macerator.

Now I don't feel so under-tanked. I would have guessed at least both
sinks would drain to the gray tank on those Royales.

One of the few things my POs did right-ish on my coach was install a
gray tank of sorts. Under the bed there was almost 20 gallons of 4" PVC
tubing that captured both sinks. Considering my black tank is only 20
gallons I figured that was a bit much and cut it down to 9 gallons by
excising many feet of tubing. There is a valve that allows me to flush
the black tank with the gray water.

Yup. I'm pretty thrilled that my little 230 has better plumbing than
those fancy Coachman-built rigs! :^)
