Lost my water supply coming into my toilet. Water worked everywhere else in my 2018 26ft RB FC. Found the water valve in the area behind the toilet switch which was accessed through a panel door in our storage cabinet.
Water valve was jammed and would not function. Even though itís kind of hard to get to, it can be easily removed by uncoupling both the water intake and output along with two spade wire attachments.
The bottom portion of the valve assembly is listed on the Dometic parts list as ďwater valve kit # 385311882Ē, but as I found out, they changed the part number recently to 88074.
If you canít get a replacement part right away, I made a manual water valve that can work temporarily.
If you need to order the valve assembly, I strongly suggest contacting Ardemco Inc in California (authorized Dometic parts supplier) at 9497227672. They had a great customer service dept and excellent service.
Hope this helps.
