I dont know how I ever coped using the 40  and 60 psi pumps.
I have just bought a 100 psi shurflo pump from williamsons and its totally made the system complete.
It rinses much quicker, the jets now work like they should, in fact its just brilliant.
You would never believe how pleased I am.
Thanks guys for putting me in the right direction.

If I turn the Varistream up it will shoot jets of water 20ft or more from a 60 psi pump.
I read somewhere that the Shurflow pumps are basically the same, and it was the pressure switches that determine the cut off point. If this is the case, what happens when we disconnect the pressure switch to fit a Varistream? Does a 60psi pump become the same as a 100 psi one? Does anyone know for sure? Dai
