may find some misleading claims circulating on the internet regarding
the use of regular schedule 40 plumbing pvc and so-called adaptors.
Claims such as "Thicker is Better", "More Air Flow" and "Commercial
Use" simply aren't true. Some companies will claim that schedule 40
PVC is used in commercial or industrial settings which is very
misleading and untrue. When installing a central vacuum in a
commercial setting, schedule 20 central vacuum PVC is used.
Piping does not vary from residential to commercial installations.
Schedule 20 central vacuum PVC has been used in this industry for over
35 years and is the industry standard. Schedule 40 may in fact be
larger and thicker, but this does not equate to better air flow and/or
better performance. Plumbing PVC fittings are very restricting and
not properly angled, reducing air flow. This is due to shorter elbow
lengths. While this may work well for water flow, it is the very
opposite for air flow. The use of a so-called adaptor only
creates more potential for clogging. You will never find a central
vacuum installer that will use schedule 40 PVC in their installations.
"Always use the
right tools for the job. While some installers
use schedule 40 plumbing tubing and elbows in
place of central vacuum tubing, doing so actually
reduces the efficiency of a central vacuum.
Plumbing tubing has rough inside wall surfaces
and tight elbows that restrict air flow,
encourages clogs and reduces suction."

Plumbing PVC Pipe?
Plumbing PVC is not approved.
probably advise you to rip out your old piping and put in certified
central vacuum PVC.
If your vacuum pipe doesn't have the IAPMO UMC Shield Logo
and/or FlowMax Gold/Excalibur Extrusions Logo in the print line, then is IS NOT
certified to the new ASTM F2158 standard. If you use pipe
that is not certified, a building inspector can fail your
installation and order the pipe to be removed and replaced.
FlowMax Gold and Excalibur Extrusions are the ONLY vacuum pipe in North America that has been
"CERTIFIED" and listed by IAPMO. As explained in February's
issue of Central Vac Professional - this standard is now
being enforced in 19 states effective January 1, 2006.

History of ASTM F2158
Following three years of commitment to the process of the
creating an ASTM standard for central vacuum fittings by the
major participants in the central vacuum industry, we were
pleased to advise you in April 2004, that the American
Society for Testing Materials (ASTM) had introduced F2158 a
"Standard Specification for Residential Central-Vacuum Tube
and Fittings." Revisions to the standard in 2005 are making progress through the ASTM system to include resizing tube
dimensions to more reflect real life and improved testing
methods for fittings, to ensure they will stand up over
time. ASTM F11 group, responsible for central vacuums, are
also writing a new Installation Practices Standard that will
include metal pipe and fittings.
Why was the Standard developed?
The main reason for the F2158 Standard was to promote the
harmonization of central vacuum fitting and tubing sizes so
that an installer could use any ASTM manufactured
product and know it would fit. Another reason for the
Standard was to help ensure that only fittings manufactured
to this Standard would be used in a residential
installation. In this way the industry could present a
consistent dependable quality product to the increasing
demand for central vacuum installations and ensure the
reputation of central vacuums would not suffer because of
inconsistent products. The type of fittings included are
Elbows, Sweep Tee's, 2 Inch Couplings and Wyes. Everything
that is between the back of the mounting plate, to the inlet
of the power unit. It does not include inlet valves,
mounting plates, pipe straps and accessories.
To ensure that any manufactured products remains true to its
design, society has accepted the "marks of compliance" from
designated Third Party Approval organizations. We see this
with electrical products and Underwriter Laboratories (UL)
and Plumbing Products with The National Sanitation
Foundation (NSF). The International Association of Plumbing
and Mechanical Officials (IAPMO) while also being a leading
Plumbing Third Party Approval Agency will also approve and
monitor the quality of manufactured central vacuum tube and
fittings. IAPMO, are also the authors and administrators of
the Uniform Mechanical Code (UMC), the Code that references
the requirements for central vacuum installations.
Choose FlowMax Gold? Here are the key
factors why several Central Vacuum OEM’s have made FlowMax
their only pipe
of choice and why it is the
best vacuum tubing on the market…
High-Quality Material FlowMax Gold is produced only from 100% virgin PVC
material. We use no recycled material or ground-up plastic
of any type in FlowMax Gold. This recycled material
basically comes from discarded plastic products or scrap
that is gathered together, ground up, reheated, and
re-extruded into vacuum pipe. Scrap material typically
varies from lot to lot depending on what has been ground up.
The nature of scrap makes it hard to keep out foreign
materials. Because of this, reused plastic often contains
foreign materials like metal, stone or other non-PVC plastic
materials that can cause poor glue adhesion, holes, tears,
rough inside surfaces, inconsistent wall thicknesses,
out-of-spec diameters, or easily cracked pipes.
FlowMax Gold is
manufactured to rigorous standards to ensure part to part
consistency. Better cuts, consistent fit to fittings, and
superior cement adhesion let you get the installation done
right and quickly the first time – every time. Sorting
pipe at the job site, having to cut out bad sections, or in
the worst case, getting a callback to the job site of a finished home where finished walls must be torn apart to
find a leak, all rob you of your time and profit.
Superior Fit to Fittings
Have you ever had a problem with your fittings being
too loose or falling off the pipe? Have you ever had to
hammer a fitting on to the end of a pipe? If so, you’ve
probably been seeing the effects of bad or inconsistent pipe
Using our proprietary, outside diameter
production control technology, we have remarkable control on
the outside diameter of our FlowMax Gold. This means a
superior and very consistent fit.
