A couple of days ago I noticed some dripping coming from our a/c's secondary drain line. I checked in the attic, and there was a little bit of water in the drain pan, but the level was way below the shutoff switch trigger point. Still, I figure I ought to try blowing out the primary line to avoid any potential issues down the line as we have had some nasty clogs in there before that lead to water backing up in our bathroom sink.
The last time we had a a/c guy come work on a clog, he installed this valve in the primary line:
My research tells me this is a Searco QB1 blowout isolation valve. I get the idea of it: closing the valve, then hooking a compressed gas source to the downstream side to blow out the line. I'm hitting a snag though figuring out what all I'll need in terms of hardware to connect into the side tap.
It looks like an oversized Schrader valve from what I can tell, so probably some sort of specialized end fitting would be needed on a hose. Not really sure tbh since I've never done any sort of a/c work on my own. Has anyone had any experience tying into one of these and has a good idea of what all parts would be needed?
