Review: DIY Plumbing Help--A+! - 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 desertcart and searches at Google and YouTube can teach you how!

## Questions & Answers

**Q: is it big enough to clean out the main sewer line under the house running to the sewer**
A: depends on the water pressure and pipe size less than 4 inch.but it worth a try

**Q: How long to leave it in the pipe?**
A: When the flow reaches maximum and stays for a few minutes, then remove it.

**Q: Is this designed to work on a toilet also?**
A: These are not made to be used inside a toilet, 
the only way to use a drain king for toilet drain is to remove the toilet itself, then insert a drain king in the actual pipe under the toilet.

**Q: Can this be used to clear a pvc - ac condensation drain line?**
A: Save your money. It busted the first time I used it. Made of cheap rubber and won't hold up to the pressure necessary to clear the line. You can find better quality for same price at Lowes or Home Depot.

### ⭐⭐⭐⭐⭐ Works as it's supposed to

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.

### ⭐⭐⭐⭐ Lifesaver, but it blew up after clearing the drain.
*by B***Y on August 30, 2023*

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.
