If I have my pump clutch off is my pump still drawing water from my fresh water tank? I was just on an flood extraction job and discovered my supply hose from my fresh water tank direct to my solution pump was collapsed..........pump clutch was in off position and my gauge showed zero pressure but I’m concerned if the pump was still pulling water it was starving out the pump and my seals may be fried......I’ll change out my hose tomorrow but I’m curious whether or not I damaged the pump.
The technical answer is
No
If your clutch is off (not energized) then your pump is not engaged and therefor not pumping.
But sometimes with time and wear or a misaligned clutch might drag and just slightly engage and cause a light friction enough to draw water but it wont be very strong
I wouldn't worry to much about it unless your system had zero water in it.
if your system has a water box with a float switch then I really would not worry about it since the switch would have shut your engine down
