A lot can go wrong in a home that can be costly to repair. When showing a home or viewing it with clients, there are some common issues realtors can make buyers aware of when it comes to plumbing.

Every homeowner should at least have a basic understanding of problems that could arise as well as the appropriate professional to remedy the situation. It’s helpful for your clients to have a trusted plumber to call when there’s a problem — sometimes even with small issues because things can quickly escalate.

Following are some plumbing problems your clients may come across. It’s important to have an expert on hand to pinpoint and fix any issues before water damage occurs. On top of dealing with that, they could even end up paying more in water bills thanks to deficiencies.

7 plumbing issues that may require a plumber’s expertise

1. Dripping faucets. Faucets and fixtures in sinks, bathtubs, showers and dishwashers should not drip when turned off. Dripping is often due to worn seals and can lead to higher water bills over time. Addressing these drips promptly can save money and prevent further wear.

2. Leaky pipes. Leaks can occur in both visible and hidden pipes, leading to water damage, mould growth and increased utility costs. A plumber is needed to locate the source of leaks, especially those hidden behind walls or under floors, and to repair or replace the affected pipes.

3. Running toilets. Toilets should not continue to run after flushing. A running toilet indicates an internal leak, which wastes water and increases bills. If jiggling the handle is necessary, components like the flapper valve, float or fill tube may need adjustment or replacement.

4. Clogged or slow-draining sinks. Kitchen sinks often clog due to food debris and bathroom sinks frequently become clogged with hair. While some clogs can be cleared with over-the-counter solutions, persistent issues require professional attention. Using strainers can help prevent clogs by keeping debris out of drains.

5. Sewer line backups. A clogged sewer line can cause significant damage by backing up raw sewage into the home. This issue is often due to tree roots or broken pipes and requires specialized equipment and expertise to diagnose and resolve.

6. Water heater issues. Leaks, sediment buildup or faulty thermostats can lead to inefficient heating or complete failure. A plumber can assess the water heater’s condition and perform necessary repairs or replacements to ensure it operates safely and efficiently.

7. Outdated or banned piping. In older homes, you may find galvanized or polybutylene pipes, which are prone to corrosion and can lead to lead contamination or system failure. Replacing these pipes with modern materials is a complex task that requires a plumber’s expertise.

Other issues

Additional common plumbing issues our inspectors often come across include: 

• No water shut-offs — essential for quickly stopping water flow in emergencies
• No backflow valve — prevents contaminated water from entering the clean water supply
• Improper fittings — can lead to leaks or inefficient water flow
• Incorrect dishwasher connections — improperly installed drain lines can cause leaks
• Loose toilets — can lead to leaks and water damage
• Poor water pressure — may be a sign of underlying plumbing issues

Encouraging your clients to schedule annual home maintenance inspections can help identify these issues early. Home inspectors can spot problems and may recommend local plumbing experts to address any concerns.

An annual inspection is also a great time for homeowners to bring up any issues they’ve noticed throughout the year that weren’t remedied right away. Preventative maintenance not only provides peace of mind, but it can also save money by addressing potential problems before they become major issues.
