Conifer Near House & Water Main: Root Risk Assessment

A homeowner planted a conifer 5 feet from the house and over the water main. At 15 feet tall, they worried about root damage to pipes and foundation.

The expert said tree roots don't damage sealed water pipes—they seek leaks. Sewer pipes (especially old clay) can be invaded. Only risk is limbs rubbing the house, easily pruned. No need to remove the tree.

Pipe Safety

• Water mains: sealed, roots can't penetrate.
• Sewer lines: roots enter only through existing cracks.
• Limbs: prune to clear house.
