Common Plumbing Problems in San Jose Homes
San Jose's water hardness depends on your neighborhood and your water company. Most of the city is served by San Jose Water, whose groundwater measures 11 to 26 grains per gallon, very hard, while its imported surface water is about 4 to 9. Homes on groundwater see heavy scale on fixtures and in water heaters.
The median home in San Jose was built in 1976, and freezing is rare. Common plumbing calls include water heater replacements, leaks from aging supply lines, and slow or clogged drains.
Find Out Which Water You Have
San Jose Water serves most of the city from a mix of groundwater (11 to 26 grains per gallon) and surface water (about 4 to 9), and some areas are served by San José Municipal Water or Great Oaks Water. Your provider's water quality report tells you which source reaches your neighborhood. Homes on groundwater are the ones that most benefit from a water softener.
Hard Groundwater
Neighborhoods served by groundwater see 11 to 26 grains per gallon, leaving heavy scale on fixtures, shower glass and inside water heaters.
Water Heater Replacement
Scale shortens tank life, and California requires replacement water heaters to be strapped or braced for earthquakes.
What Affects Plumbing Costs in San Jose
No plumber can quote a firm price before seeing the problem. These are the things that move the cost of plumbing work in San Jose.
- Hard groundwater. Homes on well-supplied water often need scaled valves and fittings replaced.
- Permits and strapping. A water heater replacement needs a permit and earthquake strapping.
- Finding the problem. Leak locating and camera inspections are separate steps, but they keep the repair itself small.
- Time of day. Many companies charge an after-hours, weekend or holiday fee.
- Permits. When a job needs one, it comes from City of San José Development Services Permit Center, and the plumber usually pulls it.
- Ask for the arrival fee before the plumber heads out, and for the repair price in writing before work starts.
How to Find a Licensed Plumber in San Jose
These checks take a few minutes and prevent most bad experiences, whichever San Jose plumber you end up hiring.
Check the California License
Plumbing contractors in California are licensed by the state. Before any work starts at your San Jose home, ask for the license number and look it up with the Contractors State License Board (CSLB).
Plumbing Work That Needs a Permit in San Jose
Adding or replacing plumbing systems or fixtures, or changing how pipes are configured, generally needs a permit. Drain, faucet, toilet or leak repairs and clearing stoppages generally don't. Single-family and duplex owners can get common plumbing permits online. A water heater replacement needs one, along with earthquake strapping.
What to Ask on the Phone
- What is the arrival window?
- Is there a service, trip or after-hours fee?
- For an emergency, will you stop the damage first and quote the permanent repair before starting it?
- What is your license number?
