Water Heater Repair & Installation in Kitchener, Waterloo & Cambridge
Reliable hot water — repaired or replaced with the right unit for your home.
Southwestern Ontario's hard water is tough on tank water heaters. Sediment accumulates at the bottom, efficiency drops, elements fail early, and tanks can rumble or leak at the base long before the sticker date suggests. When you lose hot water mid-winter or notice rusty water at the tap, you need a plumber who can diagnose the tank, not just sell a replacement.
Flowline services electric and gas storage tanks, direct vent units, and tankless systems for homes and small commercial spaces across Kitchener, Waterloo, Cambridge, Guelph, Woodstock, and Stratford. We test elements, thermostats, gas valves, venting, and relief lines; flush sediment where it makes sense; and tell you when repair is fair versus when a new, properly sized unit is the better spend.
Every installation includes code-compliant connections, expansion tank and drain pan where required, removal of the old unit, and a walkthrough of maintenance that actually extends life in hard-water country.
Signs you need water heaters
- No hot water or water that won't stay hot through a shower
- Rust-coloured hot water at taps
- Rumbling, popping, or banging from the tank
- Water pooling around the base of the heater
- Pilot light or burner issues on gas models
