Transition Riser
Sizes: 4"- 10" (100 – 250mm)
Basic Installation Instructions
Watts Regulator Company Transition Risers are designed for
easy in stal la tion in stan dard con fig u ra tions as outlined using
stan dard con struc tion meth od.
The floor penetration detail of the transition riser shall be
re strained per direction outlined by site plans. Consult Uni-Bell
hand book of PVC pipe if instructions are not pro vid ed.
The below ground connection is a standard AWWA C900 gasketed coupler (either ductile iron or PVC). In stal la tion in accordance with the following information (from Uni-Bell handbook).
1. Clean out inside of coupler making certain the beveled spigot
end and the gasket groove are free of dirt.
2. Apply lubricant to beveled spigot (male).
3. Insert gasket into coupling groove and seat firmly.
4. Push lubricated end past gasket into the bell housing. (Watts
Transition Risers are equipped with the lugs placed 180°
apart on either side of the unit which can be used to “pull”
the pipe into the bell using a “come-a-long” type equipment.
Also, the “bar and block” method described in the Uni-Bell
handbook can also be used for installation).
5. The maximum allowable pipe deflection angle between the
TR and underground pipe is as follows:

The above ground connection is an AWWA specification C606
groove. All underwriters Laboratory approved groove couplers
made to fit the AWWA C606 grooves can be used to join the
connection to the transition supply line.
1. Check gasket and lubricate it using groove coupler manufacturer’s recommended lubricant or approved equal.
2. Install gasket. Place gasket over pipe end being sure gasket
lip does not overhang pipe end.
3. Align and bring two pipe ends to geth er and slide gasket into
po si tion cen tered be tween grooves or each pipe (no por tion
of the gas ket should ex tend into the groove of ei ther pipe.)
4. Apply housings. Place housings over gasket, being sure the
housing keys engage into the grooves of the pipe. Insert
bolts and apply nuts finger tight.
5. Tighten nuts: Tighten nuts alternately and equally un til housing bolt pads are firmly together metal to metal: Uneven
tightening will cause gasket to pinch.
Materials
Because the Transition Riser is buried, the material of con struction has been chosen as Type 304L Stainless Steel. This ma te rial is gen er al ly recognized as a corrosion resistant ma te ri al which
is superior to Cast, Ductile Iron, or Coated Steel pipe for corro sion resistance, and which is superior to en gi neered plas tics
for strength and longevity. In general, the stain less steel is the
cath ode in joints of dis sim i lar metal, so that any corrosion which
may occur will not affect the stainless steel. In addition, an extra
pro tec tion is provided in that there is no ac tu al metal to metal
con tact at either joint due to the CIPS bell con nec tion de sign
and the groove coupler design.
IMPORTANT: Inquire with governing authorities for local installation requirements.
ATTN. INSTALLER: “After Installation, please leave this instruction
sheet for occupant's information.”
Installation Practices
Good installation practice for all types of buried pipe of ten calls
for wrapping of the pipe to decrease corrosion due to soil conductivity. Although stainless steel is less sus cep ti ble to corrosion, local codes and general practices should still be followed.
Field Test Procedures
Normal field test procedures call for a hydrostatic pres sure
test of the system prior to final acceptance. Often, seg ments
of the system will be tested individually prior to the complete
system test. In order to hydrostatically test the transition riser as
installed, two methods are rec om mend ed.
1. Constrained Piping
If the piping installation is essentially complete, the pip ing
restraints may adequately take the thrust loads gen er at ed by
having a blind end on the pipe system. In these cases, no
special actions to restrain thrust or side loads are required,
and the fitting installed in the system may be ad e quate for
hydrostatic testing.
2. Free Piping
If just the riser or riser/main connection is to be tested, then
the thrust loads from the blind end cap on the riser may need
to be restrained. The riser design has been test ed in the
unrestrained state using a rigid coupler and end cap grooved
fitting. Flange adapters, expansion fit tings, or other styles
of end connectors may result in ex ces sive end thrust which
may cause a leak or fitting mal func tion. In addition, couplings
which are adequately rat ed for high pressure testing should
be used if thrust re straints are not feasible.
NOTE: It is important that all air is bled from the system
be fore pres sur iz ing any component.
