Stumped! Fresh Water Problem
Have a 2016 Greyhawk 31Fs. Been out a couple times this year, and many last year and have used tank/pump as well as city water and had no issues. Last week, we went out, hooked up at campsite and NOTHING, no water. I cant get system to take water or fill tank. I was able to fill tank by crawling under and connecting line straight to tank. Got us by and used full system with tank and pump.
Worked on it yesterday, thinking it was either water inlet check valve or check valve in water pump. Replaced inlet and pump and still cant get any water from city water connection, either to tank or to fixtures. The control panel seems to be working fine and have checked all valve settings and found no issues. Seems that something is blocking/stopping after inlet.
The inlet line runs behind bathroom but not sure where it runs to directly. No access to most of the line.
Anyone have a schematic for the 31FS? Are there other valves in the system that could be the problem?
Getting water into tank by hooking directly, all fixtures work and system pressurizes and no problems.
I am stumped and any advice or suggestions are welcome!
Thanks in advance.
