Why Hamilton Homeowners Choose ProFlow for Tankless Water Heater Installation

Every community has unique plumbing characteristics shaped by housing age, soil conditions, and local infrastructure. Our technicians are experienced with the specific challenges that local homeowners face — from the properties in Westdale to the homes in Hamilton Mountain.

Lead Water Service Lines

Hamilton has one of Ontario's highest rates of lead service lines due to its large stock of pre-war housing. Even with the city's corrosion control treatment, lead levels can spike when water sits in pipes overnight. We perform lead testing, full service line replacement, and coordinate with the City of Hamilton's replacement program to minimize cost and disruption.

Local Tip

Heritage homes in Dundas and Westdale — many built before 1940 — commonly have lead water service lines connecting the house to the city main. Hamilton's ongoing lead service line replacement program is gradually addressing this, but the portion on private property is the homeowner's responsibility. We recommend testing your water for lead, especially if you have young children. If replacement is needed, we coordinate with the city program so both sides of the connection are upgraded at the same time.

Every ProFlow technician is licensed through the Technical Standards and Safety Authority and carries full insurance coverage. All work meets or exceeds Ontario Building Code requirements.
