G4 mains water

[Andy M]

Set up the G4 to spray a gable on thursday using mains water. Connected up and got a reading of 3 bar pressure which was great and started spraying at around 260 on the flow bottle.
Mid gable and the material starts to get pissy so climbs of the scaff checks the bottle and the reading is now up to 500.
The machine did this a couple of times during the spray so any ideas fellas?

Filters. Check the filters are totally clear. The debris in the filter will swish around and mess with the flow.

Aside from this if the water supply is dodgy there could be another source draining your pressure then releasing it back to you again.

Before you start hook the water up just take the water pipe of the chamber and run it (with the machine head unplugged) for a minute or so. And monitor the float tube reading make sure it runs free and steady. Hook it up to the machine when your happy

Cheers, the filters were clean so I can only assume it was the supply as this hasnt happened before.

Has your G4 got a fitted water pump if so was this switched off or on.
