48" Flexible Long Sink Drain Tool, AC Drain Line Cleaner Tool, Remove AC Clogging, Sink Clog Remover Cleaner Brush, Flexible Unclogger for Cleaning Sinks Food Debris, Build Up by FryOilSaver Co. B313C

Pretty good for small diameter drain pipe clearing and cleaning . Stiff enough to push through moderate blockages!

The tube under my sink that drains the dishwasher had all this really disgusting dark gunk in it (apparently I need a “high loop”?). I had tried to clean it out with a bunch of (chemical) stuff as I couldn’t reach into it to manually scrub it out. Nothing touched the gunk at all. I mean, I’d filled it with peroxide and left it overnight - no effect. I’d done the same with citric acid, thinking it might be hard-water buildup. No effect. Tired of the stank in my dishwasher, I bought the brush.Today, finally, it arrived, and I immediately got to work. It was a tight squeeze to get it in (that’s what she said) and even harder for some reason on the way back out (hehe) but the gunk came out with it. It smelled terrible - kinda like my dishes have smelled after being “cleaned” in the dishwasher - and is surely the source of the funky smell on my dishes for the last 2 years.YAY for super specific cleaning accessories!

It has been a great addition to my toolkit. The build quality is good—it's sturdy and durable, . The 48-inch length is perfect for reaching deep into drains, and it’s flexible enough to navigate around 45-degree bends and p traps with ease. However, it will strugglewith 90-degree turns, so keep that in mind if your drain has sharp angles, might need to order a smaller brush. Overall, it’s an excellent tool for most drain-cleaning tasks.

A little thinner than expected but works as designed.

Gave it three stars because although it did not work for clearing my a/c drain line (a 90 degree turn from the entrance), it probably will work for sink drains. I will keep it for such use.

The flexible brush worked great to unclog my bathroom sink

I bought to rental properties both of town and the A/C installation left something to be desired. The double safety T’s were installed right on top of one another and condensation line was almost a complete 180 back up into the T’s . Compressed air was good but the 180 trap was never completely clean. This was flexible enough and long enough to push anything in the line out far enough that I could blow it out from the vent line.

My dishwasher was spitting water out of the sink air gap, which led to a secondary problem of water leaking through the air gap counter hole into the bottom of my sink.I saw some advice on YT to take a paper towel and place it over the [opened] air gap and blow so air pressure could clear debris. I did, and sure enough some stuff came out (yay!). Unfortunately, the water-thru-air gap problem persisted.I then took part the tube connected to my disposal to make sure the plug (forget the name) was probably poked through the hole. What I discovered was nasty...the black tube was full of sludge. Ugh.I put everything back together, took this pipe cleaner, and ran it through 3 or so times. I then tested to see if the hole/tube was cleared by tilting the sink shower head, turning on the hot water, and letting it run through that hole. It was a good test because the first two times I cleaned with this tool, water would build up and not drain through properly. Third or forth time did the trick!tl;dr• it fit my kitchen sink air gap hole (which leads to disposal)• run it through a few times to get the grime out• have paper towels handy and use it to shield dirt from splashing everywhere when the bristle comesback out• test tube path by running hot water down it after each use of the tool
