Wellington Plumber: How Heavy Rain Can Affect Your Plumbing – Laser Plumbing Wellington East

Wellington Plumber: How Heavy Rain Can Affect Your Plumbing – Laser Plumbing Wellington East

Wellington’s unpredictable weather and heavy rainfall can have a significant impact on your plumbing and drainage system. From burst pipes to blocked drains, excessive rainwater can overwhelm your plumbing system, leading to costly damage if not addressed promptly.

At Laser Plumbing Wellington East, we provide expert plumbing inspection and repair services to help homeowners and businesses prevent and fix plumbing issues caused by heavy rain.

Here are the most common plumbing problems that occur due to heavy rain in Wellington:


1. Burst Pipes Due to Ground Shifting

During heavy rainfall, the ground absorbs excess water, causing soil movement. As the soil shifts, underground pipes may experience increased pressure, leading to cracks or even pipe bursts.

Why It Happens:

  • Heavy rain softens the soil, allowing rocks and tree roots to shift and press against underground pipes.
  • If pipes are already old or weak, they become more susceptible to rupturing under pressure.

Solution: If you experience low water pressure, unusual noises in your pipes, or water pooling in your yard, it’s time to call a professional plumber to assess the damage.


2. Clogged Drains & Blocked Pipes

One of the biggest plumbing issues after heavy rain is blocked drains. Excess rainwater can carry leaves, dirt, and debris into your drainage system, blocking water flow.

Signs of a Blocked Drain:

  • Water drains slowly from sinks, bathtubs, and outdoor drains.
  • Gurgling sounds from your pipes or toilet.
  • Overflowing gutters and downpipes during rainstorms.

Solution: Regularly clean your gutters and drains to prevent blockages. If your drains are slow or blocked, a plumber with a CCTV drain inspection can help identify and remove obstructions.


3. Outdoor Flooding from Blocked Drains

After a heavy downpour, stormwater drains can become overwhelmed, causing water to pool around your home. This excess water can seep into your foundation, leading to structural damage and mould growth.

Solution: If you notice standing water around your home, it’s crucial to have your stormwater drainage system inspected. A plumber can clear blockages and ensure proper drainage.


4. Increased Pressure on Underground Pipes

As the rain saturates the ground, underground pipes experience extra pressure from shifting soil, tree roots, and moving debris. This can cause pipe fractures, leaks, or complete collapses.

Warning Signs:

  • Sudden water pressure drops inside your home.
  • Wet patches in your yard or driveway.
  • Unexplained high water bills (indicating an underground leak).

Solution: If you suspect underground pipe damage, a professional plumber can perform a leak detection test and recommend necessary repairs.
