Unable to find a water tank filler inlet on the 88 Regal, 25 footer. Tank is in the back centered half under the bed half under the shower. Only seems to have a campground, city water inlet on the drivers side about center coach. Have opened every access door on the coach looking for a for a fill access to the tank.

You just hook up city water to coach turn fill switch
on control panel to turn solenoid on and tank should fill. When it is full solenoid turns off.

Found a hand valve under the bed, opened it and Boom, city water into the tank!

Craig, will check for that auto fill, however next to the hand valve was a loose hot wire that I taped off, wonder if the auto fill has been removed.

Duane, If you have a solenoid valve it may look like the one in this picture although the solenoid wiring is removed, since the picture is the fresh water tanks out of the Barth.

Some PO removed the electric valve and replaced it with a hand valve, its ok just have to remove a drawer to get at the valve to fill the tank.

To drain the tank, have to open the hatch access, remove the mattress, real pain!

My manual fill valve is slightly lower right of the solenoid valve. The manual fill or the solenoid fill valve will fill both tanks, because I installed the 1 1/2 inch equalizer piping between the tanks. It equalizes only when the blue valve handle is open. I can also fill tanks from driver or passenger side of the Barth.

When sterilizing me system, I dump a quart of bleach in the garden hose than hook the hose up to home water. I leave the tanks for a day. Then I drain and refill with fresh water. This little trick was included with my previous owners Barth file box. It was an old magazine article, I am sure Bud used when he traveled to Florida for the winter. Do not over bleach because bleach will harden polybutylene plumbing.
