Water Heater Replacement in Altadena
Altadena's older foothill homes come with older plumbing — original galvanized lines, water heaters tucked into garages and back closets, and gas systems that predate current code. Premier Flow Plumbing is based minutes away in Pasadena, so when a water heater fails in Altadena we can usually be out the same day, shut the leak down, and have hot water back before the end of the afternoon. We install the new unit properly, connect gas, water, and venting, test everything, and haul the old tank away before we leave. Thinking about going tankless instead? We install Navien, Rinnai, Noritz, and Rheem tankless systems as well, and we'll walk you through both options honestly at your free in-home estimate.
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. Most straightforward replacements fall into a predictable range — we'll give you a clear number before any work begins. Altadena's older foothill homes occasionally need venting or connection corrections, and if yours does, that's in the quote up front rather than added later.
-
Most standard replacements take 2–3 hours from start to finish. That includes removing the old unit, installing the new tank, connecting all lines, and full system testing. We're based minutes away in Pasadena and stock the common sizes, so if your heater is leaking right now, an Altadena call is usually a same-day appointment rather than a next-week one.
-
Tank sizing depends on the number of people in your home, your peak hot water usage, and your existing setup. During our free in-home estimate, we'll assess your needs and recommend the right size. Most Altadena homes run 40- or 50-gallon units, though older foothill houses with added bathrooms often need more capacity than what's currently installed.
-
Shut off the water supply valve on top of the tank, turn the gas control to "off," and call us at (323) 591-5773. A leaking tank does not repair itself and usually gets worse fast. We're based in Pasadena, minutes from most Altadena addresses, and we carry the common sizes on the truck — in most cases we can be out the same day, get the old unit out, and have hot water back before evening.
Full-Service Plumbing in Altadena
Altadena is unincorporated LA County, and the plumbing here doesn't follow one set of rules. West Altadena is on Lincoln Avenue Water Company, central and east on Rubio Cañon, southeast on Las Flores — so pressure and water chemistry change block by block. We price the house in front of us, not a template.
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.
Whole Home Water Filtration Systems
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.
Gas Lines & Gas Leak Detection
Going tankless in an older Altadena home usually means upsizing the gas line and running a new vent — not just hanging a box on the wall. We size the gas first and quote the real scope. Navien, Rinnai, Noritz, and Rheem.
