Camco Blow Out Plug - Plastic - Screws Into Water Inlet

The Camco Blow Out Plug is an essential winterization and maintenance tool for boat and RV owners who depend on reliable freshwater systems. When temperatures drop or seasonal storage approaches, leaving water trapped in supply lines invites freeze damage, corrosion, and costly repairs. This plastic blow-out plug screws directly into your water inlet, creating a sealed connection point that allows compressed air to push all standing water from your plumbing network in minutes—protecting your investment year-round.

The design is straightforward but proven: thread the plug into the city water inlet fitting, open all drains and faucets throughout the system, then connect a standard air pump or compressor and activate it until water stops flowing from the lowest outlets. The durable plastic construction resists corrosion from saltwater spray and freshwater minerals, ensuring the threads remain tight season after season. This method is far safer and more effective than relying on gravity alone, since it reaches every low point in your lines—preventing ice formation that could crack tanks or fittings and cause leaks when you're back on the water.

Anglers and boaters in cold climates, snowbirds storing vessels over winter, and RV enthusiasts preparing rigs for long-term parking all rely on blow-out plugs as part of their winterization checklist. The compact, lightweight design fits easily into any maintenance kit, and the standard water inlet thread size ensures compatibility with most modern boats and recreational vehicles. Installation takes seconds; the protection it provides lasts a lifetime of use. For anyone serious about preserving their vessel's freshwater system, the Camco Blow Out Plug is an affordable safeguard that pays dividends in peace of mind and avoided repair bills.
