No hot water? Know what to check before calling a plumber
Losing hot water can disrupt the whole household. Before assuming the tank needs replacing, note what has changed: is there no hot water anywhere, just less than usual, or a puddle around the heater? Those details help a plumbing or HVAC professional understand the situation without guessing.
Stop and get urgent help if you notice danger
Gas smell: Leave the area without operating switches or equipment. Contact your gas utility's emergency number or emergency services from a safe place. Do not attempt repairs. Water near electrical equipment: Stay clear of the wet area and get professional help; do not touch electrical switches or the panel while standing in water. Active major leak: If you can reach a safe, clearly identified water shutoff without entering a hazardous area, turn it off and call for urgent plumbing help.
What kind of hot-water problem do you have?
- No hot water anywhere: Tell the contractor whether the heater uses electricity, natural gas, or another energy source, and whether there are any error messages or unusual noises.
- Hot water runs out quickly: Note whether this happens at every fixture, how many people recently used hot water, and whether it began suddenly.
- Only one tap is affected: Note which fixture and whether the other taps still receive hot water. The problem may not be at the heater itself.
- Water under the tank: Keep people away from electricity and note where the water appears; a leak can come from pipes, fittings, drainage or the tank, and needs assessment.
- Temperature swings or discoloured water: Tell the professional when it happens, whether all fixtures are affected, and whether it is a new issue.
Safe observations to make before calling
You do not have to diagnose the appliance. Write down the approximate age and brand if they are visible without moving covers, whether the home still has cold water, which taps are affected and whether there is visible moisture. Follow the manufacturer's user instructions only. Do not open gas or electrical compartments, bypass safety controls or attempt gas fitting.
Repair or replacement?
Ask for an explanation of the diagnosed fault, a written repair estimate, and—if replacement is proposed—an itemized quote. Compare the water-heater type and capacity, removal and disposal, any needed venting or electrical work, warranty, permit responsibility and timing. A symptom by itself does not establish that the heater must be replaced.
Do you need a permit in Langley?
The Township of Langley's plumbing permit guide says its plumbing permit is not required for replacing hot-water tanks, or for repairing leaks and obstructions in pipes and drains. However, it does require plumbing permits for other work such as installing or changing parts of the plumbing system, adding fixtures or replacing waterlines. Those Township rules should not be assumed to apply automatically to an address in the City of Langley.
Gas is a separate issue. Technical Safety BC's gas-permit guidance says gas-appliance installation or replacement—including a gas water heater—and gas piping or vent alterations require a gas permit. A hired licensed contractor applies for that permit. Technical Safety BC or a municipality may be the issuing authority, depending on your address. In other words, a plumbing-permit exemption does not mean a gas water-heater replacement is permit-free.
Technical Safety BC also describes eligibility restrictions for homeowner gas permits and inspection requests, including at least one inspection request within 180 days of permit issue. Confirm requirements with the authority handling your property before work begins.
A common permit misunderstanding
“The Township says I don't need a plumbing permit for a replacement hot-water tank, so there are no permits.” That conclusion can be wrong for a gas appliance. The Township plumbing guide addresses the plumbing permit. Technical Safety BC's July 2025 gas alteration bulletin separately confirms that changing regulated gas equipment or systems requires the appropriate installation permit before work begins. Tell the company whether your existing heater is gas or electric and ask which approvals apply.
What details help you compare two estimates?
Ask each company to identify the exact heater model and capacity, explain any differences in installation scope and state whether the price includes venting adjustments, removal and disposal, required permits, taxes and warranty. A cheaper quote with major items excluded may not actually cost less. Make sure the company explains who will respond if a leak or heating problem occurs after installation.
What should you ask the plumber or heating contractor?
- What evidence supports repairing versus replacing this heater?
- Is the quoted equipment suitable for the household's hot-water needs?
- Does the quote include removal, disposal, labour, taxes, connections and any vent or electrical changes?
- If gas work is involved, who obtains the permit and arranges inspections?
- What warranties cover the unit and the installation work?
How much will it cost?
There is no reliable single Langley price for all hot-water problems. A leak at a fitting, a failed component and a complete appliance replacement involve different scopes.

For questions about callout fees and hourly rates, see our BC plumbing repair cost guide; its published rates are examples from individual companies, not quotes for water heaters.
