Seems like a brilliant idea to me!

Arthur 51 presented the following explanation :

The idea has been around for many years, Karcher just started selling an adaptor for their pressure washer. Look up Jet drain clearing.

It works on the same principle as the 'jetters' used by the water companies for unblocking sewers.

It probably works ok on small blockages, but is unlikely to make much impression on anything serious. I have a main sewer running through my garden and - on several occasions when that has blocked - Severn Trent have sent one of their jetter lorries - with a long fat pressure hose and a pump driven by a powerful diesel engine - and even that has struggled to unblock it!

I thought the conventional water jet services use a hose with a forward facing jet. Do they use the same action as the karcher kit?

I bought an 8m one when screwfix had them on clearance, I attached it to a cheap pressure washer but haven't used it in anger, it unblocked a couple of leaf blocked drains. Main thing is to poke it in the hole before you switch it on!

I expected it to have the main jets pointing backwards but a small jet forward to cut but mine only has two rear facing holes. I imaging this could easily be machined up from a pies of brass with a 1/4" male BSP thread on it to attach to a standard hydraulic hose.

The ones I've seen have *both* and I'm pretty sure they can control them separately - so there must be two internal cores in the pressure hose. The backward jets propel the nozzle along the pipe. and the foward ones cut into the blockage when they get to it.

Same action, but entirely different performance. Cheap DIY pressure washer

100bar x 6 ltrs/min, drain jetter 200 bax 30 ltrs/min.

Drain cleaning nozzles have 3 backward jets and one forward, no internal cores in the hose, no control at all

Correct, but there is no control.

Dead right. Even a small jetter would have at least 10 times the power of a DIY pressure washer, 20 or even 30 times the power isn't uncommon.

I tried using a large waterblaster to clear a drain that was probably blocked by silt. It had no effect. I cleared the drain by making a flat rubber plug that blocked the drain and attached a hose fitting to it. I connected a hose and after a few minutes the drain was clear.

I bought one to clear a blocked drain - it worked pretty well. Used with a mid-higher range Karcher domestic pressure washer

The blockage was due to years worth of fat from the previous occupants which seem to have mostly blocked the drain and then caught lots of other crap.

It did a pretty good job of clearing it - lots of large fatty lumps came out. Though about 6 months later it got blocked again - was still some fatty crud catching stuff left. but another go and it has been fine since (a couple of years?)

I also used it when another boit of the drain got blocked - in this case it was loads of roots that had grown down a diused bit of the drain into the main drain for the house and then gradually blocked the drain.

Nope I wouldn't use it for unblocking a main sewer, but for a typical domestic drain, with a typical type of blockage I think it works pretty well. it isn't as good as a proper jetter I'm sure, but it saves the cost of hiring or paying for someone to do, and having the tool here means I can clear a blockage straight away.

I'm happy with the purchase.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Arthur 51" saying something like:

Seems like an overpriced kit to me! I'd also need an adapter at £38, so no thanks.

I bought a B&Q branded one in one of their clearance sales, only £8 but no more than 10 m long (no i am not going to measure it, its too cold). It came with adapters for several fittings including the Karcher bayonet and more importantly a screw fitting to fit my 15 m extension hose so it will get farther up the drain. I have never had to use it BTW.

Just for the sake of completeness, the backward jets are also used to flush & clean the pipe as the hose is pulled out with a side to side twist - just remember to turn off before it finally emerges :-)

Well yes, if I found one for that price I'd have it. Now seriously thinking of a simple jetting nozzle and knock up an adapter for my existing hose, which is ~10m long.
