Signs of Tree Roots in Plumbing Pipes & How to Fix Them

If your home has an older sewer system, the risk of tree root infiltration is high. But, even newer pipes aren’t completely safe. Roots are always searching for moisture and the smallest crack in a pipe is like an open invitation. Once they get in, they grow fast, leading to nasty blockages, damaged pipes and, worst, pipe collapse.

So how would you know if tree roots are messing with your plumbing? But more importantly, how would you stop tree roots from causing plumbing problems before they lead to serious damage?

Understanding Why There Are Tree Roots in Plumbing Pipes

Tree roots in plumbing pipes don’t invade by accident. They're constantly searching for water and nutrients. So when roots detect moisture from a tiny crack or joint in a pipe, they push their way in. Once inside, they feed on water and organic waste, growing thicker and spreading bigger over time.

As they expand, they create dense blockages that slow or even stop water flow. The pressure can cause pipes to crack, collapse or burst, which can result in messy, expensive repairs. Older clay and concrete pipes are especially vulnerable, but even PVC pipes aren’t completely safe.

Signs of Tree Roots Plumbing Problems

You don’t have to dig up your yard to figure out if roots are invading your plumbing. There are clear signs of tree roots plumbing problems that can tip you off, such as:

Slow Drains

If your sink, bathtub or toilet is draining slowly, roots might be partially blocking your pipes.

Sinkholes

Tree root damage can lead to underground leaks. Over time, this erodes the soil, creating depressions or even full-blown sinkholes in your yard. If you notice unexpected soft spots or dips, it could be a sign of serious pipe trouble.

Blocked and Destroyed Piping

A root-filled pipe can eventually collapse and lead to sewage backups or burst pipes. If you notice frequent blockages, even after using a plunger or drain cleaner, tree roots might be the real culprit.

Foul Odour

Smelling a musty or rotten smell around your drains? That could be sewer gas escaping through cracks caused by tree roots. If the smell is particularly strong outdoors or near your plumbing vents, don’t ignore it.

Reduced Water Flow

Low water pressure is annoying, but it is also a big red flag. When roots grow inside pipes, they restrict the flow of water, leading to weak taps, slow-filling toilets and uneven pressure.

Gurgling Noises

If you hear odd gurgling or bubbling sounds from your drains, air might be getting trapped due to partial blockages. This often happens when tree roots start interfering with normal water flow.

Increase in Water Bills

A sudden spike in your water bill with no clear reason? Hidden leaks from root damage could be wasting water, driving up costs without you even realising it.
