Eliminate Sewer Gas Odors: A Step-by-Step Guide to Fixing Dry P-Traps

If you’ve noticed unpleasant sewer gas odours in your home, the culprit might be a dry P-trap. Learning how to fix a dry P-trap can save you from these nasty smells and keep your living space fresh. In this guide, we’ll walk you through identifying dry P-traps in sinks and floor drains and provide easy steps to rehydrate them.

Understanding P-Traps and Their Importance

You can find the P-trap right underneath your sink or floor drains. 

A P-trap’s primary function is to hold a small amount of water, creating a seal that prevents harmful sewer gases from entering your home. When this water evaporates, it results in a dry P-trap, allowing those foul odours to escape.

Identifying a Dry P-Trap

You need to identify the issue before figuring out how to fix a dry P-trap. Here are the signs to look out for:

• Persistent sewer gas odours near sinks or floor drains.
• Drains that gurgle or make unusual sounds.
• Infrequently used fixtures, such as guest bathrooms or utility sinks, are familiar places for dry P-traps.

How to Fix a Dry P-Trap: Step-by-Step Instructions

Once you’ve identified the dry P-trap, rehydrating it is simple.

To rehydrate a dry P-trap, follow these simple steps:

1. Locate the Affected P-Trap

Check all sinks, bathtubs, and floor drains with the most pungent odour. Confirm that the P-trap is indeed dry by looking for a lack of water in the bend of the pipe.

2. Pour Water into the P-Trap

Slowly pour about a gallon of water into the drain. This will refill the trap and recreate the seal to block sewer gases.

3. Add Mineral Oil (Optional)

For long-term prevention, consider adding a small amount of mineral oil on top of the water in the P-trap. The oil will float and slow down the evaporation process, keeping your P-trap hydrated longer.

4. Use the Fixture Regularly

Regular usage can prevent P-traps from drying out. Make it a habit to run water through infrequently used drains at least once a week.

Preventing Future Dry P-Traps

• Regular Maintenance: Ensure all fixtures are used regularly to keep P-traps filled with water.

• Check for Leaks: A leaking P-trap can also cause it to dry out. Inspect and repair any leaks promptly.

• Install Trap Primers: These devices automatically add water to the P-trap, preventing it from drying out.
