I have resolved myself to only 2 possibilities after looking at the actual plumbing: 1. Someone turned on the pump; there was no water in the tank and the incoming water pressure exceeded the backflow valve and/or pump's ability and backfilled the tank 2. The backflow valve has failed I cannot...

Our daughter is living full-time in a 2011 BigHorn 3670L. She has been for about 18 months. I was checking the cargo area, and I have found water leaking from what I understand is the Gravity Fill hose. The camper is fully plumbed to an incoming water line. i.e. we have not ever used the...

Hello, We have a 2011 Bighorn 3670RL. We need to replace the main AC unit. We've been reading and researching, but still have questions. It appears that the original unit was 15K BTU's (no heating capability). I am unsure on the brand, but the wall thermostat is Dometic. Do we need to worry...

Thanks for all the information. The 'pop' was the cable on the backside of the panel where the handle is. I did not take a pic, but the outer shell disconnected (tore?) from the threaded part that goes through the wall. Thus, there was no tension when pushing the valve to close. The whole cable...

I saw these in some of the videos I watched. I agree that I could install it at the exit point, but wouldn't that mean that 'black water' would be filling the pipe all the way up to the point of this new exit valve? i.e. What would I do with my current black tank valve?

Removed access panel for a look. This is what I see: The underlayment was put on after before the plumping was connected. Thus, even if I remove all screws, I will still have to cut it somewhere to get around the pipe that goes down to exit the trailer. I don't want to cut it, but that...

Hello, relatively new still to our trailer. Bighorn 3670RL (2012). The trailer is permanently hooked up to a dump station. We leave the gray tanks open and regularly dump the black tank with a good flush. Today, the black tank valve didn't seem to want to close. Eventually you could hear a...

Hello, We have a 2011 Bighorn. On the bedroom slide, the wiper seals are 'different' than all the other slides. The other slides have the wiper seal connected to the 'track' that holds the D seal. I assuming I can just remove the screws and replace the track/wiper seal on all these slides. The...

Hello, new Bighorn owner (2011 3670RL) here trying to learn about our trailer. I need to replace the intake valve in the toilet. We have the trailer hooked up to "city water". In a house, I would have a valve at or near the toilet to turn off the water. I see no shutoff valve like that in any...
