  • Excellent job, respectful team

    Flash Plumbing Inc did an excellent job! They swapped out the 40-gallon tank for a new tankless heater. The entire time, they were professional, courteous, and respectful. They left the area cleaner than when they started.

  • Daniel & crew are great

    Daniel and crew were great, taking the time to get my 50-gal water heater installed right and now looks great with working shut off values!

  • The only plumber we will call

    A fair price and a really easy company to work with. I’ve lived in my house for 10 years and have used 3 plumbers. This is the only plumbing company I will work with again.

  • Fixed leak same day

    Flash Plumbing Inc took my job on the same day! I had a leaking toilet upstairs that threatened to damage the ceiling downstairs. The guys arrived and fixed the issue! Will definitely use them in the future.

  • Honest assessment & quality work

    I’ve used Flash twice: once for a major operation to replace some shower pipes and once for a simple kitchen sink clog. In both cases, they were great! Responsive, same day service, and honest assessment of my options. Fast and high quality work.

FAQ

Water Heater Replacement questions.

Still have a question? Call (626) 360-8993

How long does a water heater replacement take?

A like-for-like tank replacement usually takes a few hours. Switching to tankless takes longer because of gas, venting and electrical work.

Can you replace my water heater the same day?

Often, yes. Call us early and we'll let you know whether same-day replacement is possible for your unit.

Should I replace my tank with a tankless heater?

If your tank has failed anyway, it's a good time to consider tankless. It costs more upfront but gives endless hot water and frees up space.

What happens to my old water heater?

We drain it, disconnect it and haul it away for proper disposal as part of the job.
