Sooooooo easy to upset the t/m brigade by stating something they don't want to hear, eg, that hoses are heavy and awkward to carry up and down stairs,
I've done the " pull em up and hang em out the windows bit " and the only damage I ever caused in thirty years was to a window frame caused by hose friction.
Just to clarify"..........I would not subscribe to hauling a heavy portable up stairs as there are other options. One would be to use a smaller portable for flats another would be to use a rotary which many are now doing.
Why would anyone argue that twenty five or fifty foot lengths of hose is not awkward and heavy ?
