Drain King 750 Unclogs Main Drain & Sewer Line with Water Power, 3 to 6 Inch

I have a 6 inch diameter cast iron 200 foot long sewer line that I cleared two years ago with a sectional sewer cleaning machine. At that time, there was only a minor amount of roots and the obstruction was primarily cause by non-flushable paper products. When the sewer line got obstructed this time, I thought to give this product a try. I was skeptical that this product would actually work, but the thought of getting a 300 lb sectional cleaning machine and all the rods into the basement motivated me to give it a chance. I used a 25 foot inexpensive garden hose that I connected to the main water line and fed the Drain King about 10 feet into the main line through a cleaning access. I have city water and so the pressure was very good (not sure if it was really 80 psi like the product literature said should be used, but it was definitely 60 psi). It made a humming noise when I turned on the water and I let it run for maybe 20 minutes. Afterwards, I checked the water flow and it was as good as after I cleared it two years ago! I could barely believe it, this thing actually cleared my sewer line! Thank you Drain King!

Excellent device.Unblocked my kitchen drain after 30 minutes use. I had previously tried using a plunger,various chemical unblockers, and a power hose drain unblocker to no avail. And its simple to use. Screw on garden hose, push this device into the drain then turn on the hose.

We've had some problem with the sewers backing up ever since we moved in 5 years ago. Turns out we have a dip in the pipes where "stuff" collects, causing a blockage. I paid the plumbers a few hundred dollars a couple of times to clean it out, and then I tried doing it myself by renting a big 100 ft toilet auger (75 ft was too short). It was a PAIN! Huge drum thing that spin and you have to feed it down while it's spinning and get it all the way down to the blockage. Cheaper than the plumber but a almost a full-day affair with driving it to and from the tool rental. Then I found out about the existence of these sewer bladders. First I tried a cheap one from the local hardware store, but it didn't work, which I think was because the nozzle at the front was all rubber and just had a little hole in it. It wouldn't fill up by the water pressure alone, so it was basically useless. I did some more research and found this Drain King which has a proper metal pressure valve at the front, and it also pulses the water for more "dislodging" effect. It cleans the blockage better than the snakes/augers, where you basically just poke the stuff instead of pushing all of it evenly. And I don't have to push it down the 90 ft or whatever to the blockage, I just have to feed it in about 20 ft from the clean-out to where there are no more splits in the pipes to the blockage. Done in under an hour! It's LITERALLY the perfect solution to my problem. And it's cheaper and provides better results than the other solutions! NOTE: you are not supposed to push this into the blockage, you're only supposed to use the water pressure to clear the blockage. You stick it down the pipe deflated, you turn the water on causing the bladder to expand to create a seal in the pipe, and then it fills the pipe area between the bladder and the blockage with water. This pressure will then push on the blockage until the blockage gives way and the water carries the debris down the sewers. I let it run for quite a bit as I was watching the sewer end. I noticed the debris coming in "waves", so don't stop after the first one with the debris. Wait until there is clear water coming through and you can be sure you got it all.
