Camco 36133 RV Water System Blow Out Plug Black Plastic with Schrader Valve

Item Description

Camco Plastic Blow Out Plug is used to apply air pressure to your water lines to ensure that all of the water is removed before winterizing. With less water remaining in the lines, your anti-freeze will work at the dilution you want. Just screw the plug into the city water inlet, open all drains and faucets, attach and activate the oil-less air compressor until all lines are clear. Durable plastic construction will not rust.
