I (John) noticed a puddle of water on the floor of the basement, so we took everything out and I noticed that it looked like it was coming from behind the large panel, so I removed it. I saw that it was coming from the connection to the Hot Water Bypass Valve. When I move the hose connecting to the center connection, the water sprayed out. It seemed that the black "L" connector had a crack in it. We are not near a dealer and don't have a way to move our Bighorn 3385 RL, so I decided to take matters into my own hands and go to the local RV Store near Young Harris, Ga and get parts. The owner there was not to flattering on the type of hoses and connectors I described, but did have a brass inline connector and a couple of clamps that I figured I could to a temporary repair by disconnecting the two active connections and hooking them together. The other one, which is the bypass had to stay connected to the valve. I brought them back to the campsite and did that, which worked fine. I then called Heartland and talked to Eric, who said he would send a valve out to us, which would have the "L" connectors already on it. While I had the panel off, I checked all other connections that I could see and found several were not tight, so of course I tightened them all. I would recommend that as a part of routine mtc. to take this panel off and check connections. One note: The screws on the right side of the panel are screwed in from the back side. Remove all others and pry gently to get the others to release. Be careful not to cut yourself (like I did) on the screws sticking out.
