Central Vacuum Pipe

Central vacuum pipe for new installations and repairs: 2-inch central vacuum PVC pipe in lengths from 5 to 500 feet, flexible pipe, clamps, PVC cement, relief valves and swap-out kits. Central vacuum pipe has a 2-inch outside diameter that matches central vacuum fittings and inlet valves, so it is not the same as 2-inch plumbing PVC.

What else you need

• Fittings: sweep elbows, tees and couplings sized for central vacuum pipe. Shop central vacuum fittings.
• Inlet valves and mounting plates: inlet valves or complete installation kits, such as the 3-inlet kit with 48 ft of PVC.
• PVC cement to glue joints, plus 2-inch flexible pipe and clamps for tight spots and the connection to the power unit.
• Low-voltage wire run alongside the pipe, so each inlet can turn the power unit on.
• Replacing a unit? A swap-out kit connects a new unit to your existing pipe.

Want everything in one box? A builder's package includes the power unit, hose, tools, inlets, pipe and fittings. See our central vacuum installation guide.

Frequently asked questions

Can I use regular plumbing PVC for a central vacuum?

No. 2-inch plumbing PVC has a larger outside diameter than central vacuum pipe, so it won't fit central vacuum fittings and inlet valves. Use pipe made for central vacuums.

How much pipe do I need?

Measure the route from each inlet to the power unit, add the runs together, and allow extra for offsets and mistakes. If you're between sizes, choose the next length up.

Why should I use sweep fittings?

Sweep elbows have a gradual curve that lets dirt flow through. Sharp plumbing elbows can catch debris and cause clogs. See how to unclog a central vacuum.

Can I add an inlet to my existing system?

Usually, yes. Tap into the nearest pipe run with a tee fitting, add pipe to the new inlet location, and connect the low-voltage wire. Call us if you'd like help planning it.
