Black plastic RV blow out plug with Schrader valve for winterizing compatible RV fresh water systems. Threads into the RV city water inlet and connects to an air compressor or tire inflator-style chuck to help clear water from plumbing lines before freezing weather.
The Camco 36133 is a plastic RV blow out plug used during winterization to help remove water from the RV fresh water plumbing lines. It screws into a compatible RV city water inlet and uses compressed air through the built-in Schrader valve to push remaining water out through open faucets, drains, and low-point lines.
Removing leftover water before storage helps reduce the risk of freeze damage and helps RV antifreeze work more effectively by limiting water dilution in the lines. The plastic construction will not rust, making it a simple seasonal tool for RV winter prep.

Rust-free plastic construction for seasonal winterizing use
Use regulated, low-pressure air only. Excessive air pressure can damage RV plumbing lines, fittings, faucets, check valves, and water heater components. Follow the RV manufacturer’s winterizing instructions and open faucets/drains as needed before applying air pressure.
Drain the water system first, screw the blow out plug into the RV city water inlet, open faucets and drains, then apply regulated compressed air through the Schrader valve until water is cleared from the lines. Many RV owners still add RV antifreeze after blowing out the lines, depending on the RV manufacturer’s recommendations and climate conditions.

Confirm your RV uses a compatible city water inlet connection and that your air compressor or inflator can connect to a Schrader valve. This is a manual blow out plug. It does not regulate compressor pressure, so a separate air pressure regulator may be needed.
The Camco 36133 is commonly used on travel trailers, fifth wheels, motorhomes, campers, toy haulers, and other RVs with compatible city water inlets. It is a simple tool for blowing out fresh water lines before freezing temperatures or before adding RV antifreeze.
The Camco 36133 is a black plastic RV blow out plug with a Schrader valve for winterizing compatible RV fresh water systems through the city water inlet. It helps remove water from plumbing lines before freezing temperatures and can help reduce RV antifreeze dilution. Verify city water inlet compatibility, air compressor connection, regulated air pressure, faucet/drain position, water heater bypass procedure, and RV manufacturer winterizing requirements before use.
