Additional
ProVent® Innovations
In addition, ProVent has produced innovations which improve the
contractor's profitability and competitiveness and provide a
superior job for the clients of the architect, engineer and
contractor.
The ProVent® Double Wye
Fitting
The ProVent® Double-Wye fitting has two openings that are offset to
ensure that branch piping enters the horizontal pipe above its
centerline. The way in which the Double-Wye fitting can be used with
the ProVent® StackVent is shown in the piping layout for the Back-to
Back Bathroom schematic, below.
22o PVC
Elbow
When used with the 22o-angle side openings on the Double-Wye,
the 22o PVC Elbow allows the branch piping to be "rolled"
to the correct angle for the various openings (as shown in the
piping layout, below).
Whisper Quiet Shell
Pipe
This innovation allows a PVC Plastic DWV system to function more
quietly than a cast iron system! To learn more about Whisper Quiet
Shell Pipe and to see a video on the sound-testing results and

Fixed Point
Fabrication
Almost all high-rise bathroom layouts are repetitive from floor to
floor. In the example shown below, you can see how the combination
of ProVent's innovative products leads to a simple and elegant
layout which allows one StackVent to pick up all the fixtures in
back-to-back bathrooms. This allows the contractor to gain the
productivity and quality control benefits of fixed point
prefabrication. To learn more about fixed point fabrication with

All plumbing
contractors need to take a closer look
at this new single
stack DWV system
It
functions beautifully,
costs less money,
secures the piping
and the PVC
doesn't corrode or deteriorate.
It can help the contractor
improve profitability and
competitiveness.
That's valuable at any time, but
in today's slower market, it's
critical!
Back-to-Back Bathroom Example
A typical hotel bathroom (see below) usually has fixtures on both
sides of the Stack Fitting as shown. The ProVent Double-Wye
fits between the stack in a 6" wall and a 12" rough water closet.
The two 2" side openings are molded on a 22° raised angle so adding
the 22o PVC Elbow allows you to roll the branch piping directly to the
various openings.

Picking up the
lavatory underneath the slab eliminates the need to drill through
all the stud walls. The top rough can be completed without any
walls. The sleeves support the pipes without using regular
hangers. The bath tub waste connects to ProSet’s tub box.
The ProVent
System™ is particularly effective in these types of multi-story
(hotels, condos and apartments) where it creates considerable cost
savings as well as enhanced performance and longevity. It
increases the capacity of the plumbing stack, eliminates separate
vent piping and minimizes pipe penetrations.
The ProVent Stack
and the ProVent Base Fittings reduce the maximum flow velocity,
increase the stack waste water capacity and control the interior air
pressures that can cause siphonage and blowouts of fixture traps.
NOTE:
The plumbing
approvals for using this system are granted under the Alternate
Materials & Methods or the Alternate Professional Engineers Design
criteria in the Plumbing Codes. The controlled flow methods
used with this system can make it superior to conventional DWV.
