QA with a Spokane Plumber: Tree Roots FAQ

Orangeburg pipe in Spokane, WA

As your local Spokane drain cleaning experts, we at Mainstream Plumbing get many questions from homeowners about preventing sewer line clogs. Here’s what you need to know about tree roots:

Q: What’s the biggest threat to my sewer lines?

A: Tree roots! They can sneak into even small cracks and grow, blocking your pipes completely.  Spokane’s mature trees are especially likely to cause problems.

Q: Why are tree roots so destructive?

A: They’re opportunists!  Cracked or damaged pipes are especially vulnerable. Avoid planting large, fast-growing trees near sewer lines. Prune existing trees regularly.

Q: Which trees are the worst offenders?

A: While no tree is 100% safe, some are worse than others. Here in Spokane, be wary of:

  • Ash
  • Cottonwood
  • Locust
  • Maples (including red, silver, and sugar)
  • Poplar
  • Sweetgum
  • Sycamore
  • Willow

Q: How can landscaping help protect my sewer lines?

  • Replace water-seeking trees every 8-10 years before their roots reach the pipes.
  • Plant slow-growing trees near sewer lines.
  • Consider root barriers when installing new sewer lines.

Q: What if I already have roots in my pipes?

  • Call a professional! Mainstream Plumbing can help. There are temporary solutions, but professional cleaning is best.

Don’t wait until it’s too late! Contact Mainstream Plumbing today for expert tree root removal and sewer line cleaning.

Here are some additional tips:

  • Some customers have success with foaming root killers from hardware stores. Be careful, these can be harsh on the environment.
  • Spring and fall are prime times for root growth, so be extra vigilant during these seasons.

Remember, professional help is the best way to ensure your sewer lines stay clear of tree roots.
