Water Heater Repair Services in Roseville

Most water heater problems can be fixed in a single visit. Here’s what we repair every week in Roseville homes:

No Hot Water or Not Enough Hot Water

A failed heating element, thermocouple, gas valve or sediment-choked tank can leave you with cold showers. We find the cause and fix it fast.

Leaking Water Heater Repair

Leaks from fittings, valves or supply lines are usually repairable. A leak from the tank itself means replacement — we’ll tell you which you have.

Pilot Light, Burner & Thermostat Problems

Pilot won’t stay lit? Water too hot or too cold? We repair igniters, thermocouples, burners and thermostats on gas and electric units.

Water Heater Flushing & Maintenance

Rumbling or popping noises usually mean sediment buildup. Our maintenance service flushes the tank (or descales a tankless unit), checks for leaks and tests safety parts so your water heater lasts for years.

Rusty or Smelly Water

Discolored or rotten-egg-smelling hot water often points to a worn anode rod. Replacing it protects your tank from corrosion.

Valve & Pressure Relief Repairs

A dripping temperature and pressure (T&P) relief valve is a safety issue. We test and replace T&P valves, drain valves and shut-offs.

Same-Day & Emergency Water Heater Repair

A burst tank or major leak can flood your garage in minutes. We keep openings for urgent water heater calls Monday through Saturday, 8 a.m. to 5 p.m., and reach most Roseville homes the same day. While you wait, shut off the cold water supply at the top of the tank and turn off the gas or breaker.

Should You Repair or Replace Your Water Heater?

We’ll always give you the honest answer — even when a repair is the cheaper option. As a rule of thumb, replacement makes more sense when:

Your tank water heater is 10+ years old (tankless: 20+ years)
The tank itself is leaking or rusted
Repair costs exceed about half the price of a new unit
You're running out of hot water as your household grows
Your energy bills keep climbing

If your unit is younger and the tank is sound, a repair is usually the smart move.

Water Heater Replacement & Installation in Roseville

When your water heater is beyond repair, Mach 1 Plumbing handles water heater replacement in Roseville from start to finish. We assess your hot water needs, recommend the most energy-efficient and cost-effective tank or tankless model, install it to code, and haul away the old unit.

Same-day replacement

We carry common 40- and 50-gallon gas and electric models, so most standard replacements are done the day you call.

Permits and code compliance

Water heater installation in California must meet state plumbing code, including earthquake strapping. We pull permits where the City of Roseville requires them, so your installation passes inspection and protects your warranty and home insurance.

Our installation process

Size your home’s hot water needs and recommend options with upfront pricing
Shut off and drain the old unit, then remove it
Install the new water heater, properly connected to gas or electric and fully plumbed
Add seismic strapping and expansion tank where required
Test for leaks, proper venting and temperature

 Trustindex verifies that the original source of the review is Google. We've worked twice now with Michael at Mach 1 Plumbing and both experiences were great. The first was for a clogged kitchen drain line and the second was for their outdoor leak detection service. Very professional, patient, explanatory, thorough and reasonably priced.  We'll definitely be calling Michael for any future plumbing needs!

 Trustindex verifies that the original source of the review is Google. Had a same day toilet & shower issue I couldn’t resolve on my own efforts (nothing was going down in either bathroom). They were at my home within a couple hours of calling, very professional and explanatory and resolved the issue at hand quickly. Turns out I’ve got a much bigger problem waiting for me, and I will not hesitate to get back in touch with Mach 1 about it. Thanks for the help!

Also, thank you to Mike the supervisor for sending someone ASAP to my home. I appreciate your professionalism and I recommend this company to anyone who needs plumbing. A+ plus.

 Trustindex verifies that the original source of the review is Google. When we arrived at our office early Monday morning, we were shocked to find our water main and backflow system completely stolen. We called Mach 1 Plumbing at 6:30 AM, and Michael was onsite within the hour. He handled everything with unbelievable urgency, professionalism, and skill — restoring our water service the same morning and leaving the jobsite spotless.

Then, unbelievably, the thieves came back the very next day, cutting through new barriers to steal the replacement setup. Once again, Mach 1 Plumbing responded immediately, worked efficiently, and had us back up and running in record time.

This company defines reliability, responsiveness, and true customer care. In an emergency situation, you couldn’t ask for better service or better people. We are beyond grateful for Michael and the Mach 1 team — professional, trustworthy, fast, and genuinely invested in their customers.

If you ever need emergency plumbing service, backflow repair, or water main replacement, Mach 1 Plumbing should be your first and only call. Thank you for turning two chaotic mornings into proof that outstanding service still exists! 💧🔧👏
