    Default Hot Water in Shower?

    There is plenty of hot water, yet in the shower the tempature must be turned to the extreme and the flow turned to max to get hot water. This started two days ago. Any suggestions?

    Since around 1990, Newell has installed thermostatically controlled shower valves in new coaches. These valves maintain the set temperature even with variations in water pressure that occur with RV water pumps. Over time, the "thermoelement cartridge" that controls the temperature can fail and require replacement. When your coach was delivered new, the manual for the shower valve was included in a large loose leaf notebook of various component literature. If you can locate this manual, identify the specific cartridge with its part number in the illustrated parts breakdown. Our parts department can order the required cartridge with this information. If you cannot locate the manual, we may be able to order the correct part if you advise us of the brand of the shower valve. It will be either a Arwa Luwa or a Grohe. If you cannot identify the brand of the shower valve, another option is to have our service techs try to identify the brand of the valve from visual inspection when the coach is here.

    What year Newell?

    In My 82 Newell I could only get hot water. I checked the shower valve and it was OK. Taking off the valve cover in the closet, I found on each side of the shower valve there was a spring loaded (check?) valve. I cleaned the valves and now all works great. I guess one could remove the spring and plunger and get the same results.

    Hey Matt:

    Michael sent to me a complete manual a couple of years ago on the Grohe shower. If I could find it I'd send it along, but maybe Michael can shoot to you an email on it.

    Matt,
    We came down 80 from Reno on our way home from Creede this summer. With the Construction on 80 they have the K Rails set at 10'!!! We had a few hours of excitement with only 1' on each side of the Coach and those @!%&* K Rails and I know that some were closer.
    Just a heads up because your Coach is Wider and you will have less than 9" of clearance on each side!! Now with the Rocks that you are carrying around this could prove challenging.

    I will look for the file when I get home tonight and will post it or send it to you Matt. The thermocartridge is likely bad and will have to be replaced. They are pricey. I will look up the company I ordered them from also.
