The job priced by system type: hot-only, hot-and-cold, and filtration rows apart, frame by frame.

Orange County, CA · Updated 2026 · Costs shown as ranges — your quote will vary by installer and scope

Reading this guide: every figure below is a range from published 2026 pricing data — not a quote. Two frames are named apart and never blended: Frame A (the DIYorNot frame) and Frame B (the contractor and market frame). The frames count the same job differently, and that difference is named on every page. Always get 3 written quotes.

The type readings, priced apart by frame

System typeFrame A readingFrame B reading
Hot-only system, pro job$575$200-$600 band
Hot-only system, unit alone$325no unit-alone row by that name
Hot-and-cold system rowno separate row by that name$200-$600 band, higher-end models above it

Each reading is one frame counting of one system type in one job, never blended across types or frames.

The labor lines behind the type rows

Rows present in one frame and absent in the other are printed as absent, never filled from the other frame. The time rows stand in Frame A alone; the split installation bands stand in Frame B alone.

The totals count the whole job behind the type rows, and no page adds type rows into one blended total. The frames count the same job on different bases -- a priced pro-against-DIY comparison at $575 against $325 for the unit alone in Frame A, against contractor and market bands at $200-$600 for the unit and installation, $150-$400 for professional installation, and $350-$1,400 in total in Frame B. That difference is named as a frame difference on every page here, never averaged.

The neighbours named apart

Scope readings price apart on the companion guide. Named apart, never a row here: the kitchen-faucet installation ticket and its add-ons line, tankless water heater installation, hot water recirculation pump installation, whole-house water heating, and water filtration installation, each in its own lane.

Frame B prints the filtration-combination row inside its total at $350 to $1,400, beside professional installation at $150 to $400. Frame A prints no such row, and the row here is a dispenser type, never the water filtration installation lane.

What does the whole job print at behind the type rows, as reported?

Is a hot-only job the same purchase as a hot-and-cold job or a kitchen-faucet ticket?

No. Each row prices one system type in one job, off a $575 pro figure and a $325 unit-alone figure in Frame A. The kitchen-faucet ticket, tankless installation, recirculation pump installation, whole-house water heating, and water filtration installation sit in their own lanes, named apart.
