Notice the signs
Observe
Read the newest notice and status date directly, confirm that Cohasset Water serves the address, and note the specific household question. A system running average is not a test result from one kitchen faucet.
Note 14
Place the condition before choosing the work

Safety line
Follow any updated town instruction rather than this static summary. Do not create an emergency, stop ordinary use, or recommend equipment from a historic notice when the live authority says otherwise.
Material note
Local boundary
The town page controls current system response and optional filter context. A private plumber can discuss installation mechanics only after the resident identifies a real objective; it cannot certify public water or promise a health outcome.
Service flow
Written scope
For any proposed treatment, request the target compound, independent certification, rated capacity, flow and pressure effect, maintenance cost, replacement schedule, waste stream, bypass, sampling plan, and evidence that the product fits the question.
Close the loop
Verification
Revisit the official tracker before purchase and at installation. Keep model and cartridge records, but do not claim a system has solved the town issue or improved health without appropriate evidence.
