With a Varistream, and your pressure switch disconnected, it will go to 130 psi at maximum setting, but you shouldn't need it.

It will easily feed a 60ft pole at the end of 100 metres of hose so that will be no problem at all.

Get one with a decent flow rate  5.2 or 6.8 ltrs per minute. Not the 3.8 ltr per minute ine.

Hope this helps

Andrew

1 psi = 2ft

100psi = 200ft

max pressure setting on varistream works out about 135psi = 270ft

plenty.

I've been up 4 storey flat roofs with 150 metre of hose and 63ft up from the ground  with no problems of water flow. (50 metre minibore + 100 metre microbore). Managed a long church with 300 metres of minibore from vanmount before with no problems as well.
