A Reliance 606 water heater may cost about $500-$900 for the tank when available, while a professionally installed replacement commonly totals $1,100-$2,200. The final price depends on tank capacity, fuel type, local labor, removal needs, and whether connections or code items need updating.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Tank only | $500 | $700 | $900 | Comparable residential tank; model availability varies |
| Installed replacement | $1,100 | $1,600 | $2,200 | Standard swap with typical access |
| Removal and disposal | $50 | $125 | $250 | May be included in the installation quote |
| Labor | $400 | $650 | $1,000 | Higher for difficult access or connection changes |
Assumptions: U.S. pricing for a standard residential tank replacement; taxes and unusual code upgrades may be extra.
What a Reliance 606 replacement usually costs
For budgeting, expect roughly $1,100-$2,200 for a like-for-like installed replacement. A straightforward swap in a garage or utility room may land near $1,300-$1,700; tight access, new piping, or electrical work can raise the total. Tank-only pricing is less predictable because older or discontinued models may not be stocked by local retailers.
“606” alone may not identify the heater’s capacity, fuel, or full model configuration. Before requesting quotes, check the rating plate for the complete model number, gallon capacity, energy source, and input rating. Use the full rating-plate details to compare replacement equipment rather than relying on “606” by itself.
Tank, labor, and connection charges on the quote
A useful estimate separates the equipment from the work. Electric and gas models have different connection and venting needs, so a quote for a different fuel type is not directly comparable. The table gives typical ranges for a standard residential replacement.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Water heater | $500 | $700 | $900 | Standard tank, comparable capacity |
| Labor | $400 | $650 | $1,000 | Disconnect, install, test; often 3-6 hours |
| Materials and fittings | $50 | $150 | $350 | Connectors, shutoff, pan, or piping |
| Permit and inspection | $0 | $75 | $250 | Depends on local requirements |
| Haul-away | $50 | $125 | $250 | Removal and disposal of the old tank |
A common labor calculation is 3-6 hours at roughly $100-$165 per hour, though contractors may quote a flat installation fee. Ask whether the quote includes startup testing, disposal, fittings, and required permits.
How tank size and fuel type change the price
Capacity is a major comparison point: many households use 40- or 50-gallon tanks, but the right size depends on demand and the existing installation. A larger tank can add about $100-$300 to equipment cost. Gas units may require venting and combustion-air checks; electric units may need circuit or wiring work if the replacement’s requirements differ.
Changes from a tank to a tankless system, or from gas to electric, are not simple equipment swaps. New venting, electrical capacity, gas piping, or condensate drainage can add several hundred dollars or more. Match capacity and fuel first, then price optional efficiency upgrades separately.
How long installation takes and what labor covers
A standard replacement generally takes 3-6 hours for one or two technicians when the new tank fits the existing location and connections. Labor can exceed $1,000 when stairs, narrow closets, long pipe runs, or corroded shutoffs complicate the work. A same-day emergency appointment may also carry a premium of about $100-$300.
Ask the contractor to identify what is included in the labor charge: draining and disconnecting the old heater, setting and connecting the new tank, filling it, checking for leaks, and confirming operation. Clarify the labor scope before comparing flat-rate installation quotes.
When disposal, code work, or access adds expense
Haul-away may be included, but separate removal fees often run $50-$250. A drain pan, expansion tank, seismic straps, new shutoff valve, or updated vent connector can add roughly $50-$400 each, depending on the item and local labor. These upgrades are not automatically needed in every home.
Permit charges vary by city and may be zero in some areas or around $75-$250 where a permit and inspection apply. Difficult access can add $100-$500 or more if the crew must remove doors, carry the tank through tight stairs, or make substantial piping changes. Request written approval before any extra work begins.
Regional labor rates can shift the installed price
Labor and permit costs commonly make installed prices about 10%-25% higher in high-cost metro areas than in lower-cost rural markets. Dense cities may add parking, delivery, or access charges, while remote locations can face travel fees or limited contractor availability. These differences affect the total more than the brand name alone.
For a standard replacement, a lower-cost market might produce a quote near $1,100-$1,500; a typical suburban market may fall around $1,300-$1,900; and a high-cost metro installation can reach $1,700-$2,500. Use local written bids rather than a national average as the final budget.
Repairing the 606 versus replacing the tank
A service call and diagnosis often cost $75-$200, before parts or repair labor. Common repairs such as replacing a heating element, thermostat, or gas control can total roughly $150-$500, depending on part availability. A leak from the tank body generally cannot be repaired reliably, making replacement the practical comparison.
If a repair approaches half the cost of a new installed heater, compare the tank’s age, condition, and warranty before authorizing work. Older models may have limited parts availability, and a replacement could improve reliability even if its upfront price is higher. Get a repair diagnosis before assuming the entire heater needs replacement.
Lowering the replacement bill without cutting essentials
Keep the same fuel type and similar capacity when the household’s hot-water needs have not changed. Schedule a non-emergency replacement when possible, clear the route to the heater, and ask whether the contractor’s disposal fee is already included. Compare at least two itemized quotes that specify model, capacity, warranty, labor, permits, and extra-work rates.
A basic replacement may be cheaper than adding premium controls or an oversized tank that the household does not need. However, required safety or code work should not be removed simply to lower the bid. Control optional upgrades while keeping necessary installation and safety work in the quote.
