Answer 1

You are going to have to look under the home, it is generally 3 inch pipe, but it could be even white colored, just depends on what is available to whom ever set it up. There are going to be several hookups to this pipe from other drains, and these could be different sizes, depending on what kind of drain. For a sink it will only be about 11/2 inches. Just be careful if it is septic system you may have to have that cleaned out because it is not leeching properly. That would cause the backup in the other drains.

Remove a piece of skirting so you can look under the home. Its a 3" pipe under the home... usually black, tho I have seen a few light green. It should slope from where it connects to your home, down to the main connect. It should NOT have any 'low spots', or 'humps' in the line, the drop should be even, and steady. Any high or low spots in the fall of the pipe are locations where it could block up.

Now, where that pipe connects up under your home, is called the 'main drop' and is usually connected to, or near, one of the toilets in the home. If you have a second bath, then there is also a second drain line, this one is located inside the underbelly. This line runs from the other bath, to the main drop. This one is also 3" diameter, again, usually black. This drain line is usually strapped to the floor joists, and sagging is not normally a problem with it.

While you are looking at your pipe.. check the elbow fittings. Many of the older homes have what are called 'sharp' 90's....most building codes today call for a 'soft' 90 degree connecting elbow. The 'soft' 90 has a longer sweep to the curve, which helps keeps the waste moving.

Good Luck

Look for the toilet drain, it should be straight out from that, maybe ten feet. Run a rod down and slightly tap on it, you'll be able to follow it this way to the end.
