Winterizing your RV water heater or swapping a corroded drain plug is a lot easier when you have the right tool for the job. The Camco 11633 kit gives you an angled plug wrench sized for the tight compartments most RV water heaters live in, two replacement 1/2" drain plugs, and Teflon tape to seal them properly -- all in one package. No trips back to the parts store mid-job.
Most RV water heaters are tucked into a pass-through bay or a tight exterior compartment, leaving almost no room to swing a standard socket or box wrench. Camco designed the 11633 wrench with an angled head specifically to reach into those confined spaces and break free a stuck or corroded drain plug without skinning your knuckles or stripping the plug.
The wrench's prong-style tip is also effective on petcock-style drain valves and anode rods that have a petcock integrated into the rod -- common on Suburban and Atwood/Camco water heaters. If the plug is rusted or seized, the prongs give you more bite than a smooth socket would.
Reaches past cabinet framing and baffles in tight RV water heater bays where a straight tool won't fit.
Grips standard drain plugs and petcock anode rods, including corroded or slightly damaged plug heads.
Works with both 7/8" and 15/16" drain plug openings -- the two most common sizes across RV water heater brands.
Includes two 1/2" drain plugs and Teflon tape so you can replace the plug and seal it in the same session.
Camco includes every component you need for a complete drain plug service:
Drain plugs on RV water heaters are exposed to repeated heating cycles, mineral deposits, and seasonal freezing. Camco recommends replacing the drain plug every year during your annual winterization or de-winterization service. The two plugs included in this kit give you one for right now and one spare for next season.
This kit is a practical fit for any RV owner who performs their own seasonal maintenance. Typical uses include:
Many Suburban water heaters use a combination anode rod with a petcock drain built into the center. The prong tip on this wrench engages the petcock tabs directly, making it useful for removal even when the rod is corroded. Atwood (now Camco) water heaters typically use a straight drain plug without an anode rod -- this wrench handles those as well.
Wrap 2-3 layers of Teflon tape clockwise around the plug threads before reinstalling. This ensures a leak-free seal and makes future removal easier. Do not over-tighten -- snug by hand, then a quarter to half turn with the wrench is typically sufficient for a water-tight seal on a plastic or aluminum tank boss.
After draining, inspect the tank boss (the threaded fitting in the water heater tank) for cracks or corrosion before reinstalling any plug. A damaged tank boss can cause leaks even with a perfect plug and fresh Teflon tape. If you see white mineral buildup, flush the threads with white vinegar before reseating the new plug.
Always turn off the water heater and allow the tank to cool completely before removing the drain plug. Opening a pressurized, hot water heater can cause burns. Turn off the LP gas or electric heating element, then allow at least 30-60 minutes of cooling time before proceeding.
