Recovery Rate & First-Hour Rating With a 38,000 BTU burner, the Richmond 5V40-7 can raise 38.8 gallons of water by 90°F per hour. The First Hour Rating (67 gallons) means you can take approximately two back-to-back showers (using 15-20 gallons each) plus run a dishwasher before the tank runs cold—adequate for most small to medium families. Energy Efficiency This is not a high-efficiency condensing unit. Its UEF of 0.62 places it near the minimum standard allowed by federal regulations for a 40-gallon gas water heater (the current minimum is 0.60 UEF). It lacks foam insulation (uses fiberglass blanket-type insulation). Consequently, expect annual operating costs around $280-$340 (depending on local gas prices), which is higher than a comparable 0.90 UEF condensing model. Lifespan & Durability
Vitraglas lining – Resists corrosion but is not as robust as premium brands’ proprietary coatings (e.g., Rheem’s Marathon). Anode rod – Replace every 3-5 years to maximize lifespan. Without replacement, tank failure occurs around 6-9 years. Estimated lifespan – 8 to 12 years with proper maintenance.
Installation Requirements (Must-Know Before Buying) Before purchasing a Richmond 5V40-7, verify the following: Clearance Space
Top clearance: 12 inches minimum to combustibles (e.g., wood, drywall). Sides: 6 inches clearance (0 inches if using Type B vent with protectors). Front: 18-24 inches for service access. richmond 5v40-7 water heater specs
Venting Compatibility You cannot use PVC or CPVC for venting. The 5V40-7 requires a metal vent (galvanized or stainless steel). If your existing water heater uses power venting (fan-assisted), this model is not a direct replacement —you would need to redo the vent system. Gas Supply The unit requires 5.0" – 10.5" W.C. gas pressure. A undersized gas line (e.g., 1/2" over 50+ feet) will cause poor performance. For runs over 20 feet from the gas meter, consider a 3/4" supply line. Water Quality If your home has hard water (above 7 grains per gallon), you must install an expansion tank and consider a water softener. Sediment buildup will destroy the bottom of the tank within 3-4 years. Common Problems & Troubleshooting | Symptom | Likely Cause | Fix | |---------|--------------|-----| | No hot water | Pilot light out | Relight pilot; replace thermocouple | | Rumbling/popping | Sediment buildup | Flush tank annually | | Water leaking from base | Tank corrosion or loose drain valve | Replace water heater (unrepairable if tank failed) | | Burner won’t stay lit | Bad thermocouple or gas valve | Replace thermocouple ($15 part) | | Low hot water volume | Dip tube cracked | Replace dip tube (3/4" brass adapter) | Warranty Details
Tank warranty: 6 years (limited) – non-prorated Parts warranty: 6 years (limited) – burner, gas valve, controls Labor coverage: Not included (standard for residential units)
Note: To validate warranty, registration must be completed within 90 days of installation. Keep proof of purchase and installation receipt.

A: No. The gas valve and pilot operate without any electrical connection. This makes it ideal for use during power outages. Q: What is the difference between 5V40-7 and 5V40-6? A: The “-7” revision often includes an updated gas control valve (electronic ignition in some cases) or a revised draft hood. Check the manual. Most parts are interchangeable. Q: Where is the serial number located? A: On the rating plate, located near the gas control valve or on the side jacket. Serial number decodes to manufacture date (e.g., 1925 = 25th week of 2019). Q: Can I install this in a mobile home? A: No. This unit is not certified for mobile/manufactured home use. Look for “MH” designation in model number. Final Thoughts The Richmond 5V40-7 is a straightforward, no-frills natural gas water heater. Its specs—40 gallons, 38k BTU, 0.62 UEF, and 58-inch height—make it a common choice for replacing older tanks in homes with traditional venting. While it lacks energy-saving features like electronic ignition or extra insulation, its low upfront cost and simplicity are its main selling points. Before purchasing, confirm your vent size (3-inch required), gas pressure, and clearance space. If your home has higher hot water demand (more than 3 people), consider moving up to a 50-gallon model like the Richmond 6V50-7. But for a budget-friendly, direct replacement of a failing 40-gallon natural gas tank, the 5V40-7 gets the job done.

The Richmond 5V40-7 is a legacy residential gas water heater. Manufactured under the Richmond brand (a subsidiary of the industry giant Rheem ), this unit was highly popular in the 1990s and early 2000s. It was frequently sold through hardware retailers and regional propane dealers. 📋 Core Specifications Because this model has been out of production for some time, the exact factory data sheets are archived. However, the alphanumeric model number breaks down its primary design traits: Nominal Capacity: 40 Gallons (Ideal for households with 2 to 4 people). Fuel Type: Typically configured for Propane (LP) Gas or Natural Gas (the "P" suffix usually denoted propane models). Venting Type: Traditional Atmospheric Venting (requires a standard chimney or B-vent to draft exhaust naturally). Burner Input: Standard 40-gallon atmospheric gas heaters of this specific generation usually feature an input of roughly 36,000 to 40,000 BTU/h . Tank Lining: Porcelain glass-lined steel to protect the internal tank from aggressive hard water and corrosive elements. Ignition System: Traditional standing pilot with a piezo igniter or manual match-lit pilot setup. ⭐ Key Features & Engineering Despite its age, the 5V40-7 boasted several durable design choices that were considered high quality for its era: EverKleen™ Self-Cleaning System: Many high-spec Richmond models of this era utilized a specialized dip tube that swirled incoming cold water. This action aggressively fought sediment and lime build-up at the bottom of the tank, prolonging the life of the unit and maintaining heat transfer efficiency. Rigid Foam Insulation: To combat standby heat loss, the tank was wrapped in a thick, dense layer of rigid foam. This prevented heat from radiating out of the tank when the burners weren't firing. Fast Recovery Rate: Propane models boasted a fast recovery time compared to their electric counterparts of the same era, allowing a quick turnaround of hot water during peak usage hours. Standard Safety Relief: Equipped with a standard side-mounted or top-mounted Temperature and Pressure (T&P) Relief Valve to prevent excessive pressure from building inside the tank. 🛠 Common Troubleshooting & Maintenance If you are currently running a Richmond 5V40-7, you are operating an older system. Review these common issues and structural maintenance practices: Pilot Light Outages: This is the most frequent call for this unit. If the unit fails to heat, the pilot light has likely blown out. If it refuses to stay lit after manual lighting, the thermocouple is likely worn out or covered in carbon and needs a replacement. Sediment "Popping" Noises: If you hear knocking or popping sounds when the burner fires, it is a sign of scale and sediment resting on the floor of the tank. Hooking a hose to the bottom brass drain valve and flushing the unit is heavily recommended. Anode Rod Checks: To prevent the tank from rusting through, check the sacrificial anode rod at the top of the tank. If it has completely dissolved, replace it immediately to extend the life of the metal tank. ⚠️ Important Considerations Richmond 5v40-7 Water Heater Q&A: Troubleshooting & Manual
