ToggleQuick Summary
Older homes have charm but often come with plumbing issues. From deteriorating pipes to failing fixtures, these problems can lead to costly repairs. Here’s what to look out for and how to fix them.

Pipe-Related Issues
- Old pipes made from lead, galvanised steel, or polybutylene degrade over time.
- Signs of pipe failure include low water pressure, discoloured water, and leaks.
- Pipes should be replaced every 20 years to prevent blockages and contamination.
- Regular inspections can help identify potential problems before they worsen.
How to Identify Aging Pipes
Older pipes often develop cracks and corrosion. If your water appears brown or smells odd, it may be time to replace the piping system. Professional plumbers can assess your pipes and recommend cost-effective solutions.
Choosing the Right Replacement Pipes
Modern homes use copper, PEX, or PVC pipes for durability. Replacing old pipes with these materials can improve water flow and prevent leaks.
Cost of Pipe Replacement
The cost of replacing plumbing depends on the size of the house and the type of pipes used. A full replacement may seem expensive but it prevents long-term damage.
Sewer Line Problems
Signs of a Clogged or Damaged Sewer Line
- Slow drains or gurgling noises
- Foul-smelling wastewater backing up into the house
- Soggy patches in the yard indicating a leak
Common Causes of Sewer Line Issues
Tree roots, shifting soil, or old pipe materials can lead to sewer line blockages and cracks. Regular inspections help detect these issues early.
Fixing Sewer Line Problems
Hydro jetting or trenchless pipe replacement can clear blockages without extensive digging. A professional plumber can determine the best solution.

Failing Fixtures & Connections
Why Fixtures Wear Out Over Time
Older faucets, toilets, and supply lines wear out, leading to leaks and low water pressure. Fixtures should be replaced every 10-20 years to maintain efficiency.
Warning Signs of Failing Fixtures
- Dripping faucets or constantly running toilets
- Low water pressure in sinks and showers
- Water stains under sinks or around fixtures
Upgrading to Modern Fixtures
Newer fixtures are more water-efficient and durable. Switching to high-quality materials like brass or stainless steel can extend their lifespan.
Bellied Pipes
What Are Bellied Pipes?
Over time, pipes can sag or collapse due to soil movement, restricting water flow and leading to blockages.
Signs of Bellied Pipes
- Slow drainage and recurring clogs
- Unpleasant odours coming from drains
- Gurgling noises from toilets and sinks
Solutions for Bellied Pipes
Plumbers can use trenchless pipe repair methods to fix sagging sections without major excavation.

Water Heater Problems
Signs Your Water Heater Needs Repair
- Inconsistent hot water supply
- Rusty or smelly water
- Unusual noises coming from the tank
Causes of Water Heater Issues
Sediment buildup, aging components, or faulty thermostats can cause water heaters to malfunction.
