5、ndard. However, it is offered to provide background information.ASSE standards are developed in the interest of consumer safety. The ASSE Product Standards Committee encourages manufacturers to develop performance requirement standards and testing procedures for their products. These standards have

6、the consensus of manufacturers and others who have pertinent interests in plumbing systems and are acceptable to this organization.For many years, the method of priming traps has been with the use of a water supply trap primer, which is activated by flow in the water supply piping. This method of pr

7、iming utilizes primers that comply with ASSE 1018, Performance Requirements for Trap Seal Primer Valves Potable Water Supplied. This standard addresses alternate methods to ASSE 1018 and addresses trap primers utilizing electric design and drainage-type trap seal primers.Although many of the materia

8、l specifications are detailed within Section 4.1 of this standard, it is the responsibility of the manufacturer and the installer to comply with the relevant jurisdictional requirements.The ASSE 1044 working group, which developed this standard revision, was set up within the framework of the ASSE I

9、nternational Product Standards Committee.Recognition is made of the time volunteered by members of the working group and of the support of manufacturers, who also participated in the meetings for this standard.This standard does not imply ASSE Internationals endorsement of a product that conforms to

10、 these requirements. Compliance with this standard does not imply acceptance by any code body.It is recommended that these trap seal primers be installed, consistent with local codes, by qualified and trained professionals.This standard was promulgated in accordance with procedures developed by the

11、American National Standards Institute (ANSI).This edition of the standard was approved by the ASSE International Product Standards Committee on Nov. 13, 2014 and approved by the Board of Directors on March 4, 2015 as an ASSE standard.

Failure to achieve the minimum rated flo

42、w per Section 3.2.2 through the primer drain tube, per flush, shall result in rejection of the trap seal primer.3.2.2.7 Procedure for Electric Trap Seal PrimerThe trap seal primer shall be installed per the manufacturers instructions. A water supply shall be connected to the inlet and the trap seal

43、primer shall be pressurized to the manufacturers rated working pressure. The cycle “on” time shall be set to the lowest adjustable setting permitted on the device. The trap seal primer shall be activated for a period of five (5) cycles and the discharge from each outlet shall be measured.3.2.2.8 Cri
