Water Heater Replacement in South Pasadena, CA
South Pasadena is full of beautiful Craftsman and Spanish-style homes — and plumbing systems that have been patched and added onto for decades. We see original galvanized supply lines, water heaters wedged into tight service porches and basements, and venting that no longer meets current code. Replacing a water heater in a home like this takes more than swapping a tank: we check gas line capacity, venting, seismic strapping, and expansion requirements so the new unit is installed correctly and works the way it should. We do the work clean, haul away the old unit, and back it with our workmanship warranty.
Fast Replacement When You Need It Most
Replacing an old tank with a qualifying tankless system may make you eligible for SoCal Gas rebates of up to $1,500. Combined with our $500 new customer discount, that's significant savings on an upgrade that pays for itself over time. We handle the install correctly the first time and give you all the documentation you need for the rebate — just ask us about current eligibility when we come out for your free estimate.
Our preferred brand for conventional tank water heaters is Bradford White — an American-made product built for professionals, not sold at big-box stores. Bradford White tanks are known for their durability, industry-leading warranties, and consistent performance in SoCal's hard-water conditions. We also install Rheem and A.O. Smith units when the situation calls for it. During your free estimate, we'll walk you through which model and size makes the most sense for your home, your hot water habits, and your budget.

What To Expect
Every water heater replacement starts with a free in-home assessment. We'll inspect your existing setup — tank location, gas or electric connection, venting configuration, and water supply lines — and confirm the right replacement unit for your home. Once you approve the estimate, we get to work. Most standard replacements are completed in a single visit: we remove the old tank, install the new unit to current code, connect all gas, water, and venting lines properly, and test for leaks and full functionality before we pack up. We also haul away your old water heater at no extra charge. You're left with reliable hot water, a clean workspace, and our workmanship warranty backing the install.

Frequently Asked Questions
-
Replacement costs vary based on the tank size, brand, any code upgrades needed, and your home's existing setup. After a free in-home assessment, we provide a flat-rate estimate with no surprises. South Pasadena's historic housing stock means venting, strapping, or expansion corrections come up more often here than elsewhere — if yours needs them, they're in the quote up front rather than added mid-job.
-
Most standard replacements take 2–3 hours from start to finish, including removal, installation, connections, and full system testing. The tight service porch and basement installs common in South Pasadena can add an hour — we'll flag that at the estimate rather than at the invoice. If your heater is leaking right now, call us and we'll tell you honestly what today's schedule looks like.
-
Tank sizing depends on the number of people in your home, your peak hot water usage, and your existing setup. Most South Pasadena bungalows run 40- or 50-gallon units, but the original location often limits what will physically fit — a basement or service porch install can rule out a larger tank entirely. That's one of the reasons we assess in person rather than quoting over the phone.
-
Shut off the water supply valve on top of the tank, turn the gas control to "off," and call us at (323) 591-5773. In older South Pasadena homes the heater is often in a basement or service porch where a leak spreads before anyone notices. We're just north in Pasadena and carry the common sizes, so same-day replacement is usually realistic.
South Pasadena's housing stock is largely protected historic — Craftsman bungalows and Spanish-style homes where the plumbing has been added onto rather than replaced. That means a water heater swap here regularly turns up venting clearances, strapping, and expansion control that were fine in 1948 and aren't now. We check all of it before we quote, so the number doesn't move after we've started.

Whole Home Water Filtration Systems
Foothill groundwater runs hard, and how hard depends on which company serves your street. We test what's actually coming out of your tap, then install softeners, salt-free conditioners, whole-home carbon filtration, and under-sink RO.
Gas Lines & Gas Leak Detection
Red tag from SoCalGas, or you smell gas near the meter? We locate the leak, pressure-test the system, and repair or replace what's failing — plus new gas runs for tankless units, ranges, dryers, and fire pits.
Older South Pasadena homes often can't take a modern high-BTU tankless unit without a gas line upgrade and a new vent path. We check capacity before we quote, not after. Navien, Rinnai, Noritz, and Rheem.
