is it possible to use two water pumps for one system , i have a spair pump and was thinking of fitting it on my system to give more presure at the brush so it blasts out .

it will only be as powerfull as the pump with hiest psi if in line , and volume

you can increase the pressure of one pump by adjusting the screw inside.

this will only alter the cut off pressure though,giving you a blast when you first open the pole tap.

just get smaller jets fitted!!!!!

2mm jets will make rinsing much more efficient withoout wasting all that precious water!!!!
