Pressure relief valves are recommended for all cold water system installations to protect against damage to

piping and pressure tanks. Valves will be sold at factory pre-set PSI only. Accuracy +/- 15% of factory pre-set

PSI. While field adjustments are not recommended the approximate operating range has been provided by the

manufacturer. Any changes made to the pre-set pressure is entirely at the risk of the person/company who

makes the adjustment. Any changes made should be thoroughly tested for accuracy at the time of installation.

Neither the manufacturer or Boshart Industries will assume liability or responsibility caused as a result of

adjusting the relief valve setting. If the pressure setting is adjusted, it will void any warranty or return of the

product. Relief valves must be installed so that they drain to a floor drain, sump or other safe location with an

air brake. If an outlet pipe is used then it must be at least the same diameter as the relief valve outlet.

For cold water use only. These valves are not T & P valves that are required with water heaters.
