We have always worked to develop tools that work and are simple. The downpipe clearer is simply a standard pipe clearer that has been use for years, and adapted it for downpipe clearing.
Our mantra is if something is successful simply copy.
That is what we did with the downpipe cleaner.
We let it work until it "bites" then churns through the blockage. We pull it back still spinning and let it turn down three or four times and that is it.
We have cleared hundreds, and never been called back.
We don't charge a lot, but if you are "having it off" financially you can always push a hose pipe up
and round the head to rinse.
It is a relief to leave every job, knowing that you will not be called back.
You should see the faces of customers watching it. The response is always the same, "have you patented that?" unfortunately it is not original to pipe clearing.
