Frequently Asked Questions

 

Do I Need a Plumber to Install P Trap Pal?

No. P Trap Pal is designed for simple DIY installation and can typically be installed in just a few minutes without special tools. Most homeowners can install it by hand using the existing sink drain assembly.

P Trap Pal is installed above the P-trap and below the sink drain, creating an additional barrier against sewer odors and insects that can enter through a dry P-trap.

For step-by-step guidance, visit our Installation Instructions page.

What Is a Dry P-Trap?

A P-trap is the curved section of pipe located beneath most sinks. Its purpose is to hold water, which creates a seal that helps prevent sewer gas from entering your home.

When that water evaporates or is lost, the P-trap becomes "dry." A dry P-trap can allow sewer odors, drain flies, fruit flies, and other insects to enter through the drain.

Dry P-traps are especially common in:

  • Guest bathrooms
  • Vacation homes
  • Rental properties
  • Model homes
  • Seasonal homes
  • Unused sinks

Why Does the Water in My P-Trap Dry Out?

The most common cause is evaporation from lack of use. If a sink is not used regularly, the water seal in the P-trap can gradually disappear.

Other causes include:

  • Improper plumbing venting
  • Wind oscillation
  • Capillary action
  • Siphoning
  • Extended vacancies

This is why many homeowners notice sewer odors in guest bathrooms, upstairs bathrooms, vacation homes, or sinks that are rarely used.

Does P Trap Pal Prevent My P-Trap From Drying Out?

P Trap Pal helps slow the evaporation of water from the P-trap. However, its primary purpose is to help prevent sewer odors and insects from entering your home if the P-trap becomes dry.

Even when water has evaporated from the P-trap, P Trap Pal continues to provide an additional barrier between your living space and the plumbing system.

Can P Trap Pal Help Stop Sewer Odors?

Yes.

One of the most common causes of sewer odors in bathrooms, guest bathrooms, garages, and vacation homes is a dry P-trap.

P Trap Pal is designed to help block sewer gas and unpleasant drain odors from entering through the sink drain when the water seal in the P-trap is compromised.

Many customers install P Trap Pal specifically to address:

  • Guest bathroom odors
  • Sewer smells from unused sinks
  • Vacation home odors
  • Drain odors in rental properties
  • Odors in garages and utility sinks

Can P Trap Pal Help Prevent Bugs and Insects From Entering Through Drains?

Yes.

Insects can sometimes enter a home through plumbing drains, particularly when a P-trap dries out.

P Trap Pal helps create an additional barrier that may help prevent:

  • Drain flies
  • Fruit flies
  • Small insects
  • Other pests associated with plumbing systems

Many customers use P Trap Pal to address recurring bug problems in rarely used bathrooms, garages, vacation homes, and rental properties.

Can P Trap Pal Be Used Instead of a P-Trap?

No.

P Trap Pal is designed to work together with a standard P-trap, not replace it.

While some users have reported alternative installations, P Trap Pal is intended to be installed above an existing P-trap as an additional layer of protection against sewer odors and insects.

My Sink Smells Like Rotten Eggs. Can P Trap Pal Help?

Possibly.

A rotten egg smell is often caused by bacterial growth or biofilm inside plumbing components. When water flows through the drain, it can disturb that biofilm and release unpleasant odors.

Because P Trap Pal is installed above the P-trap, it can help provide an additional barrier that reduces the amount of odor entering the room through the drain opening.

Will P Trap Pal Affect Drainage?

Under normal installation conditions, water should continue to drain through the sink as intended.

P Trap Pal is engineered to allow water and normal sink debris to pass through while helping block the reverse movement of sewer gases and insects.

Always follow installation instructions and ensure your sink meets the recommended installation requirements.

Will Debris Become Stuck in P Trap Pal?

No.

P Trap Pal is designed to pass debris that would normally pass through the sink drain. If cleaning is ever required, the device can be accessed and cleaned similarly to a standard sink drain assembly.

Will P Trap Pal Fit My Sink?

P Trap Pal is designed for standard 1.5-inch sink tailpiece applications.

Before purchasing, verify your plumbing dimensions and review the installation requirements to ensure compatibility with your sink configuration.
