Check out the most common plumbing problems that are most likely to be found in older houses. It will make you aware of the potential issues that you can face later.

Old, Worn-Out Fixtures

Old faucets or fixtures may look charming, but they start to show signs of wear and tear over time. As they are exposed to natural elements, they begin to corrode. When it happens, you will notice discolored water or low pressure.

Sometimes, the fixture may start leaking and break while using, which may bring inconvenience to you. This may not look like a big issue, but it can lead to water damage costing you thousands of dollars.

Imagine a failed sink due to a rusty water line valve causing flooding in your house. It’s better to go for preventive maintenance to address general wear and tear and prevent expensive repairs later.

You can call a professional plumber to inspect the line and fixtures. They will replace the fixtures that are problematic and about to break.

Failing Sewer Lines

A sewer line is buried underground, and no one thinks of it until it fails. A failed line may result in backing wastewater up to your house and foul-smelling water all over your garden or lawn area.

As sewer lines in old houses were built ages ago, they are prone to cracking, thus forming drain clogs. Being wet areas, they also attract tree roots leading to breakage or blocking of the line. A scheduled inspection of the sewer line may prevent sewer line failure in time.

Another common plumbing problem in old plumbing is the sewer line belly. It happens when the sewer line droops downwards, obstructing the natural flow of the water. This problem occurs mainly because of foundation settlement, soil erosion, or other natural factors.

It is not easy to detect this problem as the pipes are buried underground, but you can think of a trenchless sewer line replacement to fix your failed sewer lines in a day.

Drainage Problems

After several years of flushing water, soap, food particles, and other things down the pipes in the old houses, the drainage system starts having issues. As the debris and other particles accumulate over time, they start clogging the drain and prevent the flow of the water.

Most commonly, you will face this issue in kitchen and bathroom sink drains as these areas are more susceptible to developing clogs. Kitchen sinks clog because of the food particles, fat, and grease going down the pipe. Similarly, bathroom drains clog due to soap, hair, debris, etc.

Old Pipes

Houses that were built before the 1990s feature pipes no longer approved by the U.S. building codes. If you bought a house that was renovated later, you might not find these old pipes, but you should get them inspected before any unwanted surprises.

Check for the Lead, Galvanized, and Polybutylene pipes in your old home and replace them before they fail. Lead is the most common pipe found in old houses, but it can get toxic over time. Due to this, it was banned for use.

Galvanized pipes were primarily used in houses made before the 1960s. These pipes were made of iron with a layer of zinc. But as they were susceptible to corrosion and breakage, they are no longer used. Polybutylene was widespread in houses made in the 1970s, but they are no longer manufactured and used.

Faulty Repairs By Previous Owners

If you are buying an old house, it must have gone through a lot of plumbing repairs. And this is where the problems arise. Some owners have fixed the plumbing themselves, while others have got it done from an unprofessional plumber.

Unfortunately, you will have to inherit all the faulty repairs made over time. Some problems may be minor such as unsecured pipes, but some may be expensive, such as unsafe water heaters.

Try to get all these common plumbing problems fixed by a professional plumber for your safety and prevent any costly damages to your house.

Even if the house was renovated some time ago, it is safer to get it inspected before you start living there. Consider an experienced and licensed plumber to enjoy your stay in your newly purchased house.
