Check the pressure relief valve on the water heater. At times it will "weep" water out when the heater is operating and is caused by not having an air head in the tank. To cure the problem turn the water off at the campground connection and open the pressure relief valve by lifting the handle then open a hot water faucet in the coach. When the water stops coming out of the valve the water level in the heater is at the correct level. Close the pressure relief valve and the faucet in the coach and turn your water back on. Should be OK now. I need to do this procedure every 6 months or so.
