Bought a Performer for our detail shop and I had a question about the water pump switch. This is the same switch you hold to the left to bypass low oil to start the engine cold.

The question I have is what does the "on" switch do? I have water pressure whether I have the switch in the on position or not

if you have pressure in both the upright position and "on" position, there is something wrong. You should not have water pressure in the upright position.

You have to turn the black round thing right above the engine exhaust.
On the bottom left of the the machine

And bypass the exhaust from going thru the heatexchenger

Then the pump will turn off. And you can use that switch to turn the pump back on and off

Its for when you just need to use the blower and don't need any water

When you turn the black round knob you will be able to hear a click when the key is turned and the machine is off

That click is the pump clutch
