The repair readings, priced apart by frame
| Repair reading | Frame A reading | Frame B reading |
|---|---|---|
| Anode rod | $25-$80 part alone, parts-only | $150-$350 installed |
| Average repair | no average printed | $150-$700 installed |
| Tank flush | $210 service row | $75-$250 flush and clean |
Each reading is one frame's own counting of one repair case: a parts-only row counts the part alone, an installed row counts the fitted service, and the two rows are never blended.
The repair rows, priced apart
| Repair row | Frame A reading | Frame B reading |
|---|---|---|
| Thermostat / heating element | $20-$415 / $15-$60 parts-only | $100-$350 / $100-$350 installed |
| Gas valve / thermocouple | $75-$210 part / no part line | $150-$550 / $100-$325 installed |
| Pressure relief valve | $20-$210 service row | $50-$300 installed |
| Anode rod / dip tube | $25-$80 / $25 parts-only | $150-$350 / $100-$300 installed |
| Flush row | $210 service row | $75-$250 installed |
Frame A prints its installed service rows apart -- pressure relief valve replacement at $20 to $210, dip tube replacement at $25 to $155, anode rod service at $20 to $210, and expansion tank replacement at $105 to $415, never blended into its parts-only lines.
The anode rod row, priced apart by frame
| Anode rod row, as published | Frame | 2026 reading |
|---|---|---|
| Anode rod, the part alone | Frame A, parts-only | $25-$80 |
| Anode rod replacement, installed | Frame B | $150-$350 |
The anode rod row counts differently in each frame and the readings stand apart. The two frames price the same anode rod job differently -- Frame A reads the anode rod part alone at $25-$80 in its parts-only frame, while Frame B reads an anode rod replacement installed at $150-$350. That difference is named as a frame difference on every page here, never averaged, and no parts-only figure is ever presented as an installed price.
The totals behind the rows, and the neighbours named apart
Behind the rows stand the headline lines: Frame A thermostat part at $20 to $415 and gas burner part at $180, Frame B average repair at $150 to $700 and leak repairs at $100 to $1,000. The repair ticket against the replacement ticket prices apart on the repair-vs-replacement guide. Named apart, never a row here: the replacement hubs' installed replacement heater, their own hubs' field; the tank-leak line standing as the named boundary on every page (a leaking tank is a replacement, never a repair row); and tankless descaling maintenance as a standalone service, its own hub's field, a maintenance visit and never a repair row.

Frequently asked questions
What does water heater repair cost by part, as reported?
Frame A is parts-only: anode rod part at $25 to $80, heating element part at $15 to $60, thermostat part at $20 to $415. Frame B prints installed figures: average repair at $150 to $700, anode rod replacement at $150 to $350, and thermocouple replacement at $100 to $325. A frame difference, never averaged.
What does the anode rod row print at, as reported?
Frame A prints the anode rod part alone at $25 to $80 in its parts-only frame. Frame B prints anode rod replacement installed at $150 to $350, and Frame A prints an anode rod service row at $20 to $210 standing apart from its parts-only table.
What do the gas valve and thermocouple rows print at, as reported?
Frame A prints a gas valve part at $75 to $210 parts-only and a gas burner part at $180. Frame B prints gas control valve replacement at $150 to $550 and thermocouple replacement at $100 to $325 installed.
What do the dip tube and flush rows print at, as reported?
Frame A prints a dip tube part at $25 parts-only, a dip tube replacement service row at $25 to $155, and a tank flush at $210. Frame B prints dip tube replacement at $100 to $300 and flush and clean at $75 to $250 installed.
Is a repair-line row the same purchase as an installed replacement heater or a tankless descaling visit?
No. Each row prices one failed part in one repair visit as its own ticket, off $150 to $700 for an average repair in Frame B and parts-only lines in Frame A. The hub installed tier, the tank-leak boundary, and tankless descaling maintenance sit in their own lanes, named apart here.
