If your tank has split open or the water coming out of the tap is brown, you need a new heater and you need the flooding stopped first. We answer the 24/7 emergency line for water heater replacement in Lafayette, CA. While you wait, shut the cold supply valve, turn off the power or gas, and keep everyone away from the wet floor.
Replacement is a bigger job than a repair, so the choices matter: fuel type, tank size, where the unit sits, and what gets upgraded while the old one is out. We explain the options in plain terms and give a clear price before work starts.
If the unit is still working and only has a bad part, a repair may cost less than a new tank. This page is for the cases where it does not. The replacement tank is installed to the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC) and the earthquake bracing standards in California Health and Safety Code 19211.
Burst tank and flooding: what to do first
A burst tank can release dozens of gallons quickly, and the water goes wherever the floor slopes.
- Close the cold supply valve on top of the heater, or the main shutoff for the house if that valve is stuck.
- Electric unit: turn off its breaker. Gas unit: turn the gas control to off.
- Gas smell? Leave, call 911, then call PG&E at 1-800-743-5000. Do not stay to mop.
- Photograph the water and the label on the tank for your insurer.
- Call us with the tank size, fuel type, and where it is installed.
Signs the old tank is finished
Rusty or cloudy hot water that clears when you run only the cold tap means the inside of the tank is corroding. Puddles under the shell, wet insulation and rust streaks near the bottom seam say the same thing.
A tank that has been repaired more than once in a short stretch is also telling you something. Parts are cheap, but each failure usually means the tank is wearing out as a whole.
Repair or replace: the decision at a glance
| Situation | Better choice | Reason |
|---|---|---|
| Leak from the tank body. | Replace | Corroded steel cannot be patched. |
| Leak at a fitting or valve. | Repair | Connectors are separate parts. |
| Old tank, rust in hot water. | Replace | Interior lining is failing. |
| Newer tank, dead element. | Repair | Part swap is simple. |
| Frequent breakdowns | Replace | Cost of repeat visits adds up. |
| Tank is too small for the household. | Replace | Size cannot be changed. |
Choosing size and fuel before the old tank comes out
Gas tanks recover quickly and keep working if the power drops, while electric tanks need only a circuit and no vent. Hybrid heat pump heaters use far less electricity but need open air space around them and a drain for condensate, so they are often a better fit for a garage than a closet.
Size by household, not by habit. A tank that is too small gives you cold showers on laundry day, and one that is too big costs more to buy and keep hot. Tell us how many people live in the house and we can match the size.
If you are thinking of going tankless, the tankless water heater page explains the extra gas and venting work.
What a replacement visit includes
The tank itself is only part of the job. A proper swap usually covers the following.
- Draining the old unit and disconnecting it safely, including the gas line or electric whip.
- New flexible water connectors and, on gas units, a new gas connector and a leak test at each joint.
- A new temperature and pressure relief valve with a discharge pipe routed to a safe spot.
- An expansion tank when the system is closed and one is needed.
- A drain pan and pan drain where the tank sits above living space.
- Seismic bracing straps under California Health and Safety Code section 19211.
- Hauling away the old tank and a hot-water test at the fixtures.
Permits and the City of Lafayette
The City of Lafayette lists plumbing and mechanical permits for water heater repair, replacement or installation at single-family homes as exempt from a building permit. That is the city's own permit page, and it applies to single-family houses. Condos, townhomes, and anything beyond a straight swap can differ, so ask the Lafayette building department before you plan on skipping paperwork.
The county handles inspections for the city, so questions about a particular address go to the building department, not to us.
Getting more years out of the next tank
The anode rod is a sacrificial metal rod that corrodes so the tank does not. Replacing it every few years, and flushing sediment from the base on a regular schedule, is the cheapest way to extend a tank's life.
EBMUD's Lafayette water is very soft at 16 mg/L hardness, so scale is less of a worry here, though soft water can use up an anode rod faster than hard water does. Check the rod instead of assuming it is fine. The EBMUD water quality report has the full numbers.
If you are in nearby Orinda, the same advice holds for EBMUD water there.
How replacement pricing is worked out
Three things move the total most: the unit you choose, the condition of the space around it, and any code upgrades the old install is missing. A tight closet, a long gas run, an out-of-date vent, or the need to add bracing or a pan all add labor.
Many homeowner policies cover sudden water damage but not the failed heater, so read your policy and ask your insurer. Call, and we will give a clear price before work starts.
Replacement questions we hear from Lafayette homeowners
Yes. We staff a 24/7 emergency line and offer same-day appointments when available. If the tank is flooding, tell the dispatcher so we can send a plumber and walk you through the shutoffs.
Often, when the replacement unit is on hand and the site is ready. Special venting, a different fuel, or a larger tank can add a day. Call and we will tell you what applies to your case.
For single-family homes, the City of Lafayette's permit page lists water heater replacement as exempt from a building permit. Rules for other property types vary, so ask the Lafayette building department.
California Health and Safety Code section 19211 requires water heaters to be braced or anchored against earthquake movement. We strap the new tank as part of the install.
The tank type, size, fuel, and the work around it. Venting, gas line changes, an expansion tank, a drain pan, and difficult access all matter. Call for a clear price before work starts.
Only while the tank is still sound. If the shell is leaking, a new rod cannot help. If the tank is healthy but older, a rod and a flush can buy time.
Still unsure what you are dealing with? Call the 24/7 line and describe it to a dispatcher.
