enters your system, upstream from the pump, serious pump damage can
occur. A tell-tale sign is pump chattering. You can also hear
coming out of the nozzle.
Air can enter the inlet through a loose
connection if your pump is trying to draw more water than the water supply can
produce. Make sure you have an adequate
water supply A loose connection on your fittings or inlet
quick connectors may appear as a leak when the pump is not running but can
turn into an air injector when you pull the trigger. If your inlet
connections are loose and leak, when the pump is running, this
means your inlet supply is greater than the needs of the
pump. This is a good condition but you should still fix the
Air can also enter
pressure soap injectors or high
pressure soap injectors.
pressure injectors, if working properly, will not suck air at
high pressure. They will suck air if the wand has a soap
nozzle on it and the pickup tube is not in a container with liquid
in it. Regardless, this is never a problem
for your pump as the air is being picked up after the pump.
pressure soap injectors however will pick up air, before the pump,
and send it
through your pump and hoses at high pressure. These devices
are located before the pump. If you have a loose connection
or the pickup hose is not submerged air will be sucked into the
pump - this is not good at all.
your pump cavitates,
for an extended period of time you will soon need a new
one! When working a distance away from the machine make sure
someone is checking the soap level.
All inlet air leaks should be attended to right away or
the pump will
cavitate and eventually destroy itself.
