Water heater and fixture installation

Replacing a water heater that's leaking or past its useful life (roughly 10 to 12 years for a standard tank) is routine work, but in older housing stock the pressure drop often starts further upstream, in galvanized pipe. A plumber handling your request can check both before proposing a straight tank swap.

Fixtures in houses built before the 1980s frequently have shutoff valves that no longer turn, corroded stuck open. A plumber handling your request can replace them with quarter-turn valves any time the plumber is already changing a faucet, sink or toilet, so the next repair doesn't start with a whole-house shutoff.

A plumber handling your request can assess a tankless water heater installation for basement renovations where space is tight, sized to what the existing pipe can actually deliver rather than the nameplate number.

A water heater's age is on the manufacturer's label on the tank, not just "we've had it a while." A manufacture date at or past 10 to 12 years, combined with rust at the base or a weeping pressure-relief valve, points to a tank near the end of its life. A repair — swapping an element or a valve — still makes sense on a tank under 8 years old; past that, the risk of the tank itself leaking within months makes replacement more sensible than a part changed on a tank that's going to fail anyway.

Request a quote for a standard tank, supplied and installed, including the existing venting — a flue shared with the furnace costs more to tie into than a direct vent — and on access to the spot. In post-war West Island bungalows the water heater usually sits in an open mechanical room, while in an older duplex basement the tight space around the unit adds handling time.

Hooking a new water heater up to a service line that's still galvanized only solves part of the problem: the tank will deliver its full output, but the water still has to travel through the section narrowed by corrosion before it reaches the tap. A plumber handling your request can flag this before proposing a water-heater-only swap, so the client isn't disappointed by pressure that stays weak despite a brand-new unit.

A tankless water heater needs a dedicated vent and, on a gas line, sometimes a larger gas meter — two things to check before confirming a price, since neither is ever the same from one house to the next. The conversion costs more than a straight tank swap, but it frees up the floor space the old tank used to take, a real gain in a basement being finished for living space.

When the flue shared with the furnace is no longer enough to safely vent a gas water heater — often the case once the furnace itself has been replaced with a high-efficiency model that no longer uses that flue — a power-vent unit becomes necessary. It costs more up front, but it lets the water heater sit away from an exterior wall and avoids redoing the whole chimney.

A water heater installed behind a backflow preventer on the water service — increasingly common with recent replacements — needs an expansion tank to absorb the pressure created by water heating inside a closed system. A plumber handling your request can check for this during a replacement, because a closed system without an expansion tank wears out the pressure-relief valve early and can leave it weeping continuously.

Draining the tank once a year and checking the sacrificial anode after the warranty period can push the useful life past the 10-to-12-year average, but few homeowners actually do it in practice — a tank that's never maintained rarely makes it to 15 years.
