Clean Water Heater
Have 2004 Tioga 26Q, Atwood water heater. Have watched You Tube videos about dumping water, squirting inside with wand, draining, and filling tank with white vinegar and water to remove "scale". I do...

Learned some things about Atwood 6 gallon water heaters, there are 1/2 inch and 3/4 inch size temp and pressure (T&P) pop off valves. My 2004 rig uses the 1/2 inch size, after 2005 versions use the 3/4 inch size. The valves are somewhat awkward to remove. Camco sells a removal tool #10552 that fits over the valve and makes removal easier. Large water pump pliers (may) work after you remove the sheet metal cover that's in the way. CW and Amazon sell Camco replacement T&P valves. Cheaper standard T&P valves from Home Depot will fit, must be rated for 150 psi and 210 degrees temperature. After reinstalling the T&P valve, let tank fill with valve lever open until water runs out, then turn off pump and shut the valve. This sets the air gap in the tank and stops water flowing out of the T&P valve if it is working properly. If valve is not closing properly, repeatedly flipping the lever open and closed may dislodge foreign matter that may be keeping the valve from sealing. A little leaking from the valve is normal. Like many things in RV's, water heaters are not designed for easy DIY maintenance.
