Is it an S Trap toilet?

Question

I currently have a low level toilet where the trap goes straight out the back of the toilet, the rises up then down at a 270 degree angle straight intot he ground. Is this what it referred to as an S trap toilet? In that case what is a P trap or other types?

Answer 1

What you've described does sound like an "S" trap. A "P" trap is most common these days. It most often has either a straight connector to go through the wall directly behind the pan or a 90 degree bend connector that can be turned to exit left, right, or downwards. Offset and flexible connectors are also used in some instances to help in lining up pan outlet to soil pipework. "S" traps are pretty redundant now as the "P" trap can be utilised for most applications, it's easier for manufacturers to just therefore make that type.

S Trap Toilet

Answer 3

The toilet you are describing has a s trap.
S traps were common in older homes or homes with out venting that come straight through the bottom of the cabinet or floor and most all residential toilets
The P trap are for when the drain goes horizontal into the wall. There are toilets that do have P traps that are mounted from the wall mainly in commercial type buildings.

Answer 4

You are not quite describing your trap correctly??!! It must go down then up then down again, which makes it an 'S' trap. A 'P' trap goes down then up then straight out the back.

Answer 5

the design you talk about is to keep the water level even with whats in the trap and not to overfill or drain out. a a p trap hold water in the drain of a sink to keep odors and gases from coming into your home.

Answer 6

An "S" trap toilet drains out the bottom.
A "P" trap toilet drains out the back.
