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 gas-
keted coupler (either ductile iron or PVC). In stal la tion in accor-
dance 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 manufac-
turer’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 hous-
ing 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 struc-
tion has been chosen as Type 304L Stainless Steel. This ma te ri-
al 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 cor-
ro 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.
