With a 100psi pump behind it, i got a good hard jets from the brushes.
I don't get this one. If you use a Varistream, you disable the pressure switch. If you then turn the control up, you will get a hell of a lot more pressure than the original 60psi.
It's the coiling of the hose that slows down the pressure with micro bore. You try pulling all the hose off the reel and see how much more flow you get.
If you think of a helter skeltor, you would come down a hell of a lot faster if it wasn't for the bends. This affect becomes less as you increase the hose diameter.
Even water is governed by the forces of friction, This friction can build up a back pressure that will be sensed by Varistream, or pressure switch.
I only have 25 metres of micro bore on my trolley reel, but if I turn the Varistream up to boost it will cut off the flow. I could readjust the inner dial of the Varistream. If I do this it causes the connectors to leak. Dai
