Thank you to Gail Miller for the resources linked below. On p. 8-13 etc. of the owner's manual, there are some notes on winterizing, and the valve being discussed in this thread is mentioned I think, but I don't see any photos or diagrams identifying it thoroughly. [PDF p. 76/86]

FWIW

Thanks for making this drawing available to the forum. I like having detailed documents like this.

I wonder if that's a copyrighted drawing?? I added 'unlabeled valve?' to the drawing, via Photoshop.

Maybe the drawing is in the new manual or parts book you posted?

I do not see the drawing in the Owner's Manual, it is in the Parts Manual, but the valve is unlabeled.

Just took delivery of 2017 Basecamp.. appreciate all the good info on forum! We had same issue with bypass valve. Was left open so hot water would only last a few seconds then turn cold. Closed valve, but now there is no hot water pressure. We're hooked to a water supply at camp site. Any ideas?

Any hot water in sink? Just a shower problem? Do you have cold water at both locations and just no hot? Pop drain valve on hot water tank to make sure it's filling up from your water supply.

No hot water in sink or shower. Just a trickle on hot setting. Cold is working.

Have you reviewed Gail's drawing in Post #45? Apparently this plumbing schematic may be a newer version than what is in your owner's manual.

Near the label "Water Heater Connection" on the left center, there appear to be at least two valves just downstream of the heater in the red line:

1. at the top/start of the red line; and
2. a mixing valve (?) in the middle of the red vertical run (the round thing unlabeled).

I would make sure you have located each and every valve shown in the drawing. You still have a valve closed somewhere in my opinion.

Or, if that is indeed a mixing/tempering valve near the water heater -- to prevent scalding hot water from proceeding through the lines to the showers and faucets -- it may be defective. Here are the search results for "bad mixing valve" which would include other AS models and valves FYI:

https://www.google.com/search?q=bad+...=airforums.com

Good luck!

Peter

If you can find that mixing/tempering valve, I would just turn its adjusting knob back and forth a bunch of times. There may be crud in there, which manual changes will loosen. If you can hook up to city water and have the hot water running while you do this, it will help IMO. Even on just the pump you hopefully will get some action.

Good luck!

Peter

PS -- The Truma unit is both a furnace AND a water heater, isn't it? I would read their manual, and look for any additional valves etc. they talk about. Maybe there is a stuck or broken check valve inside the Truma unit? As you have probably seen, the earlier posts on this thread also talk about the Truma control panel and how to adjust for hot water. Probably not related to your current problem, but worth a check IMO.

Hot water working!

Yes, you were right, there was another valve in play. Patrick at Colonial Airstream helped us out.

The by pass valve (number 7 in the picture) was open when we picked up the B.C. We closed it after reading the thread. This does appear to be a valve that should be open during winterizing, but closed during normal use, or only cold water flows. We closed it, but then there was no water from hot faucet.

We then opened the valve labeled 8 in the attached picture. And hot water flowed like a dream! This valve is near the back under the triangle shaped cover in the seat next to the furnance.

Thanks everyone. I hope this helps.

Also, we only had the BC for one night..

As I was saying, we only stayed one night in the BC and then we drove it from NJ to NH behind our Highlander. We love it. We did not encounter the problems noted in the threads, so maybe they have been addressed with the new shipments. Terry and Chuck
