We purchased a house a year ago it is now 4 years old. We were told it was
roughed in for a central vac. We purchased the central vac and installed it.
The central vac works on in the basement (outlet we installed), and the main
floor. The outlet to the top floor does not have any suction. When we plug
in the hose to the system, it turns on but there is no suction.
Any ideas on what to do?
Thanks in advace.
That is going to be tough. It is either clogged or not connected.
Since it turns on it appears it was intended to be connected.
Can you hear what sounds like the vac when you turn it on coming through
Try fishing a wire or something down the pipe. The sharpest bend should
be right at the outlet. How far can you get?
My guess is you will find a kid's ball or some such thing in it
We had a central vac in our previous home.
When things "went wrong" and a tube got plugged, I sometimes used a hose
from a portable vac to apply sucktion to the non-working outlet.
You can go further (I didn't have to, BTW): if you have an air compressor
you can apply pressure at the central vac end of the tubing and have your
kids (or whoever) hold down the flaps on the working outlet(s) and let the
preesure work on the clog.
Using either technique, I suspect, will likely reveal that the "rough in"
was sloppy and the outlet may not actually be connected in the first place.
The motor part of a central vac system can be had for something on the order
of $100 (cheap unit). I don't understand why someone would install the
tubes but not the central unit. There is something fishy.
Not so fishy. When I had my house built, money was tight and there was
no extra to spare. I had the roughed in vacuum plumbing put in before
the walls were closed in. After a year, I had enough equity in the house
to remortgage and buy the rest of the vacuum system.
