The Sloan vacuum breaker trap primer provides a constant
water seal in a floor drain. Each time the flushometer is
activated, a small amount of water is diverted to the floor
drain to maintain the water seal. This seal prevents
objectionable sewer gases from escaping into the air.
Sloan VBF-72 and VBF-73 trap primer models are designed
to deliver a minimum discharge of 30 ml per flush when
used in conjunction with Royal or Regal 3.5, 1.6 or 1.28
gpf flushometers. The total amount of water diverted varies
directly with the number of flushes.
Perform the following functions using the rough-in guides illustrated in Figures A and B:
• Install flushometer following the instructions included with the valve. Use these instructions to replace ONLY the
instructions for a Vacuum Breaker Flush Connection.
• Install piping from connection on the floor drain to a desired location on the wall (determined by installer). (Sloan does
not supply the piping for this connection.)
Note: Be sure that approximately 1” (25 mm) of a ½” (13 mm) NPT male pipe protrudes from the wall.

‡Consult local codes for approval of the use of the VBF-72 trap primer with flushometer models 110/111. Some
codes require a minimum distance of 6” (153 mm) between the critical line of the vacuum breaker and the trap
primer outlet. In these cases, specify models 113, 115 or 116.

Insert the smaller end of the black plastic water deflector into the threaded end of the elbow fitting. The flat end of the
elbow fitting will face outward from the vacuum breaker.
Place several drops of thread sealant on the threads of the elbow fitting. Insert the elbow fitting and water deflector into
the threaded hole of the vacuum breaker tube. Screw the fitting into place. DO NOT overtighten this connection. The
final position of the elbow should allow water flow from the vacuum breaker in a downward direction.

Place wall flange over the ½” (13 mm) NPT male pipe used as the trap primer outlet. Push wall flange until it is flush
against the wall. Connect the ½” (13 mm) NPT female tube fitting to the pipe. The fitting will help keep the wall flange
in position.

DO NOT use abrasive or chemical cleaners to clean flushometers, they may dull the luster and attack the finish. Use
ONLY soap and water, and then wipe dry with a clean towel or cloth. When cleaning, protect the exposed flushometer
from any splattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating.

contact Sloan Technical Support at:

Prior to inserting the flex tube into the elbow fitting, ensure that
the restrictor washer has been inserted into the elbow fitting.
The restrictor washer prevents too much water from being
diverted away from the bowl. This helps ensure optimal bowl
performance, even when used with 1.28 gpf (4.8 Lpf) High-
Efficiency Toilets.
Use the 3/8” (9 mm) diameter flex tubing to connect the bottom
of the elbow fitting with the restriction washer to the tube fitting
at the wall flange. Sloan provides a 12” (305 mm) length of flex
tubing. Bend tube to fit installation and cut to appropriate length
(DO NOT CUT END WITH LABEL). Tighten compression fittings
at both ends of the flex tubing. Complete the valve installation
according to the installation instructions included with your
Sloan flushometer.
