What is the Best RV Winterizing Kit?

It is never a great feeling when it dawns on you that the camping season is coming to an end. This comes with a responsibility to put things in order and ensure that the camper will be ready next time you need it.

A huge aspect of winterizing your RV involves ensuring that the water supply system is protected.  Exposure to freezing weather can cause some serious damage.

The Camco 36543 is an incredibly affordable pump converter that allows RV owners to bypass the main water supply line and use the water pump to fill the lines with anti-freeze. The kit comes with all the tools needed for a successful installation. In this post, we discuss why the Camco 36543 is a good purchase and how you can use it to winterize your RV.

How To: RV Winterizing Kit Installation Instructions

To begin installation of the Camco 36543 pump converter kit, you need to first disconnect the incoming fresh water pipeline from the pump. Later, attach the three-way brass valve to the suction opening on the pump. If necessary, you may use the sealed female/female adapter.

When tightening refrain from grasping the valve handle with a wrench as it may damage the valve’s interior seal. Once done, connect the waterline to the opposite end of the three-way brass valve.  You may check for leaks or begin operation, turn the handle to open position.

How To: Winterize your RV Water Lines

The next step after installing the Camco Pump Converter is to start wintering the water lines. Begin by draining all water in the RV pipe system. This includes the holding tank (black and grey water) and the hot water heater. For this step it is wise to follow your RV’s manufacturer’s step.

Later remove the 3-way valve cap and attach the clear vinyl siphon hose and tighten by hand. Place the opposite end of the siphon hose into your fresh water system antifreeze. Turn the valve’s handle to the by-pass position.

Turn on individual faucet sequentially to allow the antifreeze to flow through. A cup flow into the drain would be enough to protect the traps. Once all the antifreeze is drawn from the container, turn off the pump, detach the siphon hose from the valve and replace it with the cap. Lastly turn the valve’s handle back to open position.
