I own a 2015 Ace 29.2. After locating the low water drain point and draining all the water, I closed what I thought was the hot water bypass valve and also drained the water heater. Closed everything up, leaving what I thought was the hot water bypass valve closed, and began to fill the system with antifreeze. After quickly draining my only two gallons of antifreeze with nothing yet at the taps, I stopped. I checked the hot water tank, and it was full of antifreeze!!

Can someone confirm the location of the hot water bypass valve on my 29.2, or tell me what the hell I did wrong???

DAMNIT...lol

So, did you get 6 more gallons and just fill it up along with one in the pipes or did you drain the 2 gallons and start over?

I have to pick up some more antifreeze so I can do it right, but don't want to have to fill the whole hot water tank each time. I need to figure out this valve issue.

I don't have your model, but helped neighbor last year with his 2014. Do you have three valves under the bed (or next to water heater)? If so, you have a cold water supply line going into tank-it should be closed (perpendicular to line); you have a hot water line out of the tank-should also be closed. You have a cold water bypass-should be open (parallel to line). The bypass allows water to go to the hot water taps so you can get antifreeze to them. Reverse the three valves after you flush the antifreeze when you de-winterize.

If it were me, I'd drain the antifreeze from the tank and flush well and drain instead of letting it sit all winter.

I did not find any valves at the water heater. I found one near the water pump that looks like it runs towards the water heater?

Pictures of different by-pass setups here.

I doubt the one valve at the pump is the right one. 007's post should help you identify the configuration. My buddy's valves were under the bed. You -could- have a one valve system, but that valve would be clearly marked with a plastic sign that indicates "normal" and "bypass". Looks like this:

How hard would it be for THOR to actually include a effing manual!??!?! DAMNIT.

I would be ecstatic if someone that had my model could post some pics!

The 29.2 water heater bypass valves are under the bed. Turn all 3 valves

Hey thanks! You have any idea what the valve is by the low point water drains and pump???

Not sure without going out to look but I do know the valve just above the pump is the shutoff from the fresh water tank. And I believe there are 2 low point drain valves, one on each side of the pump. The one on the left will drain the lines going to the faucets, the one on the right will drain the fresh water tank.

Yeah...you're welcome.

That valve closes off the water tank to the pump line. If you leave it open and blow out your lines you will have air coming out the breather in the watertank on the side. If you close that valve then it only blows out the other way(to faucets etc.)

Thanks Harlee, now all my questions are answered!
