Piping checklist
WARNING:
• The heating of water and other fluids causes volumetric expansion. The associated forces
can cause the failure of system components and the release of high-temperature fluids.
In order to prevent this, install properly sized and located compression tanks and
pressure-relief valves. Failure to follow these instructions can result in serious personal
injury or death, or property damage.
• Avoid serious personal injury and property damage. Make sure that the flange bolts are
adequately torqued.
• Never force piping to make a connection with a pump.
Check Explanation/comment Checked
Check that the suction and discharge pipes are
supported independently by use of pipe hangers near
the pump station.
This eliminates pipe strain on the pump
station.
