Q: What is a central vacuum?

A: A central vacuum system consist of a power unit mounted in a garage or storeroom which is connected to a 50.8mm PVC pipe that runs to various points around the house, terminating at a wall inlet. These covered inlets at low level are similar in size to a standard light switch and once these and the unit are installed the system is ready to use. To vacuum, a lightweight, flexible hose is inserted into the wall inlets. All surfaces in the home can be cleaned efficiently using the versatile cleaning tools.

Q: What differentiates Drainvac from other similar maintenance products?

A: Drainvac is a recognized brand across the world and offers the greatest range of products on the market.

Q: What is this Automatic self-flushing central vacuum cleaner?

A: Better known as the Drainvac Automatic, this revolutionary machine—considered to be the best on the market environmentally—connects directly to the water pipes and sewer drainage of a house or business. The principle is simple: water, suction, and a drain. With the automatic-drain vacuum, there are no more bags to change and no more filters to clean—it empties itself.

Q: How does the Drainvac Automatic system work?

A: As soon as the vacuum is turned on, water sprays at the opening where dust enters the appliance. The dust becomes heavier and settles to the bottom of the tank. The tank is sealed by a valve that remains closed when the vacuum is in operation. After 15 minutes, the vacuum stops automatically. As soon as the vacuum stops, the tank empties itself for 10 seconds into the sewer drain of the house or business. Then the vacuum automatically starts again. This cycle repeats itself for as long as the vacuum is in operation. When the vacuum is turned off, the water drains. Water never accumulates in the tank so it remains clean.

Q: Why buy a Drainvac vacuum cleaner in the Automatic series?

A: Most importantly, like all other Drainvac machines, the automatic-drain vacuum can be used to do the weekly household cleaning.
In addition, it can be used to:

  • Empty a spa.
  • Empty a blocked sink, bath, or toilet.
  • Wash the household carpets and couches.
  • Wash the carpets and seats in the car.
  • Wash the windowsills.
  • Wash the cement floor in the garage.
  • Pick up all spilled liquids.
  • And much more…

Q: How do I maintain and clean the Automatic?

A: The only time water travels through the vacuum’s hose and pipes is when picking up liquid. This might leave the hose and pipes dirty. To clean them, simply vacuum some clean water from a sink. Then, leave the vacuum on to suck in air for 10 minutes. This will dry out the hose.

Q: How long should a central vacuum last?

A: Central vacuums typically last forever. Typically, most central vacuums come with a lifetime warranty on the unit. There’s very little, if any, maintenance needed.

Q: What are the benefits of having a central vacuum?

Q: Why is a central vacuum convenient?

A: There is no canister or upright vacuum to lug around or up or down stairs. No dangerous electric cord to get in the way and trip on. No wheels to scratch wooden floors. No damage to walls or furniture. No dust or odors. Better for allergy suffers and better for the environment.

Q: What Inlets would you use?

A: Depending on the application and the power unit model will dictate which inlets are utilized for the installation. Things to consider are styling and color.

Q: Where should I locate my wall inlet valves?

A: The wall valve inlets should be located within six feet of a household receptacle. We suggest that you take a 30 foot length of cord or a measuring tape set to 30 feet then walk though your home and locate your wall inlets so that they cover all the areas you wish to vacuum.

Q: Will a dedicated electrical circuit be required for a central vacuum power unit installation?

A: Yes. It must be either a 15 amp or 20 amp circuit depending on the specific power unit you are installing

Q: My Central Vacuum has lost a lot of its suction. What is the most likely cause?

A: If you have not regularly cleaned your motor filter that may be the cause of poor system performance. Other problems that cause poor system performance are, leaky wall valve inlets, blockages in the intake or exhaust piping, or a blockage in your system hose.
