Drain Cleaning & Rooter Services:
From clogged drains to backed-up pipes, we offer rooter services that clear blockages quickly and efficiently.
Leak Detection & Repair:
We find hidden leaks and fix them before they cause costly water damage.
Sewer Line Services:
We provide fast sewer line repairs and replacements for your home or business.
Water Heater Services:
Expert installation and repair for all types of water heaters.
Drain Cleaning & Rooter Services:
Slow drains and repeat clogs usually come from one of three sources: grease and food in a kitchen line, hair and soap in a bathroom line, or tree roots pushing into a cracked clay sewer lateral — a pattern we see constantly in older neighborhoods like Rose Garden, Willow Glen, and Naglee Park.
Leak Detection & Repair:
Hidden leaks waste water and quietly damage foundations for months before they surface. Using thermal imaging and acoustic equipment, we pinpoint leaks behind walls and under slabs without tearing your home apart.
Water Heater Services:
Water heaters fail early in the South Bay because our hard water accelerates sediment and scale, often cutting a tank's life to seven to nine years instead of the rated ten to twelve.
Gas Line Services:
From a suspected gas leak to a new line for a range, firepit, or ADU, gas work is not a DIY job. Our licensed team handles gas line repair, installation, and safety inspections to code across the South Bay.
Emergency Plumbing:
A burst supply line, a sewer backup, a flooding water heater, or the smell of gas — these get worse every minute they go unaddressed. Our emergency plumbers in the South Bay answer around the clock and dispatch same-day during business hours, arriving stocked to fix most problems on the first visit.
Sewer Line Services:
Most pre-1970 South Bay homes still run on clay or cast-iron sewer laterals, and both fail predictably: clay cracks and invites roots, cast iron corrodes from the inside.
Plumbing Built for San Jose Homes
San Jose plumbing isn’t like anywhere else, and the right plumber knows it. Much of the city is served by hard to very hard water — groundwater in the Santa Clara Valley commonly tests around 11 to 26 grains per gallon, well above the 7-gpg “hard” threshold. That mineral load is why San Jose water heaters wear out faster, why faucets and shower doors scale up, and why pipes in older neighborhoods narrow over time.
Add in the valley’s clay soils, decades-old clay sewer laterals, mature trees sending roots into sewer lines, and occasional seismic shifting, and you get a very specific set of problems: recurring drain clogs, slab leaks under the foundation, and sewer backups. We’ve worked on these homes long enough to fix the cause, not just the symptom.

What Counts as a Plumbing Emergency?
If any of these are happening, call a 24/7 emergency plumber right away — waiting usually means more damage and a bigger bill:
- A burst or leaking pipe you can’t stop
- Sewage backing up into tubs, toilets, or floor drains
- The smell of gas (leave and call from outside)
- No hot water from a leaking or failed water heater
- An overflowing toilet that won’t stop
- A major slab or under-foundation leak
Quick “what to do right now” steps:
- 1.Shut off the water — the fixture valve for a small leak, the main shutoff for anything major.
- 2.If it’s a water heater or gas issue, turn off the unit’s power or gas supply.
- 3.Contain the water with towels or a bucket to limit damage.
- 4.Call Valle’s Plumbing at (408) 840-5932 and describe what’s happening.

Frequently Asked Questions
How much does a plumber cost in San Jose?
There’s no set rate — pricing depends on the specific job, the parts required, and how accessible the problem is. Valle’s Plumbing gives you a clear, upfront estimate after a quick assessment, before any work starts, and the estimate is free.
Do you offer 24/7 emergency plumbing in San Jose?
Yes. We respond to plumbing emergencies day and night across San Jose and the South Bay — burst pipes, sewage backups, gas smells, and water heater failures. Call (408) 840-5932 any time.
What is considered a plumbing emergency?
Burst or uncontrollable leaking pipes, sewage backups, the smell of gas, an overflowing toilet, a failed water heater, or a slab leak all count as emergencies. If water or gas is escaping and you can’t stop it, shut off the supply and call a plumber right away.
How much does drain cleaning cost in San Jose?
Cost depends on the severity of the clog, whether it’s a single line or a main line issue, and whether hydro jetting is needed. We inspect first and give you a firm price before starting — no guessing over the phone.
Is it worth repairing a water heater or should I replace it?
If your water heater is under 8–10 years old and the issue is a thermostat, valve, or element, repair is usually worth it. Older tanks with leaks or heavy sediment — common in San Jose’s hard water — are often more cost-effective to replace. We’ll give you an honest recommendation, not an upsell.
Why does San Jose water cause so many plumbing problems?
Much of San Jose has hard to very hard water (often 11–26 grains per gallon). Those minerals build up as scale, shortening the life of water heaters, narrowing pipes, and clogging fixtures — which is why local homes see more sediment, scaling, and drain issues.
What areas do you serve?
We serve all of San Jose — including Willow Glen, Almaden Valley, Cambrian, Rose Garden, Evergreen, Berryessa, and North San Jose — plus Santa Clara, Campbell, Los Gatos, Saratoga, and Los Altos.
Are you licensed and insured?
Yes. Valle’s Plumbing & Rooter is fully licensed and insured (California CSLB C-36 plumbing contractor, license #1146987). You’re protected, and the work is code-compliant.
