Pitch on a sewer pipe is a measure of how far a pipe should fall over a certain distance on a horizontal run. A proper pitch is what allows the contents of the pipe to keep moving. If you’re experiencing problems with waste leaving your home, this might be an issue and you should call us. Proper pitch on a sewer pipe is between 1/8th of an inch and ½ inch per foot. For example a four foot long pipe should be ½ inch higher on the front than the end of the pipe.
Many plumbing problems can occur if your pipes weren’t installed with the proper pitch. Water will just sit idle in a pipe that’s completely level. Furthermore, if the water is not moving enough or moving in the proper direction, back-ups will occur far more frequently. This isn’t even the worst of it .
Older homes where drainage and sewer pipes are cast iron may have the worst case scenario. Cast iron rusts when sitting under water. Over time a cast iron pipe full of water will simply rot out through the bottom causing a major sewer leak.
If you have frequent back-ups call us immediately. We’ll have one of our dependable plumbers come out to see that your pipes have the proper pitch for your home.
North Texas, we just had the coldest weather we’ve had in twenty years this February. I’m sure my daughter, (who knows the dangers of frozen pipes by the way), isn’t the only one who didn’t consider that this year was a different situation than years past. Those single digit and below temperatures can really stop things up tight, potentially causing some significant damage when pipes decide to thaw.
You’ve asked this question before, I’m sure. Believe me when I tell you we understand that you’d rather fix a plumbing leak yourself instead of spending the money on a plumber. So many times we’re called out to jobs that were quite intensive – and expensive – because the call was delayed for that reason.
