Scald Prevention: Hot Water Temperature Rules in NWT Rentals

Safety & Security Northwest Territories 4 min read · published March 29, 2026 Flag of Northwest Territories

Tenants in the Northwest Territories need clear, practical information about hot water temperature rules and how to prevent scalds at home. This guide explains typical safe-temperature recommendations, the landlord's duty to provide safe hot water, what to do if water is dangerously hot, and simple steps tenants can take to measure and manage temperature in rental units. It also covers how to ask for repairs, which official forms and tribunals handle disputes, and when to seek emergency help. Written for renters, this article uses plain language and includes examples so you can confidently raise safety concerns with your landlord or file a complaint if needed.

How hot water causes scalds

Scalds happen when skin is exposed to water that is hot enough to burn within seconds. Young children, older adults, and people with limited mobility are at higher risk because thinner skin and slower reaction times increase injury risk. In rental units, dangerously high hot water can result from water heater thermostat settings, faulty mixing valves, or lack of maintenance.

Small differences in temperature greatly change how quickly skin can burn.

Safe temperature recommendations

Health agencies often recommend setting domestic hot water to a maximum of 49°C (120°F) to reduce scald risk while still allowing adequate hot water for household use. Where thermostatic mixing valves or anti-scald devices are required, they should be installed and tested regularly to keep tap and shower temperatures within safe limits.

Landlord responsibilities in the Northwest Territories

Landlords must provide and maintain a rental unit that meets basic health and safety standards, which includes safe hot water supply. If hot water is excessively hot or temperature controls are missing or broken, tenants should notify the landlord in writing and request a prompt repair. You may need to refer to the territory's residential tenancies legislation and to the official tenancy office for dispute resolution when a problem is not fixed promptly.[1][2]

Report dangerously hot water immediately and avoid using faucets or showers until temperature is checked or fixed.

How to measure and test hot water safely

Measure water temperature with a kitchen or digital thermometer. Run hot water from the tap for one minute before testing at the outlet you or family members use for bathing. Record the reading, the time, and the faucet tested. If the reading exceeds safe recommendations, inform your landlord and keep documentation.

  • Test tap and shower temperatures at the locations you and family members use most.
  • Keep dated photos or notes of readings and any correspondence with your landlord as evidence.
  • Request repairs in writing and ask for an expected completion time in your message.
Test tap water with an accurate thermometer before bathing to check temperature.

Requesting repairs and next steps

If your landlord does not fix an unsafe water temperature promptly, send a clear written request and keep a copy. If the issue is urgent, mention it is an emergency repair and ask for immediate attention. If the landlord still does not act, you can file a dispute with the territorial tenancy office or the designated tribunal for residential tenancies.[2]

When to seek emergency help

Seek urgent medical attention for any burn that is large, blisters, or involves the face, hands, feet, groin, or a very young or elderly person. If the hot water condition puts the unit at immediate risk (e.g., scald risk to a child, lack of hot water in winter), explain the urgency when you contact your landlord and the tenancy office. For emergency repair procedures and tenant responsibilities, consult the guide on Emergency Situations and Repairs: Tenant Rights and Responsibilities.

Documenting repairs and communications strengthens your case if you need formal dispute resolution.

Practical examples

Example 1: If your shower measures 55°C (131°F), photograph the thermometer reading, email the landlord requesting a repair within 48 hours, and mention that the temperature poses a scald risk for small children. If no timely response, file with the tenancy office.[3]

Example 2: If the landlord installs a thermostatic mixing valve but showers still run too hot, ask for a re-check and keep any service receipts or invoices.
