Difference between P-Trap and S-Trap
Main difference
The main difference between P-trap and S-trap is that the length of bottom tubing used in P-traps is p-shaped while the length of bottom tubing used in S-traps is S-shaped.
P-Trap vs S-Trap
P-traps are the traps that are p-shaped, that is, when the water passes through these pipes, the little water is reserved, while the bottom traps used in S-traps are S-shaped. In the P-trap, the sewage is reserved for a small interval, while in the s-trap the sewage is reserved.

The p-trap is the preferred one these days, while the S-trap is generally used less nowadays. The P-trap is smaller, while the S-trap is slightly larger than the normal P-trap. In the P-trap, there is no need for the sink to save water, however, in the s-trap, water is needed in the sink to drain the debris. The P-trap is a new technique for the drainage system, while the S-trap was installed in an older build. There is no odor in the p-trap installation due to the small water reservoir in the sink, while in the tarpaulin the odors from the drains are reserved in the pipes that cause different diseases.
