Sewer repair; if you stop to think about it, you are baffled by how a plumber could spot problems in a sewer drain. After all, these drains, pipes, and tunnels are so dark it is nearly impossible. For a trained plumber, however, it is not that difficult at all. Here is how a plumber will spot problems in your sewer drains and pipes, and how he/she goes about fixing the problems.
Scopes, Scopes, and More Scopes
Plumbers have, at their disposal, all kinds of scopes. Borescopes, drain scopes, pipe scopes, etc., and that is how they get a peek at what is going on. All of the scopes they use have both a camera and a very bright light on the ends of their scopes so that the plumbers can easily see every square inch of pipe.
Articulating borescopes are especially useful because plumbers can get the heads to articulate in just about every direction, including backwards. What might have been missed on the first pass down can be caught when the borescope's head is turned backward on itself. If the plumber thought he/she saw something, the scopes can turn in that direction to look.
Trouble lights are so named because they are used to examine car engines in trouble, or flag down trains for help. These single-bulb, caged lights can be carried like torches, and the bulbs are protected against accidental breakage. They are mostly waterproof, making them ideal for work around water and sewers. They are also extremely bright and can shine a lot of light down a sewer drain to reveal any problems there.
Seeing in Larger Sewer Pipes
In larger sewer pipes, plumbers can use flashlights to look around. The walls of these sewer pipes are often highly reflective because of the moisture and waste that has slidden around on them. The plumbers use special filters on their flashlights to reduce the reflection without reducing the brightness. When the plumber discovers something amiss in the pipe, he or she removes the filter to examine the problem with brighter light and greater clarity. Then the plumber makes the necessary repairs.
With the Right Equipment, Nothing Escapes the Plumber
When a plumber has all of the above equipment and lighting options, it is just a matter of a game of peek-a-boo. The plumber will search until the repair issue pops into view. The equipment continues to do its job until the repairs are complete.
