The basics of sewer inspections:
- If an older sewer pipe is still carrying waste with no leakage, there is no reason to replace it.
- Most main lines need to be cleaned every three to five years as part of normal maintenance.
- Make sure you “clear” the line before you inspect it.
Keeping your equipment clean is a must!
Types of pipe you might find:
- Wooden stave
- These pipelines became popular after a notable 1883 installation in Denver, Colorado.
- It almost looks like a hollowed-out tree.
- The most common you will run up against.
- They were used from 1880 – 1930.
- The average life is 50 to 60 years.
- The downfall of clay is root intrusion and cracking. Roots are a big issue and will need to be taken care of year after year.
- They are resistant to chemicals.
- The first sanitary sewer pipe in the US made of concrete was installed in 1942.
- Most were installed between 1930 – 1970.
- Most are four-foot to six-foot sections.
- Cast iron
- It should last between 75 – 100 years.
- In commercial buildings the lifespan is only about 30 – 50 years.
- Why is it shorter in commercial buildings? Chemicals are a big part of it. Plus, more water will wear it out quicker.
- Detergents, chemical drain openers, soil conditions, and grease will shorten the life expectancy of the cast iron.
- They were used from 1860 – 1970.
- Fiber pipe made from layers of wood pulp and pitch pressed together. The pipe is sealed with coal tar.
- It is the shortest-lived sewer line material with a life expectancy of 30-50 years.
- Starting around 1975, plastic piping emerged as a low-cost easy-to-repair alternative to metal materials.
- ABS = acrylonitrile butadiene styrene.
- They are designed to last for long periods, typically over 100 years.
- There are two colors, green and white.
Cleaning the pipe:
- Pressure jetting
- Hydro jetting
- When you recommend cleaning to a homebuyer, it is essential to know which one will be best
- The pressure of water will not break the pipe
What equipment do you need?
- A good quality sewer camera
- Pipe wrench
- Water pump pliers
- Disposable gloves
- Roll of paper towels
- Drop cloth
- Safety glasses
- Dish soap – whenever you run your camera, use dish soap down the line
What makes a good camera?
- The more lighting, the better.
- A line counter.
- Self-leveling head.
- You do not need all the bells and whistles. For instance, you do not need a camera head that turns side to side or a self-contained unit (suitcase style).
- Troy uses www.inspectorcameras.com and www.ridged.com.
What does this cost, and what can I make?
- It costs around $4,500 – $7,500 to get started.
- In 2019, we did 1,157 sewer inspections – an added $231,400 in revenues.
- $200 per sewer.
- How do you set your price?
- Call around in your area and find out what everyone is charging.
