How Do I Stop The City Water From Filling The Fresh Water Tank On My 5th Wheel Trailer?
by Lynette Brennan
(Oregon City, OR, USA)
When I hook up to city water in my 1993 Nomad Fifth Wheel it eventually fills my fresh water holding tank. I thought that the two were separate.
I leave the city water on till I know it has enough water to use pump and then turn the city water off. I looked for some kind of valve I could switch but didn't see one.
I would appreciate any info you can give me. There are separate compartments for the city water and the water tank fill. The rig is new to us and I noticed the problem when we went camping for a week and there was water running out the fill compartment. We have never filled the water tank. I even drained the fresh water tank to see if it would fill again and it did.
Thanks for any help.
ANSWER: Greetings Lynette thanks for submitting your question on our Ask An RV Question Page.
I am a bit confused on what is going on with your 5th wheel Trailer. The fresh water system on your 5th Wheel RV should fit in one of the two categories below.
1. You only have one fresh water connection. In the compartment where you connect the Fresh Water Hose is a valve or lever which is marked with 2 positions. The Valve or lever has a tank fill position and a city water position. When the valve is set to city water position no water should be entering your fresh water holding tank.
2. Your 5th Wheel could have two separate Fresh Water Hose connections; one should be marked as "Tank Fill" and the other one should be marked as "City Water". When you are hooked up to the City Water connection no water should be going to the fresh water holding tank. In some cases these connections could be in separate compartments.
Hopefully this information has been helpful to you.
