3" - 4" Drains

I didn't expect too much from a 20 dollar product. I had a really bad clog in my mainline. I had water backing up in my downstairs shower and toilet. I tried a bunch of different liquid drain uncloggers first, then I was gunna rent a mainline snake from home depot, but decided to try this first. This thing worked wonders. I had the mainline unclogged within 10 minutes. Great product.

Last year the main line backed up and I paid over $700 + the mess of cleaning up the inside overflow …YUCK! This time I had a better idea of the issues that happen before the full back up happens. Flushing the toilet and then bubbling in the toilet and slow drainage in the tub. Then waste coming up in the shower/tub when flushing the toilet is the last line of defense before it’s all over your floors! So this time I watched some videos and stumbled across this item. Seemed reasonable enough if you kinda understand what’s happening. Something clogs the mainline (toilet paper, toys, or even roots) and all you need is an enough pressure to push it out of the way. Now it could be a major issue like a collapsed pipe, but if you just need to push the junk down the pipe, THIS WILL DO THE TRICK! (The first thing I did try was some chemicals that should have eroded the junk, but that didn’t work for me. That was about $100) After some research, I went with this brand. A lot of people advised not to go with other brands. I hooked it up to the hose line and you have to push it down just enough to seal off where water doesn’t overflow on the ground, but also so that it doesn’t blow back into the house. It’s not far, but look at some videos on this (if you don’t push it far enough it will either not work or make a larger mess). The first time I tried it (I was a little scared), I turned the water on for 5 mins but it wasn’t sealed so it didn’t work. It wasn’t far enough in the pipe or maybe was in an area where it didn’t fill the pipe all the way. The second time I did it, I pushed it a little further, this time I knew it wouldn’t blow back into the house so I was less scared. It made a seal so that the water didn’t come out the top of the pipe onto the ground. I ran the water for 10 mins. When I turned the water off, I heard a big suction sound and that’s what you are waiting for. The blockage was pushed out and you are back to normal. They say that you should run the hose a little longer just to make sure the junk is pushed all the way down the line. Some lines of 100ft or more. Anyway, this was a $21 solution. I know I saved myself hundreds of dollars and the headache of having to call a plumber. Now I have what I need in the event that this were to happen again. Hope this helps you!

Just started to use this today on my outside rain drainage system. So far it worked great sofar

Great invention. Expands inside pipe with water pressure. Should clear local obstructions. Don't expect to clear tree roots or large amounts of debris such as a large amount of soil that has infiltrated a pipe. Expected to work well for routine maintenance flushing. Bought for using on 4" property drainage line. Update-- Stored indoors in plastic bag to help preserve it. Used about 3x since 2014 purchase. Went to use it 4th time, (11 years old, 2025) and heard a large 'pop' from the pipe. It blew out the bladder -- catastrophic failure. Photos show damage. The rubber is very thick. Expected to get more usage from it. Probably needs super formula to last longer. Ended up buying a 2nd one, since it is a valuable tool. If you run into a blockage that cannot be cleared, mark the location on your hose. You then know how far from entrance point that the blockage occurs, and can focus on that area for repair.

Update: After using this several times, I've come to see this as a miracle product. It works better than a drain auger being run by a professional plumber. If the problem is a solid ball of roots, this wouldn't work, but anything less substantial and it knocks it out. Today, this let me dislodge a flushed object (pullup? ball of baby wipes?) that was clogging my main sewer line so badly that sewage backed up into my showers. It has paid for itself many times over - and doesn't charge extra for work on weekends! ******** Tried before using a 100' drain auger, but it couldn't clear the clog. Then did the auger. It also didn't clear the clog. Tried the Drain King again with a longer hose, had to let it work a while and let the water drain a couple times, but it finally did the job. For the money and ease of use, I will be using this every time before trying the auger. Warning: the water has to go somewhere. That's probably going to be a bathtub or sink. Have people watching so you know when to stop or you'll have sewage on the floor.

I had lost track of an old corrugated downspout line a few feet from the downspout, and this Drain King helped me find it again. I put the Drain King in the downhill side and was able to slide it in at least 6-7 feet. Turned it on, and immediately noticed a loud hum and vibration that helped me locate where under the grass the line was running. And it made enough of a seal where it filled up the pipe and I was able to find the lost end on the uphill side. Not a big slope, but still - this was golden for my DIY project. From here I can snake out the old pipe and replace just the missing section. This was perfect!

Cheaper than any chemical and it is incredibly easy to use. Spent Hundreds on plumbers and equipment and this 20$ item cleared it when all hope was lost with near zero effort. Keep one on hand even if you do not need yet RECOMMENDED! FYI my issue was a FULL CLOG on the MAIN sewer line that was at the LEAST 100ft away from the clean out, hose only needed to be in a few feet and ran for about 40min.

This device is great at clearing drains etc

Por fin pude destapar mi drenaje, que la constructora (Ruba) dejó con material el tubo de 4” con una brida de 3”, lo había tratado de desatascar con uno de resorte truper, pero se destapaba parcialmente, ya que solo movía las obstrucciones, pero como continuaban, al poco tiempo se volvía a tapar, usé este y se empezó a escuchar un golpeteo en el drenaje que iba bajando de intensidad hasta que se escuchó que el agua salía libre, ahora en el tubo horizontal se queda 0.5cm de ancho de agua, ya podré poner nuevamente mi taza

Item delivered is as described

This is the second one I have bought. this one is build a lot heavier than the old one I had. It works great. I recommend this product

Thank you for the delivery. Item is what I was looking for a I am happy with it. Regards, Victor Handlir
