Plumbing issues refer to problems that arise in a building's water supply and drainage systems. Common issues include leaks, clogged drains, and low water pressure. These problems can lead to water damage, mold growth, and increased utility bills if not addressed promptly. Homeowners often encounter plumbing issues due to aging pipes, improper installation, or blockages caused by debris. Regular maintenance, such as clearing out drain traps and checking faucets, can help prevent these problems. When issues arise, it is advisable to consult a professional plumber for effective repairs and solutions.
