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 Matthew Marquez

I have a small underground sprinkler system for our beds, maybe 10ft by 40ft. I use my smaller air compressor to blow them out in the fall. I always connected the connectors to the hoses and taped them, but there were always air leaks and it hurt. I finally found this and it makes things a lot easier. The on/off valve is very good and easy to use, but I get very little air leaks from it, but it's not enough to worry about.
