UFR (Unmeasured-Flow Reducer) – Instructions for Installation.
General – The "UFR - Unmeasured-Flow Reducer" should be installed in line, either in a horizontal or vertical position, before or after the water meter. It is very important that the UFR is installed so that the arrow on the UFR is in the direction of water flow. The UFR - Unmeasured-Flow Reducer, does not require regular maintenance.
Options for installation (by model):
2. UFRs, with threaded male or female connections on either side of the UFR, can be installed directly to the piping.
Installation instructions:
1. Installation of the UFR with a union nut connection directly to the water meter:
A. Close the shut off valves upstream and downstream of the region that the
UFR is to be installed.
B. Match the direction of the arrow on the UFR with the normal direction of
water flow in the piping.
C. Connect the UFR’s male or female threaded connections to the piping, seal
using a sealant that is generally used for potable water systems.
D. Insert the attached seal (fiber, rubber or plastic) into the union nut of the
UFR, connect the union nut to the water meter, and tighten the union nut to the water meter.
E. Open the shut off valves upstream and downstream and check for seal
tightness.

C. Connect the UFR with threaded male or female connections, or to the piping
or shut off valve or water meter coupling. Use sealants that are generally used in potable water systems.
D. Open the shut off valves upstream and downstream and check for seal
tightness.

Prevention of malfunctions in the product during installation:
1. Rinse the pipe that you intend to attach the UFR to, in order to prevent large bodies from entering the UFR.
2. Make sure not to let any sealant enter the UFR, especially the sealing region inside the UFR.
3. Make sure to tighten the UFR using an appropriate wrench on the hexagon flats only.
