Do tree roots seek out plumbing systems?

Tree roots do not actually search out plumbing systems, but take advantage of any weak points through which moisture escapes. They perceive moisture leaking from breaks in the pipes or loose joints. This moisture is an invitation to grow in dry soil. The roots grow toward the source, invading every opening they can find. Guards can be placed to stop these invasions before they happen.

Root barriers offer physical protection when installed correctly. Place heavy plastic membranes between trees and pipes. Depth is important; bury obstacles to a depth of 60cm, at an outward angle. The effectiveness of barriers is such that the chances of root penetration are reduced by about 90% if they are installed properly. Barriers should be checked yearly for signs of root penetration.

Too much moisture prevents roots from exploring too far. Fix dripping faucets right away. Grade the turf away from areas around pipes. Install French drains where water collects, especially if the soil is dry, as there is no incentive for roots to grow. This is a simple thing, but it keeps most invasions from starting.

Chemical root inhibitors provide temporary assistance. The use of copper sulfate creates hostile areas around plumbing, which last from three to six months before reapplication is needed. Foam barriers expand in the cracks of the plumbing. These should only be used in addition to some physical barrier, not as replacements.

You usually must consider professional removal when roots have invaded. Hydro-jetting can effectively clear minor intrusions. Replacing a section of pipe can fix damaged sections of pipe. It is essential to always consult an Arborist if you consider cutting roots. Cutting over 25% of the roots can compromise the tree's stability.
