.75" - 1.5" Drains

This funny looking device is a priceless help to anyone needing to clear an Air Conditioner Drain. You didn't know your Air Conditioner even HAD a drain? Good for you. I just learned that they DO, after carpet in our hallway got wet. Wet carpet? From what? Tracing the puddle back to its source, I got a quick education on something your A/C Technician already knows about. Somewhere, under the whole house air conditioner unit (you'll probably find this behemoth in a utility closet in your hallway), there is something called a "drain pan." This drain pan catches the moisture that evaporates out of the cooling mechanism for an air conditioner, called an Evaporator Coil. Condensed moisture drains off this evaporator coil and into the drain pan, which actually has plumbing attached to drain the excess water collected into it and out of your house. UNTIL IT BACKS UP. Then, you get a puddle on the floor, like I did. THIS IS HOW YOU FIX THAT PROBLEM. Your A/C drain can get plugged up with either 1. Algae or 2. Calcification/Mineralization or 3. Both. You can knock out the algae by pouring a little bleachwater into your drain. I've since learned most A/C people recommend you treat your drain this way about every 6 months. That's what they charge you to do, when they "flush your system." If you have more minerals than algae, you need to use a little CLR Jelmar CL-4 CLR 128-oz. Calcium, Lime & Rust Remover to dissolve the minerals in the PVC drain, then rinse with water. It's best to then fully clear the drain with a device like this. The way we fixed ours was: a little bleachwater (which didn't clear the blockage), added a bit at a time till the drain worked a bit (this is added directly into the PVC drain, NOT into the A/C's drain pan). Realizing that algae wasn't the root cause of our drain blockage, we waited for the bleach to clear, rinsed the drain slowly, then added 1/4 cup of CLR, which opened the drain further. Once it was draining a bit, we bought this, added a bit of CLR again, waited 10 minutes, then inserted this little device fully into the PVC pipe (after screwing a water hose onto the end), then turned on the water to finish "cleaning" the drain. (Just a note: in our case, the PVC drain has TWO inlets/access points. We blocked the lower one's 90 degree coupling (which feeds back into the A/C unit drain pan) with a stuffed rag temporarily during this procedure, just to prevent any possible backflushing--look at your own setup & you'll see what I mean. Alternatively, you could use this device in that drain inlet, as well, as long as it's long enough to totally block that 90 degree coupling; I'd still advise using a rag or PVC plug to temporarily plug the other inlet, just as backflushing insurance). It worked like a champ; the water flowing out of the hose works to "swell" the rubbery part of this device; while allowing water to flow through it, it doesn't allow any water to 'back up" through the drain. This increased water pressure helps "blow out" any remaining debris plugging the drain. Problem solved! It works great, is easy to use, and does the job with ease. MUCH better and more efficient than just trying to block a water hose with a rag or other leaky, messy solution. This was a quick & easy fix for our A/C drain; highly recommended for quality, utility & value! FYI UPDATE 8-27-15: Just a reminder: two other possible causes of A/C leaks are 1. Dirty Filter 2. Clog in drainpan. A dirty filter is fixed by changing it (see Owner's Manual for your AC). Clogs in drainpans can be prevented by using acid tablets in the drain pan, usually done by an AC technician. DIY options for these are available at Amazon and searches at Google and YouTube can teach you how!

Works as it's supposed to. I used it to unclogged our whole house ac drain. Cleared it in a few seconds and so much gunk came out. I can also use this for bathroom sinks because it is the right size for it.

I used the small one to clear a clog in a sewer check valve. In the past, I’ve had to disassemble the valve in the vault which is 3-4ft down and an absolute pain, not to mention messy. This worked like charm when dropped down the nearby clean out. I could only fit the smaller one around the right angle needed, but it was big enough. It cleared the clog in 1 minute. But after the clog cleared I ran it one more time just to double check, and this time it did not release any water and then the balloon popped! A chunk of rubber is lost down the drain, but probably small enough to have washed out. I’m glad I got it but am disappointed it only worked once. Still worth it, given the other options.

I use this when my AC line clogs, works well to unclog the line But can not turn the water pressure up to fast or it will bubble

I tried everything to clear my A/C drain from chlorine and acid to snakes and hose and wet vacuum. This finally worked and was easy to use.

I used various chemicals and my shop vac, sucking and blowing on my clogged condensate line. After several attempts, water would flow ... only to have it clog again in 2-3 weeks. Even had an A/C tech work on it, only to have it clog again. When I compared this Drain King to the condensate access, it is too long to fit inside, so I didn't think it would work. Plus, the nearest spigot for a hose was 60 feet away = how could an assistant control the pressure at the valve while I held it in place? Fully frustrated, I decided to give it a try. Purchased a shut off valve and assembled Drain King to shut off valve to the hose. Had assistant turn on water while I maintained the shut off valve closed. NOTE: Had to be very careful with the shut off valve because having most of the Drain King exposed meant it would be easy to burst the bellows! I.E., open the shut off slowly to effect a seal and start the hydraulic process. In the end, about a foot of grey-white gunk was forced out of the condensate line - assistant at first thought it was a snake! Be sure to have something (towels?) at the ready because there will be leakage. I am now A/C-ing happily ever after. Previously, I looked into C02 guns, but each time used it exhausts a cartridge. Since I'd already expended a great deal of effort without success, I was concerned it would be wasted money. Plus, if the C02 blast ruptured the pipe under the house, it would be an expensive fix.

This says it will clear a 3/4" drain. Well, The black rubber part fits inside the 3/4" pipe, but the hose coupling is too big to fit down into a 3/4" pipe. So, if you need to clear a clog further down into the pipe, like past a joint where other pipes connect, then you will not be able to get past that area to clear the clog. The product seems like it will work on larger diameter pipe, but it will not work into a 3/4" pipe except at the very top of the pipe.

this probably works well if you have a clog in the drain or p trap. my clog was in the wall, tried removing trap and placing right in pipe, I think the pressurized water was going up the vent instead of down the pipe. I was not going to climb up on my roof to blow it out from there (i also bought a larger size) This small size only fits in the drain in the sink. I was able to get rid of the clog in minutes with sulphuric acid, that stuff is amazing but you must take precaution because of the explosive nature of chemical... remember "acid to water, that's the order, water to acid you might get blasted" never use the acid if you have standing water in sink, ok in p trap. three star only because it didn't work for me.

It break immediately !

El producto resolvió el problema, no es que a la primera destape, después de varios intentos quedo resuelto, me gustó mucho por que el plomero me había comentado que iba a tener que abrir mi pared y piso para poder destapar, ya que con ni el ácido muriatico ni con la herramienta que él había introducido ,se logró destapar. Lo hice yo misma , no fue nada complicado.

Es kann nur ein Teil zurückgeschickt werden da ich das zweite Teil nicht bekommen habe

This item solved a long standing issue I've had with a blocked 3 inch garden drain (with a 90 degree elbow). I was afraid it would fall apart after a few uses, but I've reused it around 25 times on the same pipe because it had construction debris clogging it, and finally I managed to get a good degree of flow happening! So it's durable, and does the job perfectly, I don't know why some reviews suggest otherwise, misuse perhaps?
