If you're purchasing a home, you'll be given the chance to have the home inspected to tell you if there is anything wrong with it before you buy it. If you decide to bring in a plumber, be aware that they will look at the following things for you.
Outgoing Sewer Lines
One place your plumber will want to look closely at is the plumbing line heading out to the main sewer. That's because these pipes are known to have issues with tree roots getting into the pipe and causing clogs. Some materials, like drain pipes made with clay tiles, can even be on the verge of collapsing due to tree roots. A plumber will look closely at these pipes by putting a camera down the drain cleanout. They can let you know if tree roots will be a problem and is the pipe may need repair in the future.
It's not possible to inspect interior plumbing with a camera, which means other techniques must be used. Your plumber may want to use a thermal camera that will let them see pipes that located behind the walls of the home. They can detect leaks by seeing a temperature change behind a wall, which means that water is leaking out of the pipe in that particular spot. This can give you a heads up about a potential expensive repair.
The home's water heater is one appliance that should be inspected in a couple of ways. A plumber can look at the age of the water heater and let you know if it is close to the end of its lifespan and if you might need to think about a new hot water tank installation. They will also inspect for rust to let you know if it has the potential to leak. While there are many tests that cannot be done with a simple inspection, it can let you know about major problems.
The plumbing vent is how the dangerous sewer gases leave your home, and also how air gets pulled in to give you water pressure. They will check this vent by looking for potential obstructions, which can be done by sticking a camera into it.
Many aspects of a home's plumbing can be expensive to repair, so if an issue is discovered, you should negotiate with the owner of the home to repair it or give you a credit at closing. The cost of using a plumber to perform an inspection can easily pay for itself after you move into the house.
