The Camco Camper/RV Water Heater By-Pass Kit is designed to streamline the process of winterizing your RV, motor home, or travel trailer. It helps save between 6-10 gallons of antifreeze by allowing you to bypass the water heater, offering a significant cost-saving feature. The kit is compatible with 6-gallon RV water heater tanks and includes fittings with a 1/2-inch -14 NPT thread size, ensuring a fit for most RV setups.

Installation is intended to be permanent, meaning you won't need to disconnect and reconnect components each time you winterize, adding to its ease of use and convenience. The kit includes an 8-inch nylon reinforced hose that is crimp-resilient, two 3-way brass valves with shutoffs, and a roll of Teflon tape, providing everything needed for installation. The brass valves are particularly notable for their durability and non-restrictive flow, which is ideal for long-term use.

The valve handles feature flow indication, offering a visual cue to ensure proper operation, enhancing user-friendliness. If you're looking for a permanent, cost-saving solution for winterizing your RV, this kit could be a valuable investment.

The TOPRING 45 PSI Air Compressor Water Blow Out Adapter is a handy tool for winterizing your RV, camper, boat, garden hose, and sprinklers.

The high-flow fittings ensure uninterrupted antifreeze flow, which helps improve engine performance and reliable operation. This kit is particularly beneficial for boaters and RV owners looking to safeguard their engines during the off-season, though separate antifreeze, motor muffs, or pump adapters are needed for optimal use, which are not included in the kit.
