What are the different sizes of bottle traps? Many folks have this question but don’t know where to find an answer.

This blog post will cover all you need about bottle traps!

I will cover the different sizes, their use, and how to choose the right one for your needs.

What is a Bottle Trap?

A bottle trap is a plumbing fixture that collects water drains from a sink, shower, or bathtub.

The water collected in the trap prevents sewer gas from entering the building through the drainpipe.

The term “bottle trap” is used because the fixture’s shape resembles a bottle.


How Many Sizes of Bottle Traps?

Bottle traps have many different sizes to fit all the needs.

The most commonly used sizes include:

  • 32mm: This is the most popular size used for most sinks. Consider this size if your sink is less than 6 inches deep.
  • 40mm: This size is used for urinals, showers, and sinks. This size would be good if you have a product that needs a bigger drainpipe.
  • 50mm: This size is used for commercial sinks, bathtubs, and other products needing a bigger drainpipe.

Now that you know the different sizes, let’s talk about the best bottle traps in each size.

Factors to Consider when Selecting a Bottle Trap Size

When choosing the right size bottle trap, there are a few factors to consider.

If you are a seller of bottle traps or an importer, then here are some factors you should consider:

  • The type of drainpipe you are selling: First of all, if you sell only one kind of drainpipe, you need to ensure that the bottle trap you offer is compatible. But if you sell multiple types of drainage pipes (PVC, ABS, cast iron, etc.), you have more flexibility and can offer a wider variety of trap sizes.
  • The size of the drainpipe: The drain size is also an essential factor to consider when selecting a bottle trap. If the drainpipe is too tiny, the trap will not fit properly and may leak. If the drainpipe is too large, the trap will not seal properly or leak.
  • The type of sink: The sink you use will also affect the size of the bottle trap you need. For example, a pedestal sink will require a different size trap than a wall-mounted sink.
  • The type of faucet: The type of faucet you use will also affect the size of the bottle trap you need. For example, a single-handle faucet will require a different size trap than a double-handle faucet.

Once you have considered these factors, you can narrow your search and choose the right size bottle trap for your needs.

Bottle Trap Vs. P Trap:

If you’re wondering which type of trap to use for your plumbing, here’s a quick overview of the differences between bottle traps and P traps.

Bottle traps are typically used for sinks and wash basins, while P traps are used for showers and baths.

The main difference is that bottle traps are shaped like a bottle, while P traps have a U-bend.

Bottle traps are more efficient at trapping water since there is less chance of water leakage. However, P traps are less likely to become blocked than bottle traps.

Bottle Trap FAQs:

Q: How does a bottle trap work?

A: A bottle trap works by using a small amount of water to create a seal around the drain pipe. This water seal prevents sewer gases and other odors from escaping into the home through the drain.

Q: Why do Botle Traps get Damaged?

A: Over time, the rubber seals in a bottle trap can become damaged or worn out, which can cause the trap to leak. Additionally, if the water level in the trap drops too low, it may no longer be able to create an effective seal. As a result, it is essential to check and clean your bottle trap regularly.

Q: What are other types of traps in plumbing?

A: There are a few other types of traps used in plumbing, which include: Floor Trap (aka Nahni Trap), Sump Pump, Grease Trap, Gully Trap, P Trap, Q Trap, Shallow trap (S Trap), Intercepting Trap. These are the most common waste pipes or plumbing traps in plumbing.
