Hi birdmiller,
I must admit it's not been as good as I thought it would but I am stichking with for my high stuff, I'm not used to leaving so much water around and the whole leaving the windows wet is quite hard to get used to, I'm sure everybody would agree that when you blade a window you can see straight away if there is any problems and you can rectify it there and then.
As a package wfp is very good because you reach parts of the frame that you would'nt off a ladder.
I'm not knocking water fed I think it's me more than anything else i.e I want everything to be perfect straight away and also what works for you, there is lots of people that do it differently, things like some clean all the frame others don't go near the top frame, what sort of jet and brushes.
I've invested about £900 on my system got the 250 liter from pure freedom just to get me going, I have all the kit in the back of my van and 100 meters of microbore.
Hope this is some help.
Gordon.
