You CAN'T have a p-trap under the toilet! The p-trap is built into the toilet!
A P trap exits horizontal from the back of the toilet and a S trap exits vertical from the bottom of the toilet.
Nope
The trap is in the toilet. There shouldn't be one in the drain itself.
No.. The trap is built into the toilet. It can become clogged or obstructed with debris, but if it were to collapse, your entire toilet would be gushing water everywhere.
Yes... is the short answer. The toilet has a trap in itself. You would have to be able to break out the floor and put a P trap in the existing line
A toilet has a built in trap thus NO othyer trap is needed and will cause air bound systems and many problems with improper drainage
A frost proof toilet the trap is located below the frost line
I'm assuming you are talking about a p-trap. A p-trap is a fitting that holds water to block sewer gasses from entering the building through the fixture. Every fixture with a drain has to have one in the waste. A toilet has what you would call an "s-trap" built into it. It serves the same purpose as a p-trap.
P-trap may be cracked, nuts are loose on p-trap, or check for leak above p-trap that may be dripping down on p-trap.
Who invented the p trap
Its called a P trap because if you stand the trap up and looked at it, its in the shape of the letter P
