When to Call a Plumber vs. DIY

There is a lot of plumbing advice online, and some of it is genuinely useful. A confident homeowner with the right tools can handle certain repairs without calling a professional. But there are also jobs that look simple on a YouTube video and turn into expensive disasters in real life. Here is an honest guide to help you decide.

Jobs That Are Generally Safe to DIY

**Replacing a faucet or showerhead.** If you are swapping a faucet for a new one and the supply lines and shutoff valves are in good shape, this is a manageable DIY project. Turn off the water at the local shutoff, follow the manufacturer's instructions, and take your time.

**Fixing a running toilet.** A toilet that runs constantly is usually a worn flapper or a faulty fill valve — both are inexpensive parts available at any hardware store and straightforward to replace. There are good tutorials for this, and the risk of making things worse is low.

**Unclogging a slow drain.** A plunger or a drain snake can clear most minor clogs in sinks, tubs, and toilets. Avoid chemical drain cleaners — they are hard on your pipes and rarely solve the underlying problem.

**Replacing a toilet seat or bathroom hardware.** No plumbing knowledge required. These are cosmetic changes that any homeowner can handle.

Jobs That Require a Licensed Plumber

**Water heater installation or replacement.** In Alberta, water heater installation involves gas lines or high-voltage electrical connections, and must be done by a licensed tradesperson. An improper installation is a safety hazard and will void your warranty.

**Burst or frozen pipes.** A burst pipe is an emergency that needs professional repair. Temporary patches can fail suddenly and cause far more damage. A licensed plumber will repair the pipe correctly and check for related damage.

**Anything involving gas lines.** Gas line work in Alberta requires a licensed gas fitter. Full stop. This includes moving a gas line, connecting a new gas appliance, or repairing a suspected gas leak. If you smell gas, leave the building and call your gas utility immediately.

**Sewer line issues.** A backed-up sewer line, tree root intrusion, or collapsed sewer pipe requires professional diagnosis — typically with a camera inspection — and professional repair. DIY attempts can make the problem significantly worse.

**Plumbing inside walls or under slabs.** Any time a repair requires opening walls, ceilings, or concrete, you need a licensed plumber. The risk of causing additional damage — or missing the actual problem — is too high.

**New plumbing installations.** Adding a bathroom, moving a sink, or installing a new fixture in a location that does not already have plumbing requires permits and licensed work in Alberta.

The Permit Question

Many homeowners do not realize that plumbing work in Alberta often requires a permit. Work done without a permit can create problems when you sell your home, and may void your home insurance coverage if something goes wrong. A licensed plumber will know what requires a permit and handle the paperwork.
