Neighborhoods We Serve
Crescent Park is our most frequent call for flood work — the 1920s and 30s homes near the creek sit in the zone that flooded in 1998. Old Palo Alto's gracious older homes often have basements and crawlspaces that take on water in wet winters. In Midtown and Barron Park, mid-century homes with finished lower levels need sump systems sized for the water table. College Terrace and Southgate cottages, some dating to the city's earliest days, combine aging drain lines with low-lying lots.
Sump Pump Installation in Palo Alto
A proper sump system starts below the floor: we cut a pit at the lowest point of the crawlspace or basement, set a sealed basin, and install a primary pump sized to the inflow we measure — not a generic off-the-shelf guess. The discharge line runs to daylight or the storm system with a check valve that stops backflow, and we strongly recommend a battery backup pump on a separate circuit. When the power fails during the same storm that is filling the pit, the backup is the part that saves the house.
We also address what the sump cannot fix alone. Backwater valves on the sewer lateral stop the city main from pushing sewage backward into your home during heavy storms. French drains and proper grading move surface water away from the foundation before it ever reaches the pit.
Palo Alto's Older-Home Plumbing Reality
Flood protection is the headline, but Palo Alto's housing stock brings classic older-home plumbing issues too. Pre-1960 homes in Crescent Park, Old Palo Alto, and College Terrace often still carry original supply and drain lines that have outlived their design life — and because the water here is soft, the failure mode is age and corrosion rather than scale. We see it as pinhole leaks in old copper, crumbling drain joints, and water pressure that fades as interior corrosion narrows the pipe.
Remodels add another layer. Palo Alto's constant cycle of renovation means we frequently tie new bathrooms and kitchens into 80-year-old drain stacks — work that demands careful sizing and venting so the new fixtures do not overwhelm the old system.

Frequently Asked Questions
**Does my Palo Alto home really need a sump pump?**
If your property sits near San Francisquito Creek, has a basement or below-grade living space, or has taken on water in any recent wet winter, yes. The 1998 flood damaged over a thousand homes in the Crescent Park area, and the water table in low-lying Palo Alto stays high all winter. A sump pump is inexpensive insurance against a five-figure water damage event.
What happens to my sump pump during a power outage? A standard pump stops — which is why we install battery backup systems as part of every Palo Alto sump job. The backup pump runs on a deep-cycle battery and handles the pit independently for hours.
Can a backwater valve really stop sewage from backing up? Yes. A backwater valve is a one-way gate on your sewer lateral: wastewater flows out normally, but when the city main surcharges during heavy storms, the gate closes and blocks the reverse flow. It is one of the most cost-effective flood protections for low-lying Palo Alto homes.
Is Palo Alto's soft water easier on my pipes? Considerably. Because the city moved to Hetch Hetchy supply, Palo Alto homes do not face the aggressive scaling that destroys plumbing in hard-water cities. Your pipes fail from age and corrosion instead — which means failures are more predictable and inspections more useful. An annual check of an older Palo Alto home catches most problems early.
