I used to hate using the drain rods, right pain in the arse.
You are doing it wrong!

The guy I got it off said to be careful as it could easily strip you to the bone if you're not careful, obviously I haven't tried that but I believe it could.
Like compressed air, High pressure water is potentially very dangerous. You also need to wear face protection. Not so much because of the water as such. Just that you donrt really want to get somebodies Richard hitting you in the eye!
