Central Vacuum Cleaner Hose Blocked
QUESTION: The 20' hose for my central vacuum cleaner sucked up a small plastic
garbage bag. We have tried putting several broomsticks in the hose to
push out the obstruction, but it has not worked. Short of buying a
plumber's snake, any other suggestions?
ANSWER: If it's a "plastic" hose:
Try flushing it out with a garden hose, using a wet rag or something to
contain leakage and pressure loss where the two hoses overlap.
If the clog is in the hose, the unit
will build up vacuum, the motor will go
higher pitch and when you try to unplug
the hose from the inlet, there will
be a hugh rush of air. If it is in the
tubing, you won't have the big air rush.
On mine, if the hose is plugged and
plugged pretty solid, it becomes hard
to even remove the hose connector from
the inlet. Also, if the hose is
plugged and you lay it out on the floor,
you can usually see the hose
contract on the wall side of the clog.
Running you ear along the hose
can frequently find a large turbulant
sound at the clog. Sometimes, if you
flex the hose at that spot, it will
break up and get sucked in as the clog is
usually one item catching a bunch of
other things.
