DIAGNOSIS BEFORE A DECISIONTank, connections, capacity and access assessed

WATER + ELECTRICITYKeep away if water is approaching an electrical source.

Leaking water heater

Make the area safe before looking for the failed part.

A leak can come from a connection, the temperature and pressure relief valve, the drain valve or the tank. Its source completely changes the decision. A perforated tank cannot be repaired reliably, so water heater replacement is normally required.

  1. 01

    Stay away from water near electrical equipment

    Do not walk through water to reach the panel, water heater or an outlet.

  2. 02

    Turn off power only if access is dry and safe

    Use the breaker identified for the water heater. If you are unsure, do not touch it.

  3. 03

    Close the water supply if it is accessible

    The cold-water shutoff is usually on the upper supply pipe. Do not force a seized valve.

  4. 04

    Call and describe the leak precisely

    Tell us whether the water is coming from above, a valve, the bottom of the tank or a visible connection.

Repair or replace

Water heater repair: the symptom points to what should be checked.

A water heater repair may be suitable for certain connections or replaceable components. A leaking tank, advanced corrosion or multiple failures may make replacement the more sensible option.

0 L

No hot water

The breaker, power supply, thermostats, elements and safety devices may need to be checked. Electrical work must be handled by an appropriately qualified person.

½

Lukewarm water or reduced supply

A failed element, a setting, high demand or an undersized tank can produce similar symptoms.

DRP

Leak at a connection

Depending on its condition, an upper connection, valve or joint can sometimes be repaired without replacing the entire tank.

CUV

Water coming from the tank

A leak through the tank or near its base usually indicates that the tank has lost its integrity.

TPR

Discharge from the relief valve

Temperature, pressure, expansion or a defective valve are possible causes. Never cap its discharge pipe.

SND

Unusual noises

Sediment, material expansion or an operating component can create different sounds. The source must be confirmed.

Identify the problem correctly

Repair or replacement: not every sign of water comes from the tank.

Locating the moisture helps avoid condemning the tank too quickly. If it is safe, dry the area and observe where the water returns without removing any panels.

  • Above: hot- or cold-water connections, shutoff valve or condensation.
  • On the side: temperature and pressure relief valve or its discharge pipe.
  • Near the bottom: drain valve, condensation or water running down from a higher point.
  • Under the tank: possible corrosion or perforation that should be assessed promptly.

Do not remove electrical panels and never disable the relief valve.

Choosing capacity

40- or 60-gallon hot water tank: start with peak demand.

Household size helps, but it is not enough. Baths, long showers, back-to-back schedules, the washing machine, dishwasher and recovery rate all affect real-world comfort.

40GALLONS

More moderate demand

May be suitable when simultaneous demand is limited, space is tight and routines are predictable.

  • Measure the available diameter and height
  • Confirm the rating and existing electrical supply
  • Review periods of back-to-back hot-water use
60GALLONS

Greater reserve and demand

May better suit larger or closely spaced demand peaks if access, space and the existing installation are compatible.

  • Check passage through doors and stairways
  • Confirm clearances and connection height
  • Compare recovery rate, not only tank size

Water heater installation

A successful water heater installation is planned around the tank.

The new unit must fit through the access path, the old tank must be removed, and the connections and safety discharge must be adapted. Replacement involves more than choosing a capacity from a label.

Have the installation assessed →
  1. 01

    Confirm the model and capacity

    Dimensions, rating, warranty, household demand and compatibility with the existing installation.

  2. 02

    Check access

    Stairs, doors, turns, ceiling height, panel clearance and the route for removing the old tank.

  3. 03

    Isolate and drain the old unit

    Shut off the supplies, control the drainage and protect surfaces during handling.

  4. 04

    Prepare the connections

    Cold inlet, hot outlet, shutoff valve, relief valve, discharge piping and drain pan when required by the configuration.

  5. 05

    Fill before energizing

    The tank must be full and purged of air before power is supplied to the heating elements.

  6. 06

    Test and explain

    Check the connections, operation and safety discharge, then explain the relevant instructions to the owner.

Plumbing requirement

The relief valve protects the tank only when its discharge is correctly arranged.

The RBQ specifies that replacing a storage water heater in an existing building must comply with the Construction Code. Among other requirements, the relief-valve discharge pipe must point downward and discharge indirectly to a permitted destination for the configuration.

It must not be capped, arbitrarily reduced or directed where discharge would create a hazard. The correct solution depends on the floor drain, pit, pan and existing connections.

VAL

Accessible shutoff valve

The cold-water supply must be isolatable without forcing an inaccessible or damaged valve.

TPR

Relief valve left operational

The temperature and pressure relief valve remains an essential safety device.

DRN

Planned discharge route

The pipe route and discharge point must suit the actual installation.

ELE

Electrical coordination

The circuit, breaker and electrical work are subject to the applicable requirements and qualifications.

60°C

STORAGE TEMPERATURE

Temperature and safety

Do not lower the tank setting as a makeshift solution to scalding risk.

Québec public-health guidance recommends storing water at 60 °C to limit Legionella growth. Scalding risk should instead be controlled with the appropriate devices near points of use, according to the applicable requirements.

Do not adjust thermostats or anti-scald devices at random. Have the system checked if the water is excessively hot, not hot enough or inconsistent.

Water heater installation cost

A useful estimate separates the appliance from the installation conditions.

The cost of a water heater installation or replacement does not depend only on a 40- or 60-gallon capacity. The photos and details below help establish the actual scope instead of relying on an incomplete number.

Selected unit

Capacity, technology, warranty, dimensions, rating and model availability.

Access and handling

Floor, stairs, turns, door width and surface protection.

Existing connections

Pipe position, shutoff valve, relief valve, discharge route and required modifications.

Draining and removal

Condition of the old tank, drain valve, removal route and disposal of the unit.

Drain pan and discharge

Floor configuration, proximity to a floor drain and the compliant solution required.

Separate electrical work

A circuit or electrical-connection change may require separate coordination.

Frequently asked questions

Before water heater installation, repair or replacement.

The precise answer depends on the model, the source of the problem and the existing installation.

Speak with a plumber
Can an electric water heater that no longer heats be repaired?

Sometimes. The power supply, thermostats, elements and safety devices must be checked. Plumbing and electrical work can require different qualifications.

Does a leaking water heater always need replacement?

Not when the leak comes from a connection or replaceable part and the tank remains sound. A leak from the tank itself generally leads to replacement.

How do I choose between a 40- and 60-gallon water heater?

Consider peak use, the number and duration of showers, baths, appliances, available space, electrical rating and the model’s recovery rate.

How much does water heater installation cost?

The model, capacity, access, removal, connections, discharge arrangement and related work affect the price. Photos and the rating plate help define the scope.

Why does my hot water run out faster than before?

An element, thermostat, increased demand, sediment or insufficient capacity can cause this symptom. A diagnosis helps avoid replacing the tank without reason.

What temperature should a water heater be set to?

Québec public-health guidance recommends a storage temperature of 60 °C to limit Legionella growth. Appropriate devices at points of use are used to manage scalding risk.

Who performs the electrical connection?

Electrical work must be performed by a person holding the applicable qualifications. Mention any planned rating, circuit or panel change when you call.

Should I buy the water heater before calling?

Not necessarily. Confirming capacity, dimensions, rating, access and connections before purchase reduces the risk of choosing an incompatible unit.

What should I do if the tank is leaking heavily?

Stay away from water near electrical equipment, turn off power only if access is dry and safe, close the water supply if possible and call 514 312-1521.
