Added a flow-monitoring shutoff valve to the water main so a burst line shuts itself off instead of running until someone notices.

“We had a leak from our upstairs toilet that damaged our first-floor ceiling. Umed arrived right on time, was very professional and careful with our home, and took the time to thoroughly assess the situation. He explained three repair options, clearly outlining the pros, cons, and warranty for each. I highly recommend Umed for honest, skilled, and reliable plumbing work.”
“Umed came out and diagnosed the issue with my Rinnai tankless water heater quickly and efficiently. Communication was excellent — he worked with Rinnai to sort out the warranty and got the parts covered. The intermittent cold water issue is gone, and it was caught just in time. I’ll definitely ask for Umed again.”
“Umed was a miracle worker! He came in right when we needed him and finished his work quickly, efficiently, and in a knowledgeable and friendly manner. I would be more than happy to recommend his services — he’ll have my business for as long as I live here in the Bay Area!”
A few things we run into on Sunnyvale calls again and again.
Sunnyvale has many Eichler homes on concrete slabs, some with in-slab radiant piping. Leaks there need careful leak detection and re-routing, not jackhammering.
Cherry Chase and Birdland ranch homes from the 1950s–60s may still have original drain lines — a camera inspection shows their condition before they fail.
Much of Sunnyvale gets moderately hard to hard water. We test hardness for free at a water treatment consultation and recommend a softener or filtration only when it makes sense.
BAAQMD has adopted zero-NOx standards for certain new water heaters, and additional amendments are currently under consideration. Requirements and effective dates vary by equipment type and may change. PEAK Home Service can help Sunnyvale homeowners compare gas, tankless and heat-pump options based on the rules, rebates and equipment available at the time of installation.
Per BAAQMD, a working water heater can stay in service until it burns out or needs replacement. The rule applies when new equipment is sold or installed.
Requirements are based on the water heater's BTU rating and date of manufacture — not on your home's age or a property sale.
The BAAQMD Board is scheduled to consider Rule 9-6 amendments on November 4, 2026. If approved, they would add some exemptions and extend the compliance date.
We'll explain which gas, tankless and heat-pump options fit your home, space and electrical setup under the rules in effect when you install.
Regulatory information last reviewed: October 2026. Verify current requirements with BAAQMD before installation. Rebate amounts, eligibility and funding are set by each program and change often — we check current programs with you before any work begins.
