Repair or replace?
A quick honest rule of thumb from our techs:
- Under 8 years old + minor part failure → repair
- 10+ years old, rusty water, or leaking tank → replace
- Rising gas bills + slow recovery → check burner or replace
- Popping/rumbling sounds → sediment; flush or replace
FAQ
What size tank do I need?
1–2 people: 40 gal · 3–4 people: 50 gal · 5+ or big tubs: 75 gal. We’ll confirm on-site.
How long does a tank last?
8–12 years for most tanks. Annual flushes and anode inspection push that closer to 15.

Always — included in every install, along with permit, pan, and code-required upgrades.

No surprises, no upsells. Just a clean install, a properly permitted job, and a warranty that actually gets registered.
