6、tions or flow in the water supply piping. Thismethod of priming continues to be the method of choice by some members in the plumbingcommunity, although priming devices, which are addressed by ASSE 1044, provide trap sealprotection by utilizing electronic design or drainage-type trap priming devices.
7、The critical feature in these devices is the backflow preventer. This standard addresses criteriafor the evaluation of the backflow prevention features.Recognition is made of the time volunteered by members of the working group and of thesupport of the manufacturers who also participated in the meet
8、ings for this standard.This standard does not imply ASSEs endorsement of a product which conforms to theserequirements.Compliance with this standard does not imply acceptance by any code body.It is recommended that these devices be installed consistent with local codes by qualified andtrained profes
9、sionals.This standard was promulgated in accordance with procedures developed by the AmericanNational Standards Institute (ANSI).ForewordTrap Seal Primer Valves - Potable Water SuppliedASSE #1018 Revised: 2001Trap Seal Primer Valves - Potable Water SuppliedASSE #1018 Revised: 2001Richard J.
