Tree roots are a leading cause of sprinkler system damage, but homeowners can reduce their costs by knowing the signs of damage and making long-term safety choices.

Sprinkler Systems and Root Intrusion

Tree roots are a top cause of sprinkler repairs in Las Vegas, and each spring, irrigation technicians spend a great deal of time repairing lines and cutting back roots. Root intrusion is the technical term for this problem, and it can refer to roots that are squeezing the lines or penetrating them. In either case, the result is low water pressure at best and water leakage at worst.

Installing Sprinkler Lines Correctly

Measures to avoid sprinkler repair from tree roots should begin during the installation process. Arborists can estimate root depth and length over time. Using that data, installers can avoid root paths wherever possible. When it’s not possible, trenches for the lines can be dug to avoid where those roots will grow. After digging, trenches must be prepped with moisture and then allowed to sit for 48 hours.

The Prospect of Tree Removal

Trees help make a property healthier and more beautiful. Most homeowners are understandably reticent to remove them, but some trees have a root structure that’s problematic. If you’re faced with that problem, you have options other than just cutting the tree down. You can move it, replace it or both. If replacing is an option, you can choose a tree with roots that won’t interfere.

Water Pressure as a Cue

Over time, you’ll get a feel for the water pressure of your system. If you sense that pressure decreasing, try to determine the cause within your sight. If you can’t, then the problem is probably underground. There are two common signs of root intrusion. In the early stages, you may experience reduced flow at startup that’s eventually overcome. In later stages, you may notice reduced flow in the zone where the blockage is.

Scheduling Seasonal Inspections

Residential irrigation systems run hard for a season to two then are winterized and remain dormant for two seasons or more. A lot can happen during that dormant period, and that’s why you should consider a seasonal sprinkler inspection every year. An irrigation specialist can test for pressure issues you might not notice by sight and sound and avoid damage if there is a problem.
