Decision to make
Map potable supply, irrigation, boiler, fire protection, commercial equipment, chemicals, hose connections, treatment, and any existing device without dismantling. Avoid using a suspected unsafe connection.
Record to build
MassDEP publishes cross-connection rules, forms, and certified tester or surveyor information and tells applicants to contact the local water authority for certain submittal instructions.
Question to compare
Ask Stoughton and the qualified parties who surveys, selects, approves, permits, installs, tests, reports, repairs, and retests the device. A plumber license and tester certification are separate questions.
Useful closeout
Keep hazard classification or official direction, approval, permit, device make and model, serial, location, installation, test and retest, repairs, tester identity, due date, and owner maintenance file.
