What We Fix After Other Contractors
Replacement quoted for a $285 repair
General plumbers misread Navien E003 and Rinnai Code 12 as unit failure. In OC’s 15–19 GPG hard water these are calcium scale blocking the heat exchanger — a professional descaling resolves them same day. “Three plumbers couldn’t fix it. The specialist solved it in minutes” is a real quote from OC competitor reviews.
Code violations left uncorrected
Improper venting. Wrong gas line size. No earthquake strapping. No permit. We see this in Old Town Tustin craftsmans, pre-2000 Tustin Ranch builds, Columbus Square shared-wall venting. We bring everything to code, document every correction with photos, and pull the permit for any work requiring inspection.
Wrong unit size for the home
A 7.5 GPM unit installed in a 4-bath Tustin Ranch home needing 9–11 GPM delivers lukewarm water during simultaneous use and wears faster. We size using actual peak demand calculation — not guesswork. Navien NPE-240A2 or Rinnai RU199iN for most large Tustin Ranch homes.
Gas line not upgraded
Pre-1995 Tustin homes have ½-inch gas supply lines that cannot sustain full tankless load. A contractor who skipped the gas line assessment left a unit that throws ignition errors under demand. We measure the gas line at every assessment — always in the written quote upfront.
No maintenance plan set up
The original contractor installed the unit and disappeared. No 12-month descaling reminder. No hard water guidance. By year 3 in Tustin’s 15 GPG water the unit is throwing error codes. We take over maintenance, perform a full service visit, and set the annual reminder going forward.
Warranty voided — permit never pulled
California requires a permit for every water heater installation. Skip it and you void the manufacturer warranty, create an insurance liability, and a resale disclosure problem. We remediate unpermitted installations by bringing work to current code and obtaining required permits where legally possible.
★★★★★
“Navien E003 at 6:45am Tuesday. Called at 7am, they were here by 10am. Eight years of Tustin hard water with no maintenance — heat exchanger blocked with scale. They showed me what it looked like before cleaning it. Fixed by noon for $285. I had been quoted $1,800 for a replacement the day before.”

Rescue FAQs
My tankless was installed by another company and keeps failing. Can you take over?
Yes. We assess existing installations, identify code violations, maintenance neglect, or sizing errors, and provide a transparent written correction quote.
Another plumber quoted full replacement. Should I get a second opinion?
Always. Codes like Navien E003 and Rinnai Code 12 are frequently misdiagnosed as catastrophic failures when they are simply scale blockages correctable via descaling.
Can you fix an installation with code violations?
Yes. We bring substandard work up to current Tustin and OC building codes, document everything, and pull required permits.
