House traps were originally designed to prevent sewer odors from escaping your drains and re-entering your home. A typical house trap (also known as a “p-trap”) looks like a “U” in your plumbing line. Essentially, water gets caught in the curved pipe and blocks gasses from drifting back through the system.
A blocked p-trap will cause water backflow to occur. The first sign that your p-trap is clogged is when the water in your sink takes longer than average to flow down the sink.
The easiest way to find the sewer trap is to locate the fresh air inlet pipe which is typically located near the front wall of your house. The fresh air inlet outlet is also on the outside front or the side of your home, and it will be exposed and covered by a grating.
Routine inspection of a sewer line can catch damaged sewer traps before they become an issue. A replacement can cost $100 for parts plus an additional $45 to $200 per hour for labor. In total, replacing a sewer trap can cost between $1,500 and $3,000.
A house trap, also referred to as a building trap or sewer trap, is a plumbing feature that was fairly standard in older homes but is generally considered outdated now. The house trap is a curved pipe of the sewer line that holds a small amount of water at all times.

Trenchless sewer repairs, such as pipe lining or pipe bursting, are typically 30-40% less expensive than traditional excavation and less invasive. Traditional excavation, which involves digging a trench to access the damaged pipe, is usually more expensive and can cause significant damage to your yard.
Expert Recommendations for Sewer Line Cleaning
We recommend homeowners schedule sewer line cleaning every 18 to 24 months to prevent buildup and clogs. Regular cleanings help avoid costly repairs and extend the life of your plumbing system.
For instance, residential sewer line depth ranges from 18 to 30 inches. However, city sewer line depths are different. Your city's sewer lines must always be deeper than the deepest residential pipe to allow waste to flow downhill. As such, these lines can go as deep as needed.
House traps were a common plumbing device in homes that were built up to about 1989. Basically, it's a U-shaped piece of pipe that is installed with the sewer line that runs underground from the home to the municipal sewage main.

P-traps, named after their shape, contain a u-shaped bend that filters wastewater as it enters a plumbing system. The trap is connected to a sink, bathtub, and shower with a J-bend on one end and exits into your drainage system. The J-bend is the section of the p-trap that resembles the letter J.

S trap: An S trap is a type of waste trap shaped like the letter S. The trap is made up of an S-shaped pipe connected to the drainpipe on one end and the outlet pipe on the other. When wastewater flows into the trap, it fills the S-shaped pipe, creating a barrier that prevents sewer gases from entering the building.
You can check by inserting a snake into the shower's drain. If you hit water soon after entering the drain, you most likely have a P-trap. It may also be visible with a flashlight, depending on the shower's design. If you do not have one, you'll want to leave the installation to a qualified plumber.
