The plumbing system for these fixtures normally consists of a trap. An S-trap or P-trap can be used depending on where the toilet bowl will be installed.

Functions of a trap

Water will accumulate inside the trap and serve as a barrier to keep out gases and pests. Any large object that accidentally enters the drain pipe may potentially become stuck in the trap.

S-trap

An S-trap toilet bowl is the most basic kind of trap used in plumbing systems. The trap is formed like the letter S and was previously utilized in practically all plumbing systems.

When an S-trap toilet bowl like the American Standard Acacia SupaSleek CL20075-6DASGCBT 1-piece toilet bowl is full, water builds up in the bend and prevents the gases from escaping. However, if the S-trap is not in use for an extended period of time, the water inside may evaporate. This can then create a hole through which the hazardous gases from the sewage system may enter the home. The problem may be quickly resolved by adding some water to the sink or toilet bowl that is linked to the S-trap.

P-trap

In modern homes and buildings, the P-trap toilet bowl is more commonly used since it eliminates the majority of problems caused by the S-trap toilet bowl. The P-trap toilet bowl is curved which causes it to go up and down. The waste gases will then exit through the vents. A P-trap that has been properly installed will likely survive any condition.
