Common Signs Your Drains Might Be Failing
When drains start to fail, the signs aren’t always obvious — until they are. In many Christchurch homes, especially those built before the 1980s, aging clay or earthenware pipes can slowly deteriorate below the surface. Earthquakes, tree roots, shifting ground, and general wear and tear all contribute over time.
Spotting problems early can save you a major headache (and a major repair bill) later. Here are some of the most common warning signs that your drains might need attention.
1. Strange Smells in the House or Garden
Unpleasant smells are often the first hint that something’s wrong. If you’re noticing a consistent sewage smell indoors or outdoors — especially near the kitchen, laundry, or garden — it could be a sign of a cracked or broken pipe. These smells tend to linger even after cleaning, and shouldn’t be ignored.
2. Gurgling Sounds in Your Pipes
That odd gurgle when you flush the toilet or empty a sink? It could be more than just air in the line. Gurgling can mean there’s a blockage forming in the system, causing air pockets and restricted flow. It’s often an early warning that a full blockage is on the way.
3. Slow-Draining Fixtures
A single slow drain (like a bathroom sink) might be an isolated issue. But if you’re noticing multiple fixtures draining slowly — or water backing up altogether — there could be a bigger issue in the main lines. Consistent slow flow usually points to partial blockages, misaligned pipes, or damage underground.
4. Water Pooling in the Yard
Unexpected soggy patches in the lawn, especially during dry weather, can signal a leaking pipe below the surface. This is particularly common with older clay drains that have cracked or shifted. It may not always be visible pooling — sometimes it’s subtle dips, unusual grass growth, or soft soil.
5. Cracks in Driveways or Paths
Drainage issues can affect more than just the plumbing. If a damaged pipe is leaking water beneath a concrete slab, driveway, or paved area, the soil can shift over time — leading to cracks, movement, or sunken sections. This is a red flag worth investigating.
