Plumbing smells

How important is water in keeping smells in the sewer and away from your property?

A trap can loose its water seal by a syphonic action.

• By the use of another plumbing fixture.
• Poor design or incorrect venting of the property drainage system.
• Oscillation - Wind effect from outside breeze or storm.

There are many possible ways to loose the important trap seal, but the most common is caused by the wind outside or non use of the fixture.

When you return to your property after a holiday or a few days away or on a windy day you may get a smell in your home from the drain.

Quick tip: Run the water in the basin, shower, kitchen sink and check your tiolet pan water seal.

A few seconds of water will stop the smell and insure an adequate seal. You can open the windows to add fresh air.

PS: clear out your drains every few years to help minimise other trap seal problems.
