Drain Pipe size from Toilet to Septic Tank ??
Our toilet stops up frequently. Sometimes seemingly for no reason.
I peeked under the house a couple of weeks back and noticed
that the main drain pipe is only 3 inches PVC. And the
pipe from the toilet to the main drain line is also 3 inch.
It is 3 inch pipe all the way to the foundation wall.
From there it changes to a 4 inch pipe and goes to the
septic tank. Shouldn't it be 4 inch pipe all the way.
I think somebody skimped on pipe to save a few dollars.
Wouldn't amount to much savings but would cost me plenty to fix.
What do y'all say about it.
