I think this unit has a utility valve on the front. If so, do you have good suction at this valve? If not, disconnect the inlet piping and check the suction directly from the inlet. Make sure the utility valve is closed while checking the suction on the inlet. If you have good suction, you have an open pipe or valve somewhere in the house. If you have any vacpans, check these first. Next, turn the unit on and walk through the house and listen for air whistling. If you do not have good suction from the inlet at the unit with the utility valve closed, replace your bag and look for a secondary filter that may be plugged. Good Luck!

There's little or no suction on my central vac so I think maybe something is stuck in the piping. how can I troubleshoot and/or fix this?


First, check the hose, wands, and power nozzle. You can check the hose by dropping a coin in one end, then lifting the length of the hose until the coin drops at. If it doesn't, then there's an obstruction in the hose that needs cleared. Depending on where th blockage is, it can be difficult to remove. The best way is to connect the wrong end of the hose directly to the in port of the vacuum and turn on. This presents an opposing suction to the clog and should clear it.
To check the powerhead, drop a coin in the wand end and allow it to drop through. If it gets stuck, there's a clog, probably in or near the elbow. Use a blunt object to gently push it through. You can visually check the wands.
If the filter is dirty, it presents an obstruction to the airflow, and will result in a loss of suction. Rinse and dry thoroughly. I recommend keeping an extra filter on hand and alternate use.
Check all outlets by plugging hose into them and turning machine on. Check for differences in airflow. If there's less suction in one than the other/s, then there's a blockage in that section of pipe, probably at one of the elbow. The obvious place would be the elbow at the outlet. Visually check for clogs.
If all the outlets have a low airflow, my first guess would be the filter in the vacuum, but there could be a clog in the main piping.
Another cause could be leaks in the hose, most likely at the ends where the hose connects to the connector or handle. The hose generally needs replaced if this is the case.
The fan system may be bad, resulting in reduced suction. It will need to be replaced if this is the case.
Depending on the age of the vacuum, the motor could simply be wearing out.
The best diagnosis can be provided by a reputable vacuum repair shop. Take the entire vacuum in for trouble-shooting if none of the above helped.

Loss of suction. we have checked that there is ni blockage.


Disconnect the incoming pipe from the vacuum power unit and turn the switch on (on the side of the unit) while you feel the bottom of the unit with your hand. If BOTH motors come on and sound normal and are producing suction you should feel the bottom of the canister flex or you should feel suction at the inlet connection.
If the bottom flexes but there is no section at the inlet there is an obstruction in the pipes witin the vacuum unit. A stiff wire with a hook bent at the end is usually sufficient for removing the dust stuck in that piping.
You can also unplug the 110v poser then remove the top cover (only 3 or 4 screws) and visually inspect the motors and piping for failures.

Poor suction in system - I have used shop vac to suction all three receptacles. Have checked bag and cleaned everything. Still poor suction. I have one receptacle in garage that works perfectly. Must...


Have you checked the hose for clogs or leaks. Clogged and leaky hoses are an area of concern with any central vac. Unless you hose has a hose sock, then wear and tear from constant rubbing on floors and other surfaces will result in holes and cracks. Pulling the hose can also result in leaks where the hose attaches to the handle and intake connector.
Mix some dish soap with water.
Use shop vac to blow air through hose, with other end capped or "clogged".
Apply soap solution to each end of hose.
If bubbles form, this indicates leakage. Hose will need to be replaced.

If it's just the one outlet, then there's probably a clog in the pipe between that outlet and the main pipe. You may be able to clear it by plugging the hose into a working outlet, placing other end to non-working outlet, and turning vacuum on. This may provide enough suction to **** out the clog.
If not, you'll probably need to use a mini plumber's snake to try to remove it.

A Nutone CV-450 System with inlet nozzle switch issues


You are suffering a connection problem of the hose end fitting to the wall outlet. Either the hose is not aligned with the two pins in the wall outlet, or the pins in the outlet are dirty and not making good connection to the hose end fittting.

Broken Nutone central vacuum unit


most of those systems are plumbed with PVC, but some do use flex throughout the home...
If yours is PVC, visit your nutone dealer and get a new outlet/elbow.
Trim the old elbow off with a drywall saw or other small saw (if you have a sawsall, that is fine) and glue the new one in
if it is flex tubing, it's easier; the elbow threads on. just be sure to hold the tubing so it doesn't drop down,

CENTRAL VACUUM SYSTEM


Disconnect the inlet piping from the unit and check the suction there. Be sure that the utility inlet on the unit is closed. If you have good suction, you have an open/broken pipe somewhere, or possible an inlet valve or vacpan that is not sealing when closed. The easiest way to find it would be to install your tubing back into the inlet of the unit, turn the unit on, and walk around the house listening for air leaks. Good Luck!!

Nutone central vac
no suction on lower level second floor fine
ran fish tape but it does not go all the way through,
do i need to take pipe out.

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Not @ first, try to get a central vacuum cuff and go to each and every inlet / outlet down the basement and put the cuff in the inlet – the central vac should come on and possibly might unclog the pipe, 2nd, try taking another canister type vacuum while the central vac is running and open the inlet door and try to “pull apart the clog in the pipe” – this does work upon occasion if not you can try a plumbers snake – but be careful because the walls of the pvc pipe are thin wall and you don’t want to poke a hole in the pipe or other wise you will have to replace the pipe. The absolute last resort should be to replace the pipe if all other do not work. Feel free to contact your local vacuum dealer in your area or in the yellow pages , or contact the factory @ the phone #’s listed below:
