Details:	SUMMARY: Air Entrapment in Waterlines DETAILS: Jim called this morning to report that over the weekend, there had been another air entrapment episode with some loss of pressure in the system. Pressure has been restored and 4 followup distribution systems have been collected and they are awaiting results. Jim is not thinking that the problem is in an old check valve in the distribution system - that is no longer needed - and is getting estimates today from contractors to remove the valve. Jim is hopeful this will solve the problem. ACTION NEEDED: Wait for coliform results and proceed accordingly.
