Stop hauling hand pumps or draining your fresh water tank every fall. The Camco 36543 Pump Converter Kit mounts permanently to your existing 12V water pump and lets you siphon RV-safe antifreeze directly from a bottle -- through the pump, through every line -- without ever touching your fresh tank. One installation, adjustable wrench only, seasons of effortless winterizing.
Traditional winterizing means either dumping gallons of antifreeze into the fresh water tank (and flushing it all out in spring) or hand-pumping antifreeze line by line -- slow, messy, and inconsistent. The Camco 36543 takes a smarter approach: the included 3-way brass valve tees into the pump inlet and diverts suction from your fresh water tank to a 32-inch clear siphon hose that drops directly into a jug of RV antifreeze.
Flip the valve, run each faucet until you see pink, flip back. That is the entire process, every year, with no re-installation and no extra tools. The female-to-female pump adapter means it works with standard 1/2-inch barb pump inlets found on the vast majority of RV demand-pump installations.
Mounts permanently at the pump inlet. No seasonal reinstallation -- just flip the valve each fall and spring.
The 3-way valve bypasses the fresh water tank entirely, so antifreeze never enters your tank or tank plumbing.
Solid brass 3-way valve handles repeated seasonal use and resists corrosion from antifreeze contact.
Your existing 12V demand pump does all the work -- consistent pressure ensures antifreeze reaches every fixture and trap.
The kit installs at the inlet side of your RV water pump -- the side that normally pulls from your fresh water tank. The brass 3-way tee fitting splits that inlet so you can select either the tank (normal operation) or the siphon hose (winterizing mode). In winterizing mode, drop the 32-inch clear hose into a bottle of RV antifreeze, turn on the pump, and open fixtures one at a time until you see antifreeze. The clear hose lets you monitor the antifreeze level in the bottle so you don't run dry mid-process.
Installation requires only an adjustable wrench and typically takes 15 to 30 minutes. General steps:
