Before Covering With Mulch

Mulch easily disguises flush lids and boxes. Know what you are burying.

What is about to happen?

A thick layer of bark or wood mulch is being spread across garden beds, foundation plantings, or large yard expanses.

What hidden system could be affected?

Irrigation valve boxes, downspout pop-up emitters, cleanouts for french drains, and sometimes even low-profile septic risers.

What clues or records may help?

Check previous landscaping plans or run the irrigation system manually to locate the valves before the mulch crew arrives.

What does the visible surface not guarantee?

A completely flat soil bed does not mean it is empty. Lids often sink over the years and sit just below the natural soil grade.

What becomes expensive if wrong?

If an irrigation zone gets stuck on, the valve must be found to turn it off. If it is buried under 4 inches of fresh mulch, you will have to dig blindly, ruining the landscaping and paying hourly for the search.

When should local confirmation happen?

Before the mulch is dumped. If you suspect buried access points, have a landscaper or irrigation tech raise the boxes to the new grade level.

Need to verify?

Contact a Irrigation Specialist or Landscaper before you cover.
