15 or 20 Amp Circuit

Robb - Minneapolis: Am I able to wire this unit into a 20 amp circuit, or does it need to be 15? Thank you!

You can wire into either 15 or 20 amp. It only pulls 2 amps. Thanks for asking.

Aerus Compatible?

I have an Aerus CentraLux, will this cover work for my system?

Yes, your system used an electrical inlet with two small holes above the main hole. So this would be the part you need.

Almond Lighter Than Ivory

I am looking for a supervalve in a color to match off white switch plates. White is too white. Of the almond and ivory colors, which is lighter in color? Thank you. Georgia Smith Freeport, IL

Beam System, Nutone Inlets

I am installing a Beam Central Vac System. will the nutone electric inlets work with my vacuum system and the 2"OD pipe for nutone work?

Nutone is selling the same electric inlets we all sell. They are the same and work with Beam, standard 2" OD pipe and connectors, and the items we sell here such as the highly rated Stealth Kit (

Blackened Prongs on Direct Connect Hose

the male prongs on my direct connect hose smell and look burnt, how did this happen and what is the solution?

The prongs that go into the wall valve are blackened from a short. The short is at one of the valves, at least. Look for blackening and replace that valve and clean up the cord prongs. Also, be sure to turn the hose off before unplugging as this will cause a short in all your valves.

Brown Available?

Do you carry the Hayden Square door supervalve in Dark Brown ? Thanks

There was a brown one but they discontinued it. You can buy a different color and spray paint it.

Change Out to Electric Inlets?

How can I switch my valves from the basic to electric-is it an involved process? Do I need an electrician? Thanks.

It is possible under the right circumstances. If your backing plate has gaps in it between the main hole and the screw hole then you or your electricia can run one of our ElectraValve Rough-in kits and use the ElectraValve cover plate. The romex with molded end provids the two prongs for an electric hose to plug into. The other end of the Romex can be ran to a J-box in the same stud bay or out of the stud bay (top or bottom) and tied into electricity. It is only pulls 2 amps for the power brush. For more direction please call us.

CL-395RK Inlet Compatible?

Hello. I have nutone #cl-395rk rough in kits. Can I use your #662-HBR inlets to trim out? Thanks!

The CL-395RK is the ElectraValve product, not SuperValve and they are not compatible. So to finish your installation you need the ElectraValve inlet covers toward the very end of this page

Convert Basic Inlets to Electric?

i need to change from a non supervalve ( no electric for beater brush ) to a supervalve (with electric for beater brush ) help

It all depends on the backing plate in your wall. If you have openings above and below the main suction hole then you might be able to. You'd use the yellow ElectraValve romex with molded end and a new ElectraValve cover plate found down on the page here

Deep Wall Connection

I need to install a SuperValve for my garage through a 2"x10" and double layer of 1/2" sheetrock. How is that done? Is there some type of extension piece I need to make up the extra thickness?

Yes, you can put as many Inlet Valve Extensions as you need. Use long romex and low voltage wires and extremely long screws (which may be a problem if you can't find them). is the extension.

Door with Whip Only?

Was wondering if you sell just the supervalve trim inlet in white, without the rough-in. Would this include the 6 in. elec. whip? The house caught fire and I am just looking to replace the inlets with new white ones. Thanks, Mario in Detroit

The kit has both the door with attached wire and the backing plate. We don't have them separately because they cost the same from our vendor, believe it or not.

Easier to Install in Existing Homes?

My name is Bruce. I am looking into purchasing a C.V.S. for my 5 year old home in Windham Maine.I would like to know if there are any old work inlet boxes on the market to make it easier to install after the sheetrock is up.

Actually, the Electravalve rough-in kit and faceplate are easier to use in existing homes like yours. Find them under Electric Inlets.

ElectraValve Replacements?

Hi, Jack in Hot Springs Village, AR. I need to replace several Inlets for my M&S central vac system. The hose is a Conductaflex 208CE and it carries 120 volts for the power brush as well as switch power for the 24VDC control system. Which white electrified Inlet should I order to replace my ElectraValve units which, unfortunately, carry no part number? Thanks, Jack

Below the SuperValves are the ElectraValves, including the replacement covers. Please see them here You will want the white door #663CW. The plug and the low volt wire attach to it.

Electrolux 46599 and 46800 Replacement

I want to replace an Electrolux inlet because of a broken door. The label on the hose says to use #46599 or 46800 only. Which of your inlets will replace it? Please advise.

Any of the SuperValves are the correct replacements for Electrolux inlet valves 46599 and 46800. It is a direct replacement. Thank you for asking.

Electrolux Compatible?

Is this compatible with an electrolux central vac system?Mine is low voltage to turn on unit and 120 to operate beater brush. Thanks, Bill Stamford,Ct.

The SuperValve has the low voltage contacts within the large opening and then two small female contacts for the 120 volts. If you have that now then this is the correct replacement, they are industry standard and used by all brands. If yours says VacuValve anywhere on it then you have the less often, but similar valve, that is replaced with the ElectraValves and corresponding faceplate.

Extra Hose Length Needed

I have an M & S AV425 central vacuum. I have had it for 11 years and I am pleased with it except that the hose is too short. What I would like to do is add a separate 15' section of power hose, that I would plug into my existing inlet and then plug my existing power hose in the other end of my new power hose. My existing inlet look like your SuperValve Inlet Cover Kit Square Door. Although my existing inlet powers the suction and the beater bar, the beater bar is not required for this as our carpet is all within reach with our existing hose. Please advise.

Since you don't need the electrical to work with it, all you need is a Basic Hose ( It will fit your wall inlet and the attachment end, the metal pipe end, will go directly into the hole of the wall end of your electric hose. If you needed to also extend the 110 volts you would need a new 25' Electric Hose and a couple #480AC adaptors (this will only work if your original hose is direct connect, not corded).

Filtex TS-300L Replacement Inlets

I am trying to replace the wall inlet valves on my Filtex TS-300L model central vacuum. I'm not sure which model is compatible with it and whether I need low or high voltage. Any guidance would be greatly appreciated. Roush, San Diego

If you have the original Filtex inlets, that say "Filtex" on the door and start the vacuum when you open, then you can replace the inlets. However, the hose that fits these inlets is too large for standard inlets. The hose would need to be replaced as well. Low voltage inlets will activate the vacuum; electric inlets will have 120V inside them to power an electric carpet brush. You can view your options here with instructions on replacing the Filtex inlets,

Finishing Black and White Wire Rough-in

Tom - Phoenix I am trying to finish off a pre-plumb and when it was roughed they pulled they high volt (black - white) out through the inlet hole of the trim plate and wire nutted the ends. Is there a high volt slip in receptacle with screw or terminals available? We could pull the plug out of one of your Supervalves but then we would be making it up with wire nuts out of a box in the wall. Thanks!

Any of the SuperValves we sell will be required to finish the job. Wire nut the wires on the on the faceplate to the ones sticking out, tuck them in the cavity in the backing plate and you are good to go. As you noticed the backing plate is always included with the faceplate when buying. The faceplate is the expesive part therefore the backing plate is always included.

Four Wires at Inlet

Hello, I'm trying to attach a central vacuum hose inlet but I have one wire coming out of the hose in the wall. That wire has 4 colored wires inside. How do I connect that to the inlet, which has two contacts? Thanks.

You will have to remove another inlet to see the wires or pattern they used. Or go to the collection unit and see the same thing there. Follow the same pattern.

Grounding, Daisy-Chaining

Hi - How do you GROUND the 110v electric wire to the supervalve? I have a romex# 12/2 electric with a black, white and cooper ground wire that comes from the juntion box? Also, can I run 110v electric from supervalve to supervalve instead of running a separate electrical line from the junction box for each supervalve? There isn't too much room for electric in the small plastic area of the supervalve. Thank you!

UL doesn't require grounding for the valves. Tuck away the ground wire, there is not a ground wire on the wires attached to this inlet. For the wiring we strongly suggest a short run into any nearby junction. The intention is for one wire to entire the attached box for connections.

Hoover Central Vacuum Inlet?

Does your inlet cover work on Hoover model S5673. This model has an electric brush with a cord to plug into an outlet. My name is Vernon and I live in Sebastopol, Ca.

Hi, this valve can work for some but you actually have Basic Inlets since your hose is pigtail corded. See the inlets here for your replacement choices

How Does it Work?

Hi, I'm John from Canada. I had an old system with an old inlet with four screws holding it in. My new system is the universal inlet with only two screws. I cannot see how the new inlet will work. Can you help me?

All inlets have a control wire attached to the back of them. The wire goes back to the main vacuum unit where it is given some voltage. When the two leads of this wire touch each other the suction starts. They usually touch each other when a hose is inserted into the inlet. There are two small metal pin points inside. Some hoses have an on/off switch on the hose that activates them (the hose has control wire running up to the switch). The SUPERVALVE in question here also has an 110 volt connection above or below the main suction hole, depending on how it is mounted. The 110 volts gives power to an electrified hose and carpet brush. Inlets without the 110 volt connection can still accept an electric hose and brush because the compatible hose will have a pigtail cord that is plugged into a regular electrical socket nearby.

How it Fits to Pipe and in Existing Home

how do I connect 2" pipe to 2" tube on backing plate ? The standard connector has a larger diameter ie it fits over outside of pipe and backing plate tube . What confuses me is backing plate seems to be designed so that connector goes INSIDE its tube . Second query is how do I instal backing plate behind existing wall lining ? There are provision for screws but these should be behind plaster or wood lining . Thanks Wayne Melbourne Australia

The faceplace has a neck that fits into the backing plate. The backing plate has a ring in the back of it that fits a 2 inch outer diameter central vacuum pipe into it. Hope that answers that. For existing walls you take the flange with three holes in it completely off the backing plate. There is a raised rim in the front of the plate that you cut to size in the wall. There are flanged at the top and bottom that will pin the wall between them and the faceplate when it is screwed on to the backing plate.

How To Replace 1750 Inlet Valves

I have a Beam cvs with 1750 inlet valves. One has a broken door spring that must be replaced. You have multiple answers that confirm that the entire valve unit must be purchased, not just the door. My question is - can the door be replaced without disassembling the entire unit. I'd be happy to purchase the whole thing, but messing with the dual electrical feeds is more intimidating than just replacing the door. Does the door "pop off" once the two mounting screws are removed?

The door does not "pop off"; you will need to disconnect and reconnect both the high and low voltage wires. You can view a "How-To" video on replacing these valves by clicking here:

Includes Cover Plate with Leads

Does the Hayden 662HA kit include everything needed to install an inlet, including the high voltage pigtail and the cover plate? Thanks, John ...

Yes the cover plate is included and it has the pigtail with short leads off the back side of the cover plate.
