7 Pcs Sewer Jetter Nozzle, Rotating and Button Nose Stainless Steel Sewer Jetting Drain Jetter Nozzle, Drain Sewer Cleaning Tool for Pressure Washer, Pipe System, 5000PSI,1/4 Quick Connect (A)

Fricken awesome, the little spinner jet saved me about $1,000 from a plumbers fee.Snaked the sewer pipe and got it flowing and then ran these through on the end of a pressure washer hose and it pulled out a pile of pipe wall gunk.

This set provides 4 different configurations of water jets designed to flush out clogged drain pipes ... or quickly open up tunnels beneath hard surfaces or turf covered areas. In my case I haven't yet needed to use these for un-clogging drain pipes, but I have used them on multiple occasions to open up a tunnel beneath a hard surface and insert a water pipe or electrical conduit. The forward facing water jets blast open a path and the backward facing water jets force the loosened material back through the pipe/conduit being inserted through that tunnel. They work great so long as the material being removed is smaller than the remaining space inside the pipe along with your pressure line.One of these heads is designed to rotate and spray water out sideways to clean the entire inner surface of the pipe, not just open a pathway through the pipe (which might otherwise still be nearly clogged). This is a unique feature which I had not previously seen available.A feature not noted in the description is the inclusion of several fine, yet sturdy, "picks" to assist in cleaning out the tiny water jet openings in these heads which tend to become clogged with debris being constantly flushed back at them during the process. These are a very helpful tool and are much smaller than most objects that might otherwise be available to facilitate this cleaning function. A very important bonus feature to this set.

I already had a stiff PW hose, and by added these to my arsenal of accessories, I can now flush out stopped up drain line using PW.
