Domestic Piping

SECTION IV - Domestic Piping

General Piping Requirements

•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.

•Install unions for easy removal of the ELITE from the system piping.

Domestic Supply Pressure

For applications in which the domestic sup- ply pressure exceeds 70 psig it is recom- mended to install a pressure reducing valve on the cold water supply.

Maintaining the cold water supply at or below 70 psig will prevent normal thermal expansion from repeatedly forcing the T&P relief valve open.

Thermal Expansion

If the cold water supply contains a backflow preventer, check valve and / or a pressure reducing valve, the installer must install a domestic thermal expansion tank on the cold water supply. (See Fig. 2 page 14)

Installing a thermal expansion tank will prevent normal thermal expansion from repeatedly forcing the T&P relief valve open.

When installing a thermal expansion tank ensure the charge pressure of the tank is equal to the cold water supply pressure at the point of installation. Consult the ther- mal expansion tank manufacturer’s instruc- tions for further information on installation and sizing.

CAUTION

The Temperature / Pressure relief valve is not intended for constant duty, such as relief of pressure due to normal thermal expansion.

Water Hammer

Water hammer is the effect of sudden pres- sure changes occurring in the domestic pip- ing. These pressure changes are typically the result of “fast acting” positive shut-off valves closing. These types of valves can be typically found on dishwashers and clothes washers.

The effects of water hammering can cause damage to system components and tank welds on the unit.

Installation of hammer arresters is recom- mended at these types of appliances, which incorporate “fast-acting” positive shut-off valves. Consult the manufacturer of water hammer arresters for recommendation on sizing and installation requirements.

Temperature / Pressure Relief Valve

The ELITE has a factory installed Temperature / Pressure Relief valve. Ensure the rating of the T&P relief valve is correctly sized as follows per AGA:

Model
