Bundling Zurn PEX Distribution Lines
The distribution lines are run in the most direct route to the endpoint
fixture. If the tubing is not immediately connected to the manifold,
both ends of the tubing should be labeled.
The hot and cold distribution lines can be bundled together if local
codes allow. Bundles should be wrapped with a heavy gauge plastic
sheet at locations where fasteners are attached. This sheet may
be fastened using tape or nylon wire ties. Apply the tape to the
plastic sheet, not the tubing bundle. This will allow the tubing to
slide inside the sheet.
Note:
Tubing run on a continuous support such as a floor in an
attic may be strapped at six-foot intervals; however, when hung
from floor joists or running across rafters, Zurn PEX tube should
be supported or strapped every 32”.
Completing the Installation
Once installation is complete, it is recommended that all ports be
labeled accordingly so that they may be shut off to a particular
fixture. Zurn offers pre-printed label kits for a professional look.
The labels are self-adhesive and can be applied directly to the
manifold.
Zurn also offers decorative access panels that can be used to
cover the manifold. Zurn access panels come with a frame that
can be fastened to the sheetrock with adhesive or screws for
easy installation. The panels snap into place and are flush with
the sheetrock.

Important: DO NOT
hook one tube to support the entire bundle.
Straps should go around the entire bundle.
Installing a Zurn PEX XL or Zurn PEX CR Fitting
Under Concrete
As a matter of good practice, it is best to avoid placing fittings
in an area where concrete would have to be removed if repairs
are necessary. However, there are occasions at which burying a
fitting in or under concrete is unavoidable. When circumstances
warrant the burial of a Zurn PEX fitting in or under concrete, it is
necessary to follow two important guidelines in order to prevent
compromising the integrity of the system.
1. A proper connection must be made. Please refer to pages
7-13 to ensure a proper connection is made based on your
choice of clamp system.
2. The fitting connection must be protected from corrosion
induced by contact with the surrounding soil or concrete.
There are three different methods that Zurn recommends as a
means of pro tect ing buried fittings from corrosion.
Foam Pipe Insulation –
Foam Pipe Insulation can be used as
an effective method of covering the fitting and clamp rings from
corrosion. For proper application please refer to manufacturer
instructions.
Plastic Film –
Several layers of a plastic film such as Saran
Wrap may be used to cover the fitting and clamp rings without
damage to the tubing. While the film generally sticks to itself,
to make sure that the film stays in place during installation,
tape should be wrapped around the film at the body and
the ends of the fitting.
Note: The tape should not come in
contact with Zurn PEX tubing.
Heat Shrink Sleeves –
Heat Shrink sleeves are only used to
protect couplings. The sleeve should be placed on Zurn PEX
tubing and moved away from the crimp area prior to making a
connection. Once the tubing has been connected to the fitting,
the heat sleeve should be centered on the coupling with 3 inches
of sleeve beyond the fitting on either side. Follow the manufac-
turer’s instructions to shrink the sleeve using a hot air gun. When
the shrinking process is complete, the sleeve should be tight on
the Zurn PEX tubing, fitting, and crimp ring or clamp.
Important:
Do not use more heat than is required to shrink the
sleeve. Do not use flames or a torch to shrink the sleeve.
