The guys who came out on Saturday to put the drain pipes in the ground were really level headed. Or maybe they were just level heads. At any rate, they really put the plumb in plumbing.
These guys are brothers and they really had good teamwork.
Every section of pipe got two levels on it. It didn't seem like it would be that hard to make sure the drains ran downhill, so I asked them about it.
And I learned something new.
Drain pipes, especially sewer drain pipes, must drop between 1/8 and 1/4 inch for every foot they go horizontally. Any more slope than that, and the fluids rush on down leaving the solids behind. The solids sit there stranded and sort of dry out. Then the next sewage voyage does the same thing, only now you have a solid mass that attracts more solids. The cumulative effect is like a beaver dam, only a lot grosser. Eventually the pipe gets completely blocked. And that's when it really hits the fan -- or the floor or wherever it can go, because the pipe is blocked.
It can choose any one of these vertical pipes for its escape.
I know. TMI.
Look even the plumber is embarrassed.
But if I don't tell you these things, who will?
At any rate, I'm very grateful to these guys to keeping us on the straight and not-quite-level-but-ever-so-gently-sloping-downhill.
