im thinking of buying a booster pump for my 4040ro and i was just wondering is it just a case of connecting it to my outside tape and turning on or do i have to have it coming off a water butt or something

Connect it straight from your outside tap/mains, straight into your RO system.  Make sure your tap has a proper non return valve on first though.

PJ- Could you please help me?
I am going into drive cleaning.
I have bought all the gear -(van,4000 psi powerwasher, flat deck cleaner,1000 ltre tank)
Can you tell me do I have to put a submersible pump in the 1000 ltre tank to boost the pressure enough to run the powerwasher.
It can run at 13 ltres per minute.
Your help would be much appreciated.
