Internachi certified professional inspector
One of the biggest concerns I see from potential new homeowners is the cost of dealing with sewer problems. While it can be very expensive to repair a sewer line, the biggest concern is having sewage backing up into the home and being unable to use water until repairs are completed. In many cases I recommend getting the main sewer line scoped to check for clogs or damage before a home is purchased.
While it is always a good idea to get a sewer inspection done, I generally tailor my advice based on the individual property being inspected. As a rule of thumb, every home over 20 years old should have the sewer lines checked but it is especially critical to get an inspection done for the following two scenarios:
The Property has Large Trees
It goes without saying that large trees have large roots, roughly equivalent to the span of the branches. The biggest concern is that roots can pierce and slowly destroy the sewer lines, leading to sewer backup or a sewage leak on the property.
The Home is Older, Especially a Home Built in the Mid 70s or Earlier
There are several common-sense reasons older homes are more likely to have sewer failures, but the main concern I have is no-corrode piping, otherwise known as orangeburg. Contrary to the name, these pipes are black, not orange and are named after Orangeburg, New York where they were originally manufactured. They were generally used residentially from the early 1940s to 1974 and are made of compressed wood fibres and tar. Not only are they at the end of the expected 50-year lifespan but this type of pipe tends to collapse and cause complete sewer blockage and is a cheaply made, poor quality material overall.
It is never my intention to alarm or scare homeowners or home buyers, but the simple fact is that no-corrode piping needs to be replaced if discovered: if it hasn’t failed already the chances of failure in the coming years is very high and it is a miracle there are still functioning orangeburg systems in 2021. The only way to determine if you have it is to have the sewer system scoped. This is a service that I am looking to add to our company in the near future but in the meantime, there are several plumbing contractors that can perform a sewer inspection.
Here are a few warning signs that it may be time for an inspection:
Finding a problem early before it escalates to a complete blockage or sewer pipe collapse will allow to time to plan a repair on your schedule while avoiding the nightmare that is sewage backup into a home. I have seen the results of sewage going where it shouldn't, and I promise you it isn’t something you ever want to see or smell.
