In the picture you see us jetting out a kitchen sink line though a cleanout. Jetting is like pressure washing the inside of your pipe. It uses high pressure water to totally clean out your pipe, doing a much better job then just snaking out your drain.

If your drain has alot of gunk and grease in it, a snake will only open a small hole in that grease where as a jetter will totally clean it all out, so that your calls to a plumber are a lot fewer for clogged drains. A jetter is also a great tool for cleaning out main lines with roots in it. It is capable of totally removing all the roots in a main line. Again, this maintenance keeps you from calling the plumber as often, since it takes time for the roots to block the pipes again

The second picture is a close up of what the jetter’s head does as it cleans the pipe out.
