What is a Sewer Pipe Video Inspection?
It’s a process where you call in a plumbing company or a specialist to run a video linedown your branch lines (the pipes that lead from bathtubs and faucets to the house’s sewer line) or down the house’s sewer line (the larger pipe that leads from the house to the municipal sewer line on the street). At the end of the line is a camera that lets you see the line in close-up detail.
When Would I Need an Inspection for Home Remodeling?
This would not be a frequent occurrence. But you might need a video inspection if you plan to add a bathroom or remodel your kitchen or a bathroom. Because of the greater quantities of waste water involved, you may want to inspect your sewer line to make sure that it can handle the increased needs.
Typically, though, most homeowners call in a sewer line video inspection only if there is a problem, such as a blockage that cannot be fixed by plunging, liquid drain cleaners, or sewer or drain augering.
Can I Do a Video Inspection Myself?
No. Homeowner-level video inspection scopes are far too short to inspect more than the first few feet. Not only that, these scopes probably are not auto-focusing or self-righting.By contrast, sewer video scopes and locator units owned by plumbing companies can cost upwards of $15,000. They have powerful lights; they are self-righting (the picture always stays upright); they are high-resolution; they have recording capabilities.
How Much Does an Inspection Cost?
Inspection costs greatly vary, from $99 to $300. Cheaper video line inspections may produce lower-quality images due to older equipment. These offers also may be tied to purchases of more expensive services (i.e., you may be required to purchase drain augering in return for the inexpensive video inspection.
How Far Will the Video Inspection Scope Go?
It can go as near as branch lines within the house or as far as to the point where the home’s sewer ties to the municipal sewer line, maximum being about 330 feet.
What Will I See in the Video Inspection?
If you are doing an entire sewer line video inspection, you will see a “walk-through,”leading from the trap, down through the sewer line, and up to any obstructions. If the camera can push through the blockage, it may continue through to the municipal line. Don’t expect a Hollywood movie: while resolution is high, the picture will be jerky because the line has to be manually pushed down the line.
How Can I Find the Blockage Up on Ground Level So I Know Where to Dig?
The camera unit has a transmitter. The video technician/plumber will stop the camera at the blockage point. Then he will go up to ground level and wave a locating device until the device picks up the transmission signal. This allows him to spray a paint spot at the exact point of blockage.
