Why would my water heater not heat up like it use to? The burner comes on normally and the water is warm. It use to be where you couldn't keep your hand under running hot water. Any suggestions?
I know what you mean! All valves are open. I've never changed them since I purchased my trailer that's why I'm wondering why it's not hot like it use to.
You have 3 valves, you need to close the middle valve. That will force water through the heater.
Go to the top of the page and click albums. Go into Grandview Trailer Sales album and you will see a picture of the back of a water heater. You should see something similar on your trailer.
