The North Penn Water Authority is advising customers living in Sellersville Borough and West Rockhill Township to boil their water before using it for drinking, cooking or food preparation and to conserve water.
In an advisory posted on its website , the authority said a water main break on a large scale pipe on Sunday morning in Sellersville resulted in a significant loss of water pressure in the entire Sellersville distribution system.
According to the Authority, the water main break was repaired by 8 p.m. Sunday and the distribution system in Sellersville was returned to full water pressure.
The first round of water quality samples were taken at seven locations around the Sellersville area Sunday evening, and must undergo a required incubation period of 24 hours in the lab before results can be read, officials said.
Additional samples will be taken on Monday, and officials said if the readings are acceptable, the earliest the Authority could cancel the boil advisory would be sometime on Tuesday.
The Authority is asking all customers in the affected area to limit usage to the most essential purposes, and to refrain from irrigating lawns and gardens or any other non-essential outdoor use until the advisory is lifted.
