Anyone using a watersaver and if so, how did
you plumb it?

The old Revcon MH had an adjustable 12v DC
timer in the hot water line to the shower.
It timed on a 12v solenoid valve that pumped
the cool/cold water in the hot water lines
back to the freshwater holding tank, so you
didn't waste the water down the sink drain, waiting for hot water. You poked a button, the water
pump ran and timed out, and when you turned on the hotwater it was hot....it served two purposes: it saved water and did not fill up the gray water tank as quickly.

Eddie,

I have not been able to find a site that has a commercially available water saver like you described. However, I did find one that has a home brewed water saver circuit. It is designed for a marine application but should work just fine in an RV. Do you know if there is one that's commercially available?

Here's the site

Paul---
I'm glad you found that website and article.
Good job....
The Revcon set-up used a timer and it must have
been a trial-and-error deal to figure out how
long to run the pump for hot water at the tap.
I figure the timer had a set point on run time
and you just fooled with it until you got it right.
The 12-v solenoid was located in the
plumbing run as far away from the water heater
as was possible so it charged all the hot water
taps (faucets) in the run. Do not know if there
were push buttons at each hot water faucet in
the Coach, but it makes sense.

Glad that that you could see the benefit of this...
in so far as I know, there are no
units like it for sale in the market...
