We've been testing this for over two years, it has now become a huge part of our kit. We leave every job knowing we will never get called back. It takes literally a few minutes to run it down every downpipe and around the swannecks. You never know if you've cleared any apart from sometimes if they are blocked as in the video it might take a few seconds for it to bite into the blockage, and then it just screws down, we pull it back still turning and gyrating let it go back...job done every time. We remove the actual weed in the downpipe with our downpipe fork (no matter how big) so all that can be left is roots and mud. We have even removed a small sycamore sapling. It made no difference to the downpipe screw.
Our customers love it with all customers fascinated to see it work. It is so basic and obvious nobody doubts it's ability when they see it work and in just a few seconds they know that the pipes are fully cleared.
Our stats on the site show it to be way ahead of any other viewings, and the way the bookings are coming in, demonstrates the importance that they put on the clearance of the downpipes and the importance they put on the no use of ladders!!.
