Hi William
We've used these kind of hoses in the past and found they don't stand up to the rigours of commercial use. They are primarily designed for gardening. I take it you are going to use it for work. If so I would suggest having a look at some of the ones on offer from companies who supply drain jetting equipment. Plenty web sites
www.powerwashers.co.uk is one.
They are not cheap but will last for years instead of lying bust in the back of your shed.
