Years of Experience in Residential Lawn Irrigation System Installation in the Metro Seattle Area

Our customized irrigation solutions include all design, excavation, piping, and controller/timer installation, all fully permitted, and meeting the highest construction and efficiency standards. Whether you need sprinkler system for your 3-acre lawn or for your 10 × 20 foot garden, DLH Landscaping will use the highest-quality equipment (e.g., Schedule 80 PVC piping and connectors, and highly durable emitters and sprinklers). This is extremely important to avoid damage, breakage, or leaks when the pipe is accidently hit by homeowners who are digging holes for new plantings around their property.

Your new irrigation system will be designed based on your home’s current water output capacity: How many gallons of water per minute are available, and what is your property’s water pressure? One rule of thumb in quality irrigation design is that sprinklers can use only 70% of the residence’s water capacity at any time to ensure adequate flow for other typical home needs (laundry, showers, etc).

Based on careful measurements of the irrigation area, we calculate the number of emitters needed and the length of piping required. How far is the lawn or garden from the water source? Sprinkler nozzle sizes are also dependent on the size of the area needed to irrigate.

We install backflow regulators on all our residential projects. At DLH Landscaping, we only use programmable Hunter or Rainbird controllers, for the highest quality and durability, and the greatest flexibility in automatic scheduling and manual control of your new, state-of-the-art lawn irrigation system.
