A trap bottle is a plumbing device that is used to prevent foul odors from entering the living space through the drain pipe. It is a small, bottle-shaped container that is installed in the drain line of a plumbing fixture, such as a sink, shower, or toilet. The trap bottle contains a small amount of water that forms a seal, or "trap", between the drain and the living space. This seal prevents sewer gases from escaping into the air and causing unpleasant odors.
Trap bottles are commonly used in buildings where the plumbing system does not have a venting system or where the venting system is inadequate. They are often used in mobile homes, RVs, and other temporary or portable structures where a traditional plumbing system is not feasible.
Trap bottles are relatively easy to install and maintain. They are typically made of plastic and can be easily removed and cleaned. However, they do need to be filled with water regularly to maintain the seal. If a trap bottle is left unused for an extended period of time, the water in the trap can evaporate, causing the seal to break and allowing foul odors to enter the living space.
There are several types of trap bottles available, including:
P-trap bottle: This is the most common type of trap bottle, and it gets its name from its shape, which resembles the letter "P". It is typically installed beneath sinks and other plumbing fixtures.
S-trap bottle: This type of trap bottle is similar to the P-trap bottle, but it has a different shape that resembles the letter "S". It is also typically installed beneath sinks and other plumbing fixtures.
Bottle trap: This type of trap bottle is a standalone unit that is designed to be installed in the drain line. It is typically used in situations where a traditional P-trap or S-trap is not feasible, such as in tight spaces or in temporary or portable structures.
Drum trap bottle: This type of trap bottle is a large, cylindrical container that is typically used in older plumbing systems. It is less common today because it can be difficult to clean and maintain.
The main differences between these types of trap bottles are their shape, size, and where they are installed in the plumbing system. P-trap and S-trap bottles are typically installed beneath sinks and other fixtures, while bottle traps and drum traps can be installed in a variety of locations. Additionally, some types of trap bottles may be easier to clean and maintain than others.
Installing a trap bottle in your plumbing system is a relatively simple process that can typically be completed in just a few steps. Here is a general guide to installing a trap bottle:
Turn off the water supply to the plumbing fixture where you will be installing the trap bottle. This can typically be done by turning a valve located beneath the sink or fixture.
Remove the existing trap from the drain line. This will typically involve unscrewing the slip nuts that connect the trap to the drain pipe and the plumbing fixture.
Install the trap bottle in the drain line. This will typically involve inserting the inlet and outlet connections of the trap bottle into the drain pipe and the plumbing fixture and securing them with slip nuts.
Fill the trap bottle with water to create a seal between the drain and the living space.
Turn the water supply back on and check for leaks. If you notice any leaks, tighten the slip nuts or replace any damaged components.
Run water through the plumbing fixture to ensure that the trap bottle is working properly.
It is important to note that the specific installation process for a trap bottle may vary depending on the type of trap bottle and the plumbing fixture where it is being installed.
