: Standard 3/4-inch NPT water inlet and outlet. Gas Connection : 1/2-inch NPT gas connection.
The 5V40-7 is an economy unit. It is not the most efficient or durable, but it is one of the most affordable 40-gallon natural gas tanks on the market (typically $450–$550 at Menards).
If the pilot flame refuses to stay lit, it is typically caused by a degrading . The thermocouple must sit directly in the flame and generate roughly 25 to 30 millivolts to signal the main gas control valve to remain open. If the voltage drops below this threshold, the gas valve shuts down as a safety precaution. Insufficient Hot Water
The 5V40-7 uses a single anode rod integrated into the hot water outlet nipple.

| Specification | Detail | |---------------|--------| | | 5V40-7 | | Tank Capacity | 40 Gallons | | Energy Source | Natural Gas | | BTU Input | 38,000 BTU/hour | | Recovery Rate | 33.9 Gallons per hour (90°F rise) | | First Hour Rating | 70 Gallons | | Energy Factor | 0.60 | | Warranty | 6-Year Tank & Parts (Limited) | | Venting Type | Atmospheric / Natural Draft |
Standard 40-gallon atmospheric gas heaters of this specific generation usually feature an input of roughly 36,000 to 40,000 BTU/h .
40,000 BTUs on a 40-gallon tank gives a solid recovery rate — about 41 GPH at a 90°F rise. That means after a shower, it replenishes hot water relatively quickly (around 20-25 minutes to reheat the whole tank).
Usually features top water connections with a standard 3/4" size. : Standard 3/4-inch NPT water inlet and outlet
Employs a standard 1/2-inch gas control valve inlet (Robertshaw or Honeywell thermostatic gas valve assembly). Maintenance and Lifespan Expectations
The Richmond 5V40-7 water heater comes with several features that make it an attractive option for homeowners:
The interior of the steel tank features a fused porcelain ceramic lining designed to resist aggressive water chemistry and prevent internal rust.
: Propane models like the 5V40-7 recover hot water approximately 2.5 times faster than standard electric units. It is not the most efficient or durable,
: Glass-lined or porcelain-lined tank to prevent corrosion and extend service life.
Suitable for homes with 2-4 people, providing hot water for showers, dishwashers, laundry, and sinks.
: Provides roughly 64 gallons of hot water in the first hour of use.
