Older homes have charm, character, and a unique style that many homeowners love. But along with those historic details often comes aging plumbing systems that can create headaches if left unchecked. Service Plumbing & Heating regularly helps homeowners in Lynnwood and surrounding areas address plumbing issues common in older properties.
If you live in a home that’s 30, 50, or even 100 years old, here are the plumbing problems you’re most likely to encounter—and what to do about them.
1. Corroded Or Outdated Pipes
Why It Happens
Many older homes were built with galvanized steel or even lead pipes. Over time, these materials corrode, rust, and leach contaminants into your water supply.
Signs To Watch For
- Discolored or rusty-looking water
- Low water pressure
- Frequent leaks
The Fix
Repiping with modern materials like PEX or copper ensures safer water delivery and better system performance.
2. Low Water Pressure
Why It Happens
Low pressure is one of the most common complaints in older homes. Corrosion, mineral buildup, and partially clogged pipes restrict flow over the years.
Signs To Watch For
- Weak shower streams
- Faucets that barely trickle
- Appliances running inefficiently
The Fix
A professional inspection can determine if the issue is with your pipes, fixtures, or main water service line.
3. Leaky Or Failing Fixtures
Why It Happens
Decades of use can wear out faucets, toilets, and shower valves. Rubber washers harden, seals crack, and fittings loosen with age.
Signs To Watch For
- Dripping faucets
- Running toilets
- Water pooling under sinks
The Fix
Replacing outdated fixtures not only prevents water waste but also updates the look of your home.
4. Sewer Line Issues
Why It Happens
Older homes often have clay or cast-iron sewer lines that deteriorate over time. Tree roots can also invade the pipes, causing blockages and backups.
Signs To Watch For
- Frequent clogs or slow drains
- Sewage odors around the property
- Soggy patches in the yard
The Fix
Camera inspections and sewer line replacements ensure your system keeps working reliably.
5. Outdated Water Heaters
Why It Happens
Water heaters in older homes may be far past their prime. Over time, sediment buildup reduces efficiency and can even damage the tank.
Signs To Watch For
- Inconsistent hot water
- Strange noises from the tank
- Rust or leaks around the unit
The Fix
Upgrading to a modern, energy-efficient water heater, or even a tankless system, provides reliable hot water and lower utility bills.
