Kärcher 26377670 15 m Pipe and Drain Cleaning Kit for K2 - K7 Series Domestic Pressure Washers, Black, Yellow

When you start out with this please be patient. It works but relies on the user gently pushing in and out.The pipe is a reinforced hosepipe stiff enough to penetrate the blockage. One end has a brass bayonet fitting which fits into your Karcher jet washer gun. The other end is a brass bell end with water jets which spray backwards. This spray provides the propulsion for the pipe and bell end to rapidly move along the drain pipe.Fit the bayonet end to your turned off Karcher jet washer gun handle. I have two pressure washers, one cheaper low power and one higher pressure machine. This hose works best with higher pressure machines.Locate your blockage. With the water turned on into the Karcher but no power yet, insert the bell end into the drain to be sorted. Push the bell end in up to the red mark on the shaft.Once properly in, turn on your Karcher and let your pipe shaft go. It will speedily penetrate the drain. Keep pushing in more length until you hit the blockage. Now gently pull and push your pipe in and out until fluid levels rise and gurgling starts.Once the block has been loosened, keep pushing your bell end in and out. The water levels will suddenly rise and flow towards you. You will see the fluid and blockage disperse.Once the blockage is dealt with, the pipe will start to pull away from you. Let it go in all the way just in case a secondary blockage is present and repeat the above process.Be patient, it does work. It looks very similar to that used by the professional I had to originally call out.I found that it just didn't work with the lower powered Karcher washer. It does need some Welly.The most difficult part of this process was fitting the bayonet to the Karcher handle. Had to really push hard to get the brass bayonet fitting to securely attach itself to the handle. Apart from that, this has been a welcome and good value purchase. The pro charged me £180. I have used this hose twice now, it is definitely saving me money.

I used this on a long grill covered drain that runs along the front of my garage.To give an idea of how bad this drain was, it consists of a channel which is around 15cm deep and 10cm wide covered by a metal grate. The channel up to the exit pipe had dirt up to about the 10cm mark and weeds growing in it. Looking into the pipe itself the situation seemed very much the same from what I could see.Water would run off VERY slowly and after a heavy downpour it would take the large puddle which had built up in front of the garage (and inside the garage depending how bad it was) around 20 minutes to clear.Everything in the garage was elevated and during some particularly bad downpours I had actually witnessed around 3cm of water build up in the garage itself. I had called some drain clearing companies and got an initial quote of around £100 with the caveat that if it wasn't a straight forward job it could cost more.Took a chance on this device, at the price figured it would be worth it if it worked and wouldn't break the bank if it didn't.In my specific case, I was only able to feed it into the drain system from the entry side. This meant that anything I was pulling out would wash back in again if I didn't catch it, this immediately made life a little more difficult but obviously not the fault of the product.After clearing the 10cm or so of silt that was lying at the bottom of the channel, I pushed the device in a touch and turned on the washer. It does indeed slither it's way up the drain, but very quickly came to a stop in the build up. I spent an hour or so letting it "run" down the drain and slowly drawing it back, each time getting a bit further, then quickly putting a piece of wood in to close off the drain and let me fish out all the crisp packets, sweet wrappers and other random junk it brought out.Eventually I hit a hard stop, what I can only imagine was some sort of second grate or corner or something it couldn't get round, as it was about 5m beyond the entry point I couldn't really tell, and lo and behold the cleaning pipe was stuck! No amount of tugging or turning on and off would free it up. I stood pondering this for a while and visualising me calling the drain cleaning people who would tell me I had to dig my driveway up to remove the now stuck pipe before I finally had some inspiration. On disconnecting the cleaner from my pressure washer and twisting it round and round while pulling gently, eventually it sprang free from whatever it was caught on. There was a little bit of minor damage to the rubber around the end of the pipe but overall intact and working perfectly.To shorten a subsequently long story, it took several hours of running the device up the drain channel, drawing back, blocking and cleaning, but eventually the entire pipe was clear and water now flows freely away from the drain, and my garage is dry!In summary, I didn't have the easy 5 minute experience of a lot of people here, but I suspect I was the first person ever to attempt to clean out this drain (the last lot just stuck some doors on bricks in the garage for storing stuff on) and it was absolutely packed full of junk, sand (off the mono block driveway) and general dirt. It did the job it was intended to do and I think with a regular once a year re-visit it should be a breeze in future.I can't imagine any blockage situations being much worse than the one I faced so I would definitely recommend giving this a go before you pay the extortionate amounts that the cleaning companies charge.

Quality connections so no leaks. The hose is sturdy so can be fed in and out of blockages without kinking to aid removal. I would have liked the ability to change the nozzle but this one appears to be bonded on, hence 4 stars. But works a treat with my AVA P70 pressure washer and I highly recommend
