I equalize the tanks a lot. I have a clear section and a cap with the garden hose connection. I open the grey then the black. When the swirling stops I close the black then the grey valves.Removing the hose cap allows me to drain the remaining water into a cutoff milk jug.I have used a twist shutoff in place of the hose cap but it drains much slower .Haven't had a bath yet.Notice YET.

That is a valid point but you would only get gray water out when you remove the cap. The gray water goes to the black tank and no black water passes the cap. Gray water is bad enough but a quick rinse will take care of it.

i have the valtera twist on valve that skigramp mentioned and posted a link to.

i have used it to ''equalize'', add gray water to the black tank. it works ok.

i carry the twist on always in case of a drain valve malfunction.

I always start my gray tank dump first then switch to black then back to gray when the black tank empties and let the gray empty. This way if you do like I have done and had a leak it will be gray and not black water. Also washes your hose. But I'm sure all you oldtimers knew this. More work but can save a mess if your'e in a hurry like me with DW and kids waiting to go to beach.

i likewise dump some gray first to check the integrity of my stinky slinky and fittings.

then i dump the black tank and flush it 3 or 4 times.
then i add 2 cups of bleach to the gray tank, let it sit for about 5 minutes and dump the rest of the gray tank. the bleach sanitizes the stinky slinky and fittings and deodorizes as well.

We have the three tank arrangement -- black tank (51 gal) for toilet and bathroom sink; gray tank for shower/washer; and, gray tank for galley/dishwasher (two gray tanks total 117 gal). Freshwater 103 gal. We've not had a problem going for a week before we dump if we use the park restroom facilities once in awhile.

Hey Dan and others,

Thanks for the idea about the bleach in the tank. I use tablets in my black tank but have yet to install the tank wash spray head in my black tank. There is a great RV supply place 8 minutes from my house in San Antonio, their catalog is about 2 inches thick. What they dont have they can get, cheap too. They have lots of stuff for the sewage dept of RVing and the tank wash head is on my want list.
Good idea, Thanks again. By the way I'm kinda an old timer myself refering to my earlier post, sounded kinda smarty pants like.

When boon docking the gray fills up much sooner than the black, I installed another pump so I can pump the gray into the black tank using an end cap with a hose connection. I inserted a pvc hose connection w/turn off valve at the top of the black tank. Works great and extends our stay several days. To see pictures go to Photos and click on Members Galleries then search Bruce H and click on picture.

A slightly better suggestion is provided by one of the sewer adapter companies.. I think Valterra but it may be Camco (or both)

I believe in the Valterra line it is model T-58, A "Twist ON" waste valve

One document you may wish to have on your hard drive is this one:
Valterra RV catalog.PDF

The valve is on page six
