Thermal expansion

Water hammer

If a backflow preventer, check valve, or pressure reducing valve is piped on cold water inlet of water heater, you must install an expansion tank on cold water supply line to prevent normal thermal expansion from repeat- edly forcing open T&P relief valve. The T&P relief valve is not intended for constant duty, such as relief of pressure due to repeated normal system expansion.

Refer to expansion tank manufacturer’s instructions for proper sizing.

Failure to follow the above could result in severe personal injury, death or substantial property damage.

Dishwashers, clothes washers, and fast-closing positive shutoff valves incorporated in the system all contribute to creating water shock. Install a water hammer arrester to prevent damage to pipes and appliances. See control manufacturer’s instructions for application and installation.

General piping information

•For domestic water piping, see pages 8 through 12.

•See pages 22–23, for domestic water recirculation piping.

•See Table 1 for piping connections:

•All plumbing must meet or exceed all local, state and national plumbing codes.

•Use pipe dope or tape suitable for potable water.

•Use isolation valves to isolate system components.

•See Section B for Gas boiler and system piping or Sections C boiler and system piping with other boilers.

If domestic water-side pressure exceeds 70 psig, install a pressure reducing valve to prevent pressure spikes. Higher pressures can cause the heater pressure/temperature valve to lift or weep.
