Description
This standard covers trap primers used in conjunction with fill valves and flushometer valves, electrical trap primers and trap primer adapters, and specifies requirements for materials, physical characteristics, performance testing, and markings.
The trap seal primers are of 4 types:
a) Those that are installed on waste line tail pieces from fixtures, such as lavatories, sinks and similar fixtures where grease is not normally generated;
b) Those that are used in conjunction with fill valve (ballcock) assemblies;
c) Those that receive flow from flushometer valves; and
d) Those electric trap seal primers that discharge water automatically and are upstream of the air gap or vacuum breaker.
Working Pressure
Pressurized trap seal primers covered by this standard are designed for a working water pressure range of 25 to 125 psi (172 to 862 kPa).
Connections
Tapered pipe threads shall comply with ASME B1.20.1.
Dry seal pipe threads shall comply with ASME B1.20.3.
Compression assemblies shall comply with SAE J 512.
Solder connection fittings shall comply with ASME B16.18, ASME B16.22, ASME B16.23 or ASME B16.29.
