I have to replace the gray water tank in a 76 Royale and this seems like a good time to install a macerator. There are articles and pictures on the internet but it seems like connecting the two tanks to a single macerator complicates installation. Has anyone installed 2 macerators, one for each tank? Thank you.

Jerry,
I originally had a single macerator on my X-Birchaven. Because of the
necessary geometry of the plumbing, it was difficult to fully empty the gray
water tank; lowering the rear of the coach was always necessary because the
1-1/2" gray water pipe had to rise to the rear-mounted macerator.
I finally installed separate macerators, simplifying the plumbing and
improving the dumping. Each macerator is switched independently and their
outlet hoses are joined by a tee to a single drain hose; no check valves are
needed.
I DID put a shutoff valve between each tank and its associated macerator,
and each tank has an independent gravity dump port. That for the gray tank
is only 3/4" to a male hose bib. Black water dump is 3", of course.

Do not forget to keep an alternate method of dumping the tank, if the macerator fails. Thankfully, the P.O. did install a 3" dump valve on mine. My macerator failed (impeller lost it's shape), and digging it out was not real fun.

My recently acquired '73 has only a single waste tank. I miss having two tanks 'cause emptying the gray tank after the black allowed me to flush both the Black tank and hose with gray.
But this is not a big deal.
I am planning to add a 3" valve on the very end of my waste line and then mounting a macerator directly to the valve. That way the macerator can be easily removed for service if need be.
I'd like to add motors or other linkages to my waste valves so I needn't crawl around to open them - this old frame doesn't bend well any more. Any ideas?

Dave,
Drain Master makes an electric valve. Valterra has cable operated models.
Several ways to add a wash-up-out system to your holding tank to "rinse after use".
Here is the wash system I am using..

Gene,
-- seemed like having a wash system would be good since our coach wil only be used infrequently
-- there was a hole in the tank (from a previous system) that needed to be filled...

really not necessary to wash-out the black tank.
leaving about 3 gal in the tank gives the chemicals (you add back) a reason
o grow and clean the remaining solids in the tank.
Also leaving 3 gal, in there, will allow it to slosh around and clean the
ank while you are driving.

So, on my Royale, I hooked the two tanks together with 3" pipe and use a single macerator to dump both at the same time. Works for me. See these pics:

Since the install, I did change a couple of things. I moved the storage for the hose back outside of the frame, hanging from the left side frame rail, and am putting in a solid rod from the gate valve to rear of coach. The cable thing just is not stiff enough to handle the force needed to open/close the valve.
It's just what I did!!

what size is the rear tank? mine is not original and is small; too small.
is your a rear or side bath?

Geese...I don't know how big the rear tank is, I got it 7 yrs ago from Duane Simmons. My Royale is a side bath model.

Larry - why did you move the storage tube from inside the frame to the outside?

Good idea Larry. I never thought about running it outside. My inside frame is alwo kinda congested. Think I will follow your lead on this and move it, one of these days.
I had planned to add the second D. Simmons tank. Then we got rear mounted muffler. I had Duane look and he said nope. So, I came up with alternatives.
We have a clean out like Dennis has. It is good when coach is sitting for periods of time. I use it in Arizona. Here at home, I take the rear cap off, after its dumped, and use a garden hose. Shove it straight into the tank and run it around. Could do similar by sticking one down the toilet but I don't like a "live" hose inside. I tend to make a mess. After this I put about half tank of water in the thing and close the elec. gate. ready for next use. Never had a dirty tank with this method.
