The same symptom may come from a fixture, an interior branch, a buried private line or shared plumbing. These details help prepare the right response.
After heavy rain, note where the water appears: floor drain, plumbing fixture, sump pit or foundation wall. A backwater valve must remain accessible and a sump pump must be testable; their presence does not replace finding the cause.
View backwater valve service →If several units are affected, mention it during the first call and confirm access or water-shutoff rules with the condo association or building manager.
Residential plumbing →The route, depth, underground services and the boundary between private and municipal portions must be clarified before excavation begins.
Sewer line and excavation →A crawlspace, garage, exterior wall or poorly insulated pipe can increase the risk of freezing. Reduced flow, a dry faucet or visible frost calls for prompt attention without using a direct flame.

Choose the service that matches what you observe. If you are unsure whether the job requires cleaning, inspection or repair, describe the affected fixtures and how often the problem occurs.

The diagnosis must distinguish a private blockage, a failed protective device and a situation that may involve the municipal network.
