My objective here is fun.

After 20+ years…and quite a few miles we are in a water and electric site for a few days…gurgling sounds…water in the shower…I run to the sewer tub, grab my never-used, twist-on gate valve, start pushing and pulling gates and minutes later, the gray tank indicates 1/3…

Problems solved…

The best part: 12 hours later, the camper still hasn’t exploded. [emoticon]

Mild seriousness: glad I bought the thing 20 years ago.

Yup, I've carried one for years, in case of emergency. Still unused, but ready when needed.

I leave mine on all the time. Prevents surprises from the other two valves if they were to leak.

Exactly the twist on valves work better than a sewer end cap

Two of the mods Dad and I did to his 5th wheel when he started full timing. Install a third valve near stinky slinky hookup so at least 2 valves had to be open for anything comes out.
The 2nd was a second drain, with 2 valves, about 3/4 up on grey tank. With both open, grey water would bypass the main valve, and if the added valve was open, thru stinky. Close the lower, the water exits thru hose bib. Close top valve, and could back into shower.
On FHU site, he would run small hose from hose bib to sewer, or where allowed, into bushes. Live as normal, (normal, for him, was dump dish pan down toilet. Food bits and soapy water help move the cornbacked rattlers) until black full. Hook up slinky, drain black, have plenty of grey to flush, stow slinky.
If he had guests on a E/W site, shower fill tank, he would drain a few buckets dump into black tank.

No concern about possible black water mixed into the gray tank/lines?

It’s now been 24 hours. The camper still hasn’t initiated a runaway nuclear reaction. Should I be concerned?

Four serious comments:

1. Gray water flows into black, not the opposite.

2. These things mix daily in regular houses.

3. Food waste + water + soap + anaerobic bacteria = plenty of nastiness in gray water tanks.

4. It’s preferable to gray water coming up in the tub.

Does it matter? It's all waste water. THe grey and black mixes in you stand brix house!
A good trick to use when you need additional tank capacity is to
close twist valve. Open Full grey tank and then open black tank.
Excess grey water will back fill into black tank. Creating additional space in grey tank. You can gain 5,10,20 gallons of additional grey tank capacity that way depending on the size of your tanks.

In Fleetwood's infinite wisdom, my Bounder came with 2 50 gallon waste tanks. DUH! I add a gray water transfer pump to balance the waste water storage.

If both tanks use the same drain. Put a twist on valve on the outlet and close it.
Open both tanks and they will equalize themselves.
