Testing, repair and replacement of backflow preventers that protect drinking water, with test reports prepared for your water provider.
A backflow preventer is a safety device on your irrigation line. Its job is to stop water from the irrigation system, which may contain fertilizer, soil and bacteria, from flowing backward into the drinking water supply. Many water providers require one on irrigation systems and ask owners to have it tested on a schedule. Devices can fail from freezing, debris and wear, and a failed device is a health risk and a compliance problem.
We test backflow preventers with calibrated gauges and follow the procedure for the type of device installed, whether a pressure vacuum breaker, a double check assembly or a reduced pressure zone device. We repair devices by replacing worn seals, springs and check parts, or we recommend replacement if repair is not sensible. We prepare the test report in the format many providers ask for, and explain what your local requirements are so you stay in good standing. We also advise on insulation and placement to protect the device from freezing.
Tests follow the right procedure for each type of device, using calibrated gauges.
Worn seals and check parts are replaced, and we advise when replacing the device makes more sense.

You tell us about your yard and what you want, a new system, a repair or a tune-up, and we set a visit that fits your day.
We walk the property, find the water source and valves, test pressure and flow, look at every head and zone and take photos of anything of note.
We explain your options for zones, heads, drip, controllers and savings, sketch the layout and give you a written scope with clear timing and pricing.
We arrange for underground utilities to be located, protect the lawn, driveways and beds and mark every head, valve and pipe run before we dig.
We install or repair pipe, valves, heads and wiring with the right parts for each zone, flush the lines and keep the site tidy as we work.
We program the controller, test every zone with you, walk through watering and winterizing in plain steps and set a reminder for your next check.
It keeps water from your irrigation system from flowing backward into the drinking water supply.
Many providers require testing once a year. Check your provider, and we can remind you each year.
We repair it or recommend replacement, retest it and prepare the report.
