Hot water???

We are newbbies to the RV world. I had our coach, 1999 Rexhall, winterized and now we are in Memphis, TN. where it is much warmer than Chicago area.
My wife wanted hot water yesterday to wash dishes. I have never been through a winter / summer cycle so I am sure that I have missed something.

This is where I need your help. We have about 10 to 20 seconds of hot water.

Any ideas what I need to do to get the 6 or so gallons of hot water we had last summer?

Any help would be much appreciated.

Take the outside cover off the WH and make sure the drain plug/anode has been installed and the pressure relief valve shut. Then you'll have to look for the WH bypass valve(s) and make sure they are set for normal use. You might have just one valve and a couple of check valves, or a 3 valve system like the one pictured.

In this photo, all 3 valves are in the open position, which isn't what you need for normal use. The center by-pass valve should be set with the handle 'across' the hose in the off position. Winterize position would be the upper and lower valves shut, the center valve open.

Follow the info the last post. You should find the bypass valves just to the left and at the back of the water heater in your Aerbus. The little hot water you are getting is the warming of the water near the heater.
