Central Vac

[Newbie]

I have a partial blockage in my central vac system. How best to locate the blockage?

Tie a string to your gerbil (like you usually do) and let out the line until he stops. Pull him back out (like you usually do) and then the length of the string will tell you where it is....

Use a plumber's snake. ...thehick

The most common place is right at the outlet. If it was properly installed the smallest opening and sharpest turn in the whole system will be at the outlet.

First find out what outlet(s) have low suction. That should direct you to where you need to look. As noted a light weight plumbers snake can be used, but be sure you don't poke it into the motor unit. :-)

I suspect you will find the problem at one of the outlets and if you look carefully you may see some sort of string snagged there and the clog will be on the other end of that string.
