Hello Team GMC, I'm making progress on the interior refresh of my 1975 Royale.
The deconstruction is coming along, I have all winter but I'm in need of more direction.
I believe the fresh water tank is original to the coach, after draining the tank I noticed several items... First, during the PPI the tank was filled to identify water leaks, no real issues related to leaks although the PPI revealed the water level gauge went as high as 3/4 even when full, perhaps due to the sensors in the tank? I tried to unscrew the wires connected to the sensors but no luck so I popped them out so I could remove the tank.
Where can I purchase replacement sensors, if they exist? The ends appear quite corroded.
Is this a straight forward repair or do I need special instructions so I don't have a major leak down the raod... literally?
The main fresh water supply on my coach is at the left rear just behind the generator compartment, the water hose travels along the inside rear to the tank. I also see in the propane tank compartment (right rear) there are two additional water connections, one larger with a hose diameter approximately 1 1/2"? enters the water tank at the upper corner and the other connection (smaller diameter maybe 3/8") also enters into the coach and into the water tank at the opposite upper corner, what are these two connections for?
The inside of the water tank appears dirty, is there a cleaning solution that you recommend, say a water - vinegar mix that can be used to clean and sanitize it?
As always I look forward to your suggestions and appreciate your help.
Stay Well,
Mike

Mike,
Warning: I don't have a Royale. Someone may choose to correct this.
JimK at Applied has the level sensors. Both are better as they are magnetically coupled and have no seal to fail and leak, but both were apparently designed by Cinnabar and are terrible for accuracy. Mine sticks at full and I have to go beat on the tank for it to drop and read the level the one for the black does not even detect the bottom or top third, but it does indicate half pretty well.
The water connection at the left rear (port-aft) goes directly to the pressure potable water and does not fill the tank in most coaches. You can add a valve if it does not. The large line is in the case that you have to put water that is not supplied by pressure. This is like the open end of a hose, and it only goes to the tank.
Vinegar will not sterilize much. Unless you take the tank out or put a service port in the top, you really can't clean out the many years of sediment. Use swimming pool chlorine in a dilute solution or hot tub hydrogen peroxide (needs gloves and eye protection) and like it better because you don't have to waste a day trying to get the chlorine taste out of the potable system. We do use ours for drinking water, but then we always did on the boats too.

We travel with pets. We carry bottled water to keep their systems regular. Strange water can cause upset and the results are not pleasant.

He might have the sensors that are wires attached to the side of the tanks rather than the float ones.
By the way the magnetically coupled sensors are an 8700 series Liquid Level Rochester Gauge that have been around for many years.
I first bought them from Golby in Florida many years ago.
I don’t think they were designed by Cinnabar.
Jimmy wrote that he had a 75 Royale. Did Coachmen use the studs into the side of the tank as the level gauge rather than a float?

Mike, I put 2 boat deck inspection covers on the top of the tank for easy access.

Thank-you all for your ideas and suggestions.
I too was hoping that someone else with a Royale of the same vintage might be available to offer input. A short time ago I asked on the forum if there were any other owners for this very reason, however, nobody replied. I did receive input from a fellow Canadian who has a 77 Royale.
Adrien, thanks for the suggestion, which one's did you install, I like this idea as an option?
A. Hamilton, thanks for your suggestion regarding the sensors, this one, http://appliedgmc.viaretailparts.com/10-1170 looks closer to what I removed but not identical. I probably shouldn't be looking for identical as these items may have changed over the last 40 years.
My sensors were attached at the side of the tank, 8 in total, 2 side by each. A wire connects to a screw with what appears to be a black washer followed by 2 small nuts... if I can only figure out how to create a folder on the photo archive I could then post images which would make this process much easier.
Thanks again for the ideas, I'm still trying to figure out what the other connections are for?
Regards,
Mike

I answered that I had an Ex Royale....
My black and grey tanks are original, they still say 1976 on them
The level sensors are just rubber rivnuts, you can get them at the local Ace Hardware store.
rip the old ones out, don't bother trying to unscrew them, it won't happen.
LIke these
http://www.hansonrivet.com/rubber-nut-threaded-inserts.htm
Well Nuts : Hanson Rivet
www.hansonrivet.com
RUBBER-NUTS are a flanged rubber bushing with a brass machine nut molded into one end. When seated in the work piece, a conventional machine screw is threaded through ...
When I say rip, I mean carefully twist and work them out so you don't break the tank.
Or cut the heads off and push them inside the tank...
I think I paid extra and got stainless, hopefully the next time the mice eat the wiring I can get them loose

Would either of these work?

Mike,
The original level sensors for the potable water and black tank are no longer available. They were a POS anyway. The level sensors from Jim K are a good replacement and I have used them in our first coach and they worked well . The 75 Avion and the 78 Buskirk Stretch use capacitance level sensors that work good too.

I have this one and it work well in the stretch.
