Uniweld 40061 Sludge Blaster

Works great on 3/4 inch condensate drain lines. I use a CO2 or nitrogen bottle with an a/c charging hose. You MUST use a regulator turned down to under 100 psi and you MUST insert tool at least 3 inches into drain line. If the pressure is too high the tool will pop out and blow up. If all of the rubber end and then some is not inserted into the drain line the tool will blow up. Follow these rules and it will clear drains for many years.

I use this almost daily through the summer on maintenances and service calls for A/C fits down a 3/4 drain perfectly and clears them out easy.

Blows out drain lines really good

Sludge getter

this item is what the ac man suggested. it works great on cleaning the sludge clogged drain pipe from our furnace/ac unit in the garage. IMPORTANT NOTE - make sure you don't use too much pressure because it will destroy your pipes - literally. I know it is less than 100 pounds of pressure but I think probably closer to 60 to 80 tops.

THIS ITEM IS FOR EVERY TECH TO MAKE EASY MONEY

Blew a hole in the side the first time I used it. Was inserted properly.

Just bought a second one after the last one broke, lasted 3 years cleaning 1 to 5 drain lines a day during the summer.
