Quick Checks Before You Call

Slow drain

Run water at a second fixture

Turn on a nearby sink or tub. If only one drain is slow, it is likely a single-fixture clog. If multiple drains gurgle or a floor drain rises, the main line is restricted.

clogged sink

Try a hand auger or a plunger

Use a cup plunger for sinks or a flange plunger for toilets, or a 3–6 ft hand auger. Do not pour chemical cleaners. They can damage finishes and make safe service harder.

runnin Toilet

Check the toilet flapper and fill valve

If the toilet runs or has a weak flush, make sure the flapper seals and the fill valve is not stuck. Adjust the chain and water level if needed.

No hot water

Verify water heater power or pilot

Confirm the breaker or switch is on for electric. For gas, check the pilot or ignition status. Make sure the temperature and pressure relief valve is not discharging.

fixture leak

ISOLATE THE FIXTURE SUPPLY

Turn the small valve under the sink or behind the toilet fully clockwise to shut water to that one fixture only. If the valve is seized or starts dripping, don’t force it.

main shut-off

Know your main shut-off

Locate the home’s main water valve beside the meter. If a leak worsens, close it to stop the flow. Follow our “How to shut off the main water valve” guide

Protection for Basements

Backwater Valve installed

Backwater Valve

Stop sewer water from coming back through your floor drain during storms. We size and install city-approved valves and help you with the Hamilton rebate.

Sump Pump + Battery Backup

Keep groundwater out even when the power fails. We test your pump, size the backup, and leave you with clear next steps.

Hamilton basements see two risks—sewer surges and rising groundwater. A backwater valve and a reliable sump pump with battery backup protect finishes and lower flood costs.

FAQ – HAMILTON PLUMBERS

Yes. We provide same-day home plumbing across Hamilton, Ancaster, Dundas, Stoney Creek, Burlington, Grimsby, Binbrook, and Caledonia with a written installed scope before any work starts.

Run water at a second fixture. If several fixtures gurgle or a floor drain backs up, the main line is restricted. If only one drain is slow, it is usually a local trap or branch.

We do not recommend them. Chemicals can etch finishes, harm older piping, and create a hazard for anyone working on the line. A plunger or hand auger is the safer first step.

Most issues come from a worn flapper, a sticky fill valve, or an improper water level. Replacing the flapper and tuning the fill valve usually restores a strong, quiet flush.

Confirm power or pilot, reset tripped breakers, and make sure the gas valve is on. If the relief valve is discharging or there is a leak, shut power or gas and call for service.

If backups repeat, if there are roots, or if you are buying a home, a camera shows cracks, bellies, and connections so we fix the cause and not only the symptom.
