Camco RV & Boat Pump Winterizing Kit — Brass 3-Way Valve, 1/2"-14 NPT/NPSM Adapters, Permanent Install

The Camco Permanent Pump Converter Winterizing Kit is an in-line brass valve and adapter set that lets you use your RV or boat water pump to circulate antifreeze through plumbing for dependable winter protection.

Preparing an RV or boat for freezing weather is easier when you can push antifreeze through fixtures using the vehicle’s existing pump. This compact kit includes a brass 3-way valve, siphon tube, two pump adapters and Teflon tape to create a durable, leak-resistant connection. It installs permanently on compatible pumps with 1/2"-14 NPT or NPSM ports so you can winterize quickly every season without repeat teardown.

How does this kit let my pump circulate antifreeze?

Install the brass 3-way valve and the matching pump adapter to route antifreeze from a siphon hose into the inlet or outlet of your pump. The valve directs flow so the pump draws antifreeze instead of household water, moving it through supply lines, faucets and fixtures for full-system coverage.

• Brass 3-way valve controls antifreeze routing
• Siphon tube feeds antifreeze from a container into the pump
• Two pump adapters fit common 1/2"-14 NPT/NPSM ports
• Teflon tape included for leak-proof threads

Will it fit my RV or boat water pump?

This kit is designed for pumps with 1/2"-14 NPT or NPSM threaded ports, which covers a wide range of RV and marine water pumps. The included adapters simplify installation; use an adjustable wrench to make a secure, permanent fit.

• Compatible with standard 1/2"-14 NPT/NPSM pump ports
• Permanent installation avoids annual reassembly
• Works with Camco water heater by-pass kits to save antifreeze

How do I install and use the converter safely?

Installation is straightforward: mount the valve and adapter to the pump port, wrap threads with the supplied Teflon tape, and attach the siphon tube into a container of non-toxic RV/marine antifreeze. Operate the pump briefly to push antifreeze through all fixtures until protected, then close the valve when finished.

• Required tools: adjustable wrench; pump not included
• Use only RV/marine-safe antifreeze per manufacturer instructions
• Pair with a water heater by-pass kit to reduce antifreeze use

What certifications and durability features does it offer?

The valve is brass for long-term corrosion resistance and the connectors are designed for repeated seasonal use. This product meets federal and state low-lead requirements and carries CSA Low Lead Content Certification to NSF/ANSI 372 for peace of mind around potable-water systems.

• Durable brass construction resists corrosion
• CSA Low Lead Content Certified to NSF/ANSI 372
• Engineered for permanent, year-round mounting

Who is this for: Owners of boats, RVs or camper vans who want a faster, cleaner winterization method without relying on manual hand pumps or repeated plumbing disassembly. This kit suits DIYers who prefer a permanent, tool-friendly solution and those looking to conserve antifreeze by combining the converter with a water heater by-pass kit. Note: the unit uses your existing water pump (pump sold separately) and works best with non-toxic RV/marine antifreeze and the recommended by-pass accessories for maximum efficiency.
