Imagine waking up Sunday and seeing a mini water fountain continuously spray water all over your…read morefence and concrete, and hitting the neighbor's yard too. The sprinkler control panel did bot shut down the faulty sprinkler, so its likely a mechanical issue with the control valves in the backyard that failed open. I have no idea how to DIY this so I was lucky to find Ostwald. Yep, they are a 24/7 company and were able to comr out same day in a few hours. Darvin and his helper replaced my entire sprinkler control valve system, faulty sprinkler heads, and did some excavation to fix some leaky pipes. About 3 hours total - not a straightforward job since it also involved wiring and some backyard plumbing. I have an older house so they actually had to shutoff water to the house for a few hours. Not sure why the sprinkler system does not have a separate isolation valve. Maybe it does but its not obvious. Definitely recommend Ostwald Sprinkler Repair for quick turnarounds and responsive service, even on Sundays when most other sprinkler repair companies are closed.

Our problem: We have an irrigation system with 9 valves mapping to 9 different zones on the…read moremicrocontroller. Zones 1-4 stopped working suddenly. Also our Zone 9 was disconnected and we had a separate "workaround wire" for Zone 9 which we never liked because it was a visible extraneous wire glommed on as a hack/workaround. Quote: Ramon came to our place and gave us an honest quote. No blanket solutions like "replace all the wiring", "replace all valves", "replace the controller", etc. Ramon has a device that can trace the electrical wires (from the controller to the valve) and locate the disconnect. No digging up of wires involved. Solution: Ramon showed up punctually for the appointment and found the disconnect. The previous crew had spliced bunch of wires which was susceptible to disconnection. Ramon put in the proper connectors and gave us a 5-year warranty on his work. Now all the zones are working nicely and no superfluous/extraneous wires. Ramon also replaced some sprinkler heads and drip outlets that seemed broken. Solid work and great value. Master Tech Irrigation is likely the most honest and capable crew in the Bay Area at this point.
