ANSI Adopts Water Systems Council/ASSE Pitless Requirements
ANSI Standard Covers Adapters, Pitless Units and Well Caps
The American National Standards Institute (ANSI) has adopted as a standard performance requirements for pitless adapters, pitless units and well caps codeveloped by the Water Systems Council (WSC) and ASSE International.
“WSC and I are pleased to have worked together with ASSE to bring this standard into an ANSI-accredited consensus process,” says John Surinak, president of Maass Midwest Mfg. Inc. and chair of the ASSE 1093/PAS-97 Working Group. “This most recent revision to WSC PAS-97 clarified pitless adapter and pitless unit definitions, revised the pitless adapter and pitless unit testing, and revised the sanitary well cap watertight capability testing. Separate tests for surface water contamination and internal pressure for pitless adapters, and similar tests for pitless units were also developed.”
