Where does a cast iron drain pipe go?

But It was common in previous generations for builders to rout (usually cast iron) drain pipes from ground-level outside of a building into the building, under the basement floor slab, and out to the municipal sewer system. These drains were used to receive roof gutter drainage and dispose of it into the city sewers.

Why is there a trap at the bottom of my drain pipe?

The dry “trap” formed at the bottom of the piping “U” no longer serves to keep sewer gases out of the building. Watch out: sewer gases may be both unsanitary and also risk of a very serious methane gas explosion. See SEWER GAS ODORS.

How big of a coupling do you need for drain pipe?

Please note: the side that attaches to the drain pipe (black end), will not fit directly to the pipe itself, it actually attaches to a pipe fitting like a coupling, or elbow. Make sure it’s not threaded on the inside, it needs to be a 3/4” slip-on type.

How big is the tailpiece of a drain pipe?

For more modern drains, you’ll find that they have a 1 ½-inch outlet. The additional piping that is connected to the tailpiece, such as the horizontal extensions and P-trap assembly, will either be 1 ¼ and 1 ½ inches in diameter.

What happens if you have a 10 ft drain pipe?

The answer is, “They won’t.” The flush will go plop and the solid will just sit there. That is understandable for a 10-ft.-diameter pipe. But translate that mentality to just a slight increase in size for the drain. The same will occur; the larger you make the pipe, the less the solids will travel.

Is the size of a drain line a problem?

The same problem occurs in commercial plumbing systems. One plumbing contractor whispered to me to not say too much about properly sizing drain lines. He said that his service division makes a lot of money clearly those drains. “If you have them size the drain correctly the first time, I’ll lose money with less drain cleaning,” he said.

What’s the best way to line a drain pipe?

Tape Tip: Use Teflon tape or pipe joint compound on threads as needed to prevent leaking. Go ahead and put the p-trap arm in the wall and line it up with the p-trap. Thread it on but do not tighten the slip nuts. Wait until you have connected all of your pieces before tightening any of the slip nuts or adapters.
