Notice the signs
Observe
Record the backflow model and tag, valve positions, visible leakage, controller program, affected zones, winterization history, recent landscape work, and whether the symptom occurs with irrigation inactive.
Note 18
Place the condition before choosing the work
Protect the room
Safety line
Keep clear of electrical controls and pressurized discharge. Do not bypass a protection device, inject chemicals through an unapproved connection, or use compressed air without the training and safeguards the system requires.
Material note
Local boundary
Use current Cohasset Water rules for registration, approved protection, testing, and conservation requirements that apply. Confirm the authorized roles of the irrigation company, tester, and licensed plumber.
Service flow
Written scope
A seasonal proposal should assign startup inspection, device test, repairs, zone checks, controller settings, leak screening, shutdown, blowout or drainage method, documentation, and any plumbing or permit work.
Close the loop
Verification
After service, retain the test certificate and final controller schedule, inspect the device under ordinary operation, note closed or isolated zones, and place the winter shutdown date where the property manager can find it.
