Though you may not be able to see it, the tree roots growing underground can wreak havoc on your home’s plumbing if they find their way into your pipes.

This process, called root ingress, can cause regular blockages, slow-draining drains and even low water pressure. In extreme cases, it can even cause structural damage to your home.

Here are ten signs of tree root ingress in your drains:

  1. Gurgling Sounds: If you hear gurgling sounds from your drains, it could be a sign that tree roots have found their way into your pipes and are causing a blockage. The gurgling sound is created as the tree roots try to suck water out of the drains, which can eventually cause the pipes to clog up.
  2. Regular Blockages: If you have to unblock your drains regularly, tree roots are likely the culprit. Tree roots can easily find their way into drainage systems and can cause significant damage and blockages if left unchecked.
  3. Slow Draining Drains: Drains that drain slowly or back up easily could be another indication of tree root ingress. When tree roots grow into drainage systems, they can reduce the amount of space available for water to flow through, leading to drainage problems.
  4. Low Water Pressure: If you notice a sudden drop in water pressure, tree roots may block water flow through your pipes. When tree roots become lodged in pipes, they can reduce the space available for water flow, impacting water pressure levels.
  5. Wet Spots in Your Garden: If you notice wet spots in your garden that weren’t there before, it could mean that tree roots have broken through your pipes and are leaking water. This can not only cause damage to your property but can also be a safety hazard if the water is leaking near a pathway or the street.
  6. Mould or Mildew: If you notice mould or mildew growth around your drains, it could be due to excess moisture from leaks caused by tree roots. Mould and mildew thrive in moist environments, so if you have a leaky drain, it’s the perfect place to grow.
  7. Foundations Cracks: If you see cracks in your foundation or walls, it could be a sign of structural damage caused by tree root ingress. When tree roots grow into pipes, they can pressure the surrounding structures, causing them to crack over time.
  8. Sinkholes: In extreme cases, tree root ingress can cause sinkholes in your yard. Sinkholes are large holes in the ground that can be dangerous if you happen to step into one. They are often caused by erosion of the soil under the surface and can be a sign that your drainage system is not working correctly.
  9. Toilet Bowlbackups: If you flush your toilet and the bowl starts to back up with water, tree roots may block water flow through your sewer line. This can be a severe problem, as it can cause backups not just in your toilet but also in your sinks and showers.
  10. Sewer Line backups: One of the most obvious signs of tree root ingress is when sewage starts backing up from your drains or toilets. If you see or smell sewage in your home, it’s time to call a plumber immediately, as this could indicate a severe problem with your sewer line.
