Leaving Hose Plugged In

Does it matter if I leave the suction hose plugged in when not in use? Jan

Answer:
Hello Jan, you can leave the hose plugged into the wall port, but if the pressure where your unit is becomes greater than in your home then air will flow from the dirty vacuum into your home via the hose. That's not a good thought.

Powerful Suction Now Weaker

As a handyman, I have a client with the Silent Master central vacuum, installed 6 yrs. ago. They are not happy with the suction, and would like to upgrade to a more powerful unit. Can you suggest a replacement? Thanks! Neal

Answer:

We usually find that there is another issue when someone states that about their central vacuum. For instance, on two motors systems, one motor may be out. Or they are developing a clog. Try using the troubleshooting chart. Go through all the steps so you do a complete test of everything.

Install into Existing Homes?

We've had a Silent Master for 10 years and just love it. We are getting ready to move to a smaller home and it doesn't have a central vac. Can a Silent Master be added to an existing home? I don't think I could go back to a regular vacuum cleaner again. Patti

Answer:
Yes, the SilentMaster can be added to an existing home without opening up any walls. Pipes are ran into the wall from below or above and then to the garage or basement where the Silent Master is located.
