Your toilet should not need a second flush.

Watch for these early warning signs:

• It keeps running after you flush
• The bowl fills slowly
• You hear bubbling sounds
• Water appears around the base

Small toilet problems can turn into leaks, clogs, or floor damage. It is better to check them early.

Don’t Ignore These Signs Before Heating Season Starts 🍂

Your heating system may not be running much yet, but now is a good time to pay attention to how it performs when you do turn it on.

Watch for signs like unusual noises, uneven temperatures from room to room, trouble reaching the temperature set on your thermostat, or unusual odours that don’t go away.

Catching something unusual early can give you time to have it checked before colder weather arrives and your heating system is working every day.
