Symptom CLOG IN THE HOSE
- Take your central vacuum hose and connect it directly to the dirt canister.
- After turning on the vacuum, if the hose has normal suction then the clog exists in your tubing.
- Then check all the tube for clog.
- But, if you experience reduced suction at the canister then your hose is clogged.
- Plug hose in reverse into the inlet located on your unit and turn on the system. This should aspirate the clog out.
- Or, remove the hose from the inlet and push a garden hose through hose to push out the clog. Most importantly, the garden hose must be turned off and there should be absolutely no water entering your vacuum hose.
- Or, remove the hose from inlet and drop in a heavy object such as a screwdriver to push out clog.

Sypmtom PARTIAL CLOG IN CENTRAL VACUUM PIPE
How to determine a partial clog in tubing
- Turn on unit at the canister and insert a TornadoPower® Cloth through each inlet. If the cloth gets to the canister in one piece you do not have a blockage in that inlet, move on to the next inlet and test again.
- If the cloth gets to the canister but is torn or ripped you probably have a partial clog or blockage.
- Even if you find a clog in one of the inlets, test all the inlets one at a time to make sure you don’t have more than one clog.
- Plug hose into each inlet and place hand over hose end in order to build up air pressure and then release. Try this a couple of times in each inlet.
If you are still unsuccessful in clearing out the partial tubing clog, please call us at 703 997 9292 for solution.
Symptom FULL CLOG IN CENTRAL VACUUM PIPE
How to determine a full clog in tubing
- Turn on unit at the canister and insert a TornadoPower® Cloth through each inlet. If the cloth gets to the canister in one piece you do not have a blockage in that inlet, move on to the next inlet and test again. If the cloth does not make it back to the canister then you have a clog/obstruction in your tubing.
- After you find which inlet run is affected, turn off your central vacuum system and then remove the canister from the system. Then by using a separate vacuum (such as portable wet/dry canister) plug in the hose into the inlet and try to aspirate the clog out. This method works most of the time.
- If the above did not work, you can try using a plumber’s snake through the inlet to push the clog out.

UNIT RUNS CONTINUOUSLY (won’t shut off)
Follow these steps to determine the cause of this central vacuum issue
- If your unit has an on/off switch make sure that it is in the off position. Disconnect one of the low voltage wires from the unit body.
- If the unit continues to run, you have a bad relay and it must be replaced.
- Call us at 703 997 9292 to determine which relay you need
- If the unit turns off but turns on again when you reconnect the wire, you have a short in the system wire.
Investigating a short in the system wire
- The short may be occurring in one of the inlets. While the unit is running, check each inlet by un-screwing the faceplate from the mounting bracket. If the unit stops after backing out the screws that secure the low voltage wires then remove that valve, reverse the wire, and carefully screw the faceplate back to the mounting bracket.
- If you’ve checked all inlets and this does not solve the issue, check the wire in any accessible space where the pipe and wire may be reached such as a crawl space, attic or basement. You may find that if you had any recent service work done on your house that it may have caused the short.
- Another possible cause may be rodents chewing through the wire and causing the short. If you locate this, repair wire.
- If are still unable to fix this issue, you can purchase an RFX Remote Controller. This product will allow you to turn your system on and off with a key fob type device from any part of your home.

CLEANING YOUR CENTRAL VACUUM PIPE
TORNADOPOWER® Central Vacuum Maintenance Cloths are the do-it-yourself solution for central vacuum system care. These handy cloths are the ultimate way to reduce odors and restore your system to peak efficiency.
Turn on unit at the canister and insert a TornadoPower® cloth through each inlet and through your hose. The textured cloths are specially formulated to capture dirt and grime residue that exists in the hose and tubing. Also, when pulled through the pipe system, these cloths capture larger debris such as pebbles, lint, sticks, etc. and deliver these items to the canister. Finally, the treated cloths “wipe down” the inside walls of hoses and tubing, and their scented solution leaves the entire system smelling clean and fresh.
