Richmond Water Heater Age

Richmond is a Rheem-built brand, so the serial number uses Rheem's code. Skip the letters at the start; the next four digits are usually the month and year. Enter the serial below.

Serial number age lookup

Does the label print a manufacture date? Look for MFG DATE, MFD or DATE OF MFR. A printed date beats any decoder, so enter it if you have one.

Finding the label on a Richmond tank

Richmond labels follow Rheem’s layout: a white label on the side of the tank, above the gas valve on gas models or between the element covers on electric ones. The serial is on its own line, often with a bar code underneath. Richmond model numbers usually start with digits for the warranty term (such as 6, 9 or 12) followed by letters and size codes, which makes them easy to tell from the serial.

How the Richmond date code works

Richmond serials use the same layout as Rheem:

  • Leading letters (R, RC, RHNG and similar): skip them.
  • Next four digits: month and year. RC0915C12345 is September 2015.
  • Week-based variant: some serials put a two-digit week before the year instead. M311612345 is week 31 of 2016, which is early August.
Month (2 digits) + year (2 digits) + plant letter + 5 digits Rheem's own documented layout: 1209D01234 is December 2009.

A retail brand with a numbered warranty

Richmond is mostly sold through home-improvement retail, and its model numbers usually start with the tank warranty term: a leading 6, 9 or 12 generally points to a 6, 9 or 12-year tank warranty. That’s handy when you’re deciding whether a failing tank might still be covered.

The longer-warranty versions usually differ from the basic one in anode protection, insulation and sometimes element type rather than in the steel tank itself. So a 12-year Richmond in soft water may well outlast its warranty, while a 6-year model in very hard water may not reach it.

Electric tank10–15 years

Warranty check, step by step

  1. Decode the serial above to get the manufacture date.
  2. Find the warranty term from the model name or number (6, 9 or 12 years is common).
  3. If the tank leaks and is still inside the term, contact the retailer or the manufacturer with the model, serial and proof of purchase. Most tank warranties replace the tank but not the labor.

What to do with your result

Under the warranty term: don’t pay for a new tank until you’ve checked coverage.

Past the warranty but under 10 years: maintain and repair it. Elements, thermostats and thermocouples are inexpensive.

Over 10 years: plan a replacement, especially if the heater is indoors over a finished floor. If you’re replacing with the same brand, consider stepping up to a longer-warranty model if your water is hard.

About 8 to 12 years for a typical gas or electric tank, the same as other mainstream tanks. Hard water and no maintenance shorten that.

Simple parts such as electric elements, thermostats and drain valves are common DIY repairs if you're comfortable with electrical work. Gas controls, venting and anything involving the gas line should be done by a licensed pro.
