Re: Result of AC drip pan overflow -- cracked ceiling

said by disy:

Use a gallo gun

I had to look this up!

I have an air compressor and a portable air tank but haven't used it with my drain lines because...the installer put my Tee in-line AFTER the P-trap (where a clog would normally reside) and applying compressed air would then (wouldn't it) blow the mold/mildew/algae/crapola back-in to the A-coil housing.

Do y'all's drain lines always have the access port (Tee, for pouring in liquid I presume) BEFORE the p-trap?

I honestly do not know tee trap from p trap - sorry - I use the gallo gun because it has the perfect size nozzle to fit the drain pipe in the AC unit and I blow it out versus, blowing it in - not sure if this makes sense or not - also the gun is just a quick blast of air versus a compressor, which i think could be too much pressure on the piping
