Review on 🚿 12-inch Winterize Sprinkler System, RV Motorhome Boat Camper, and Travel Trailer: Lead-Free Brass Air Compressor Quick-Connect Plug to 3/4-inch Garden Hose Faucet Blow Out Adapter Fitting with Valve by Dave Brummet

It's good that someone is making this little connecting hose so those of us trying to blow up our own sprinkler systems don't have to fix some brass monster from our local hardware store. . The check valve is a good addition. So far I've used it to blow out my sprinklers and garden hoses ahead of this weekend's frost forecast. This works pretty well. My only complaint is that the fittings that come with it leak, requiring you to unscrew them and add teflon tape to seal the leaks before using them.
