How to Clean Central Vacuum Pipes?

21 Jan How to Clean Central Vacuum Pipes?

A central vacuum system is an excellent convenience in any home. With inlets throughout the house, you must plug in the hose to vacuum all your floors quickly and easily. However, like any vacuum, a central vacuum needs regular maintenance to keep it working its best. Over time, dust and debris can build up in the pipes, reducing suction power and performance. Cleaning the pipes is an integral part of central vacuum maintenance. Cleaning central vacuum pipes can be a DIY project completed in an afternoon with simple tools and supplies. Follow this guide to learn how to get into your main vacuum pipes to remove buildup and keep your system at peak condition.

Why It’s Important to Clean the Vacuum Pipes

Before going over the steps for access and cleaning, let’s look at why pipe maintenance is so crucial for central vacuums. Here are some of the top reasons to clean your main vacuum pipes:

Maintain Strong Suction Power

The suction power of a central vacuum system comes from the motor and fan assembly in the central unit. Over time, dust buildup in the pipes causes added friction and resistance to airflow, reducing suction strength through all the inlets. Clean pipes mean strong suction for optimal cleaning efficiency. Explore how does a central vacuum system work.

Remove Clogs and Blockages

In addition to gradual dust accumulation, larger debris can become lodged in central vacuum pipes. Things like drywall screws, plastic toy pieces, and food spills can obstruct the pipes and hoses. Regular cleaning helps remove blockages and prevent significant clogs.

Improve Air Quality

Like any vacuum, central vacs vent tiny particles into the air upon exhaust. When pipes contain excessive buildup, it can reduce filtration, and more dust kicks back into your home’s air during use. Clean pipes help minimize indoor air pollution.

Extend System Lifespan

Letting debris accumulate can put added strain on the motor and fan assembly. Regular pipe maintenance helps reduce stress on the central vacuum’s components, extending its working life. This saves you money by delaying the need for repairs or replacement.

Prevent Damage from Moisture

Dust buildup can hold residual moisture inside steel pipes, leading to corrosion and rust. Pipe cleaning removes this humid environment, helping prevent costly damage to the system.

Now that you know why it’s important, let’s look at how to clean central vacuum pipes.

Gather Your Materials and Tools

Cleaning the pipes involves some elbow grease and is a fairly labor-intensive process. Make sure you have all the necessary supplies on hand before getting started. Here’s what you’ll need:

• Vacuum hose
• Central vacuum cleaning hose attachment kit with brushes
• Pipe cleaning plumber’s tape with brushes
• Wet/dry shop vacuum
• Work gloves
• Safety goggles
• Phillips screwdriver
• Flat head screwdriver
• Adjustable wrench
• Bucket
• Towels or rags
• Trash bags

Specialized central vacuum cleaning kits provide attachment hoses with revolving brushes to run through the pipes. You can also use plumber’s tape with brushes for snaking out pipes.

For wet cleaning, a wet/dry shop vacuum allows you to vacuum up any damp debris. Have towels on hand for spills and drips. Gloves, goggles, and small hand tools will likely be needed to access various connection points.

Okay, you’ve got your supplies ready. Now it’s time to roll up your sleeves and get cleaning!

Accessing the Central Vacuum Pipes

The first step is gaining entry points into the pipeline system. Here are the main access points found in most central vacuum installations:

Inlets

The wall-mounted vacuum inlets connecting the hose provide direct access to the pipeline. Remove the inlet cover plate, and insert pipe cleaning tools through the inlet opening. This offers convenient access without disassembly.

Outside Access Port

Most central vacuums have an outside access port, usually mounted on the side of the house or garage exterior. This provides an entry point for cleaning hoses without going through the inlets. A cap may cover the port or have a hinged lid.

Electrical Boxes

Look for any electrical boxes along the pipeline route; these will have removable covers and provide access to straight pipe runs. This allows cleaning through long, uninterrupted lengths.

90-Degree Elbows

Any 90-degree corners or elbow joints in the pipeline can be disassembled using a wrench. Once detached, you can directly access the inside of the elbow.

You can thoroughly clean the entire pipeline system by utilizing multiple access points. Now, let’s look at cleaning techniques for both dry and wet methods.

Dry Pipe Cleaning

A dry approach is usually sufficient for routine maintenance cleaning to remove most dust and debris buildup. Here are the dry-cleaning steps:

Start with the Hose

Attach your central vacuum hose and use the specialized brush attachments to clean inside the hose itself. This removes debris before it goes into the pipes.

Snake from Inlet to Inlet

Use your cleaning tape to snake back and forth between inlet openings. Keep going until the sections between inlets are clear.

Access Straight Runs

Use electrical boxes or openings to snake out long straight runs in one pass. Cleaning the entire length of the uninterrupted pipe helps dislodge stuck debris.

Finish at Access Port

Finally, run the hose brush through the exterior access port to clear out the main pipeline leading to the vacuum unit. This gives a complete dry cleaning.

Vacuum Out Debris

Attach a shop vacuum hose to the access port or inlets to vacuum up all the loosened debris and dust. Empty the shop vac frequently to remove all the particulate.

With a thorough dry cleaning, your central vacuum pipes should be cleared of most built-up grime. But a wet method can help remove even more particles for a deeper clean.

Wet Pipe Cleaning

For a periodic deep clean, water can dislodge clingy dust and wash the pipes. Here are wet cleaning techniques:

Disconnect Power

First and foremost, disconnect all electrical power to the central vacuum unit before wet cleaning. Water contact with a live circuit can cause shock or electrocution.

Mix Cleaning Solution

Fill your bucket with warm water and add a small amount of mild detergent. Avoid harsh chemicals that could damage the pipes.

Scrub with a Wet Brush

Dip your hose brush in the cleaning solution and scrub the interior of the pipes. The warm, soapy water helps cut through built-up grease and grime.

Rinse Thoroughly

Once scrubbed, run clean water through the pipes to rinse. Flush until the rinse water runs clear. Check elbow joints and inlets for any remaining suds.

Dry Completely

Remove any puddles of water in elbows or low spots using rags. Run multiple dry brushes through to absorb the remaining moisture. Thoroughly dry pipes prevent corrosion issues.

Vacuum Out Liquid

Use your wet/dry shop vacuum to suck up all the dirty water. Mop up any drips or spills around access points. Proper drying prevents mold and bacteria growth.

With pipes cleaned and dried, reconnect any disassembled joints. Once dry, restore power and enjoy renewed suction power.

Maintenance Schedule

For optimal performance, central vacuum pipes should be cleaned two to three times per year. Follow this maintenance schedule:

• Early Spring: Dry clean pipes after winter use to recirculate indoor air. Helps remove allergens.
• Late Summer: Wet clean for a periodic deep cleaning. Summer air conditioner use adds humidity that can adhere to debris.
• Early Fall: Dry clean again after restoration of closed windows creates dust. Removes particulate before winter recirculation.

Additional cleanings can be performed if you notice a drop in suction performance at inlets.

Signs It’s Time for a Cleaning

Watch for these signs that your central vacuum pipes need some TLC:

• Noticeably decreased suction power
• Vacuum exhaust smells musty
• Pipe access points feel warm to the touch
• Strange noises from the pipes, like flutters or whistles
• Visible dirt streaks around inlet openings
• Hose feels abnormally warm during use

Any of these can indicate excessive buildup in the pipes that need to be cleaned out.

DIY or Call a Pro?

While pipe cleaning can be tackled as a DIY project, you may want to have a professional service come out for deep cleanings. HVAC companies that install and maintain whole-home vacuum systems often provide full-service pipe cleaning.

Consider hiring a pro cleaner for:

• Initial deep clean for a newly installed system
