10 Common Plumbing Issues and How to Prevent Them

Plumbing issues can range from minor inconveniences to major problems that require immediate attention. At Service Plumbing and Heating, we’ve helped countless homeowners and businesses across Seattle, Shoreline, Lynnwood, Bellevue, and Kirkland deal with these challenges. 

1. Clogged Drains – Clogged drains are one of the most common issues, often caused by an accumulation of hair, soap, grease, and food particles. Over time, these materials build up, restricting the flow of water. To prevent clogs, it’s important to use drain covers to catch debris and avoid pouring grease down your kitchen sink. Regularly flushing your drains with hot water can also help reduce buildup, keeping your pipes clear and preventing blockages.

2. Leaky Faucets – A leaky faucet might seem like a minor annoyance, but it can waste hundreds of gallons of water over time, increasing your utility bills. Typically, leaks occur when washers or seals wear out, and while these parts are easily replaceable, the problem can sometimes point to deeper issues. Scheduling regular plumbing check-ups and promptly fixing even small leaks can prevent water waste and future complications.

3. Running Toilets – Running toilets are a surprisingly common problem, often caused by a faulty flapper or valve inside the tank. A toilet that won’t stop running can waste up to 200 gallons of water a day. You can perform a simple test by adding food coloring to the toilet tank; if the color appears in the bowl without flushing, you have a leak. Fortunately, replacing the flapper or valve is usually a straightforward fix.

4. Low Water Pressure – Low water pressure can make simple tasks like showering or doing dishes frustrating. This issue can be due to sediment buildup in the pipes, corroded plumbing, or problems with your water supply. Cleaning faucet aerators regularly and checking for hidden leaks are simple preventative measures. In some cases, installing a water softener can help reduce mineral buildup in pipes, which is a common cause of low pressure in areas with hard water.

5. Slow Draining Sinks – Much like clogged drains, slow-draining sinks are typically caused by buildup in the pipes. Food particles, soap, and grease can accumulate over time, reducing water flow. To prevent this, avoid disposing of food or oil in the sink and perform routine maintenance such as flushing with hot water and baking soda to keep things flowing smoothly.

6. Water Heater Issues – A malfunctioning water heater is a common issue, especially in homes with older units. Problems range from inadequate hot water to strange noises coming from the tank. Sediment buildup is often to blame, and it can significantly reduce your water heater’s efficiency. Flushing the tank annually can help extend the life of your unit and prevent unexpected breakdowns, especially during cold Seattle winters when hot water is crucial.

7. Burst Pipes – During the colder months, especially in Seattle’s winter climate, pipes are at risk of freezing and bursting. Burst pipes can cause significant water damage and lead to costly repairs. Insulating your pipes, particularly those in unheated areas like basements or garages, can prevent freezing. On especially cold nights, allowing faucets to drip slightly helps keep water moving and reduces the risk of frozen pipes.

8. Leaking Pipes – Leaking pipes often go unnoticed until they cause visible damage. These leaks are frequently caused by corrosion, high water pressure, or damage to the pipe. Scheduling regular plumbing inspections can catch leaks early, saving you from expensive repairs and preventing potential water damage to your property.

9. Sump Pump Failure – Sump pumps are essential for homes in areas prone to flooding, like parts of the Pacific Northwest. Sump pump failure, usually caused by a clog or mechanical malfunction, can lead to water damage in basements or crawl spaces. Regular maintenance, including clearing debris from the sump pit and testing the pump, ensures it functions when you need it most.

10. Sewer System Backup – A sewer system backup is one of the more unpleasant plumbing problems and is often caused by tree roots, debris, or blockages in the sewer line. Avoid flushing anything other than toilet paper and schedule routine inspections of your sewer lines to prevent backups. In some cases, installing a backwater valve can help protect your home from future backups.
