OK. Another project I completed. My ac condensation drain that runs down under garage floor and out by the ac unit was pretty much plugged up. I first tried my garden hose attachment that I made up. But, the y-tee was too close to the top and was back flowing up towards the A coil drain box and wouldn’t build up enough pressure to blow out the drain line.
I cut out section of the drain, Installed shut off valve and the Y-Fitting below the cut off valve. Now when I hooked up the garden hose I got full 60 or PSI from city water pressure. This blew out all sorts of crud that built up over 13 years or so period since the house was built.
I simply turn the cut off vale to closed, remove the plug in the y-fitting, install the hose adapter, connect the water hose and turn it on. Go to ac unit where the drain located and watch flow blasting out. Go back turn the water off, open the cut off valve, remove hose and adapter, install the y-fitting plug. Works like champ!
