650 Delta Gas Valve Recall: Is Your Water Heater a Ticking Time Bomb?
A faulty gas valve is one of the most critical safety issues a homeowner can face. The device that controls the flow of natural gas or propane into your appliance is the single most important safety component.
When this part fails, it can lead to dangerous gas leaks, loss of heat, or even a fire. This guide breaks down the widespread issues concerning the 650 Delta gas control valve, often mistakenly called a “recall,” and provides a clear action plan to keep your home safe.

Is There an Official “650 Delta Gas Valve Recall”?
First, it is crucial to clarify what most people mean by the “650 Delta Gas Valve Recall.” There are two separate issues involving products with similar names, which often causes confusion. Understanding the difference is key to solving your problem.
The Real Issue: Widespread Failures in Residential Water Heaters
The problem that affects most homeowners involves the SIT 650 Delta gas control valve, commonly found on popular residential water heater brands like Rheem, Ruud, and Richmond. These units, particularly those manufactured between 2018 and 2021, have experienced a high rate of failure.
The most common symptom is the pilot light repeatedly going out. While this is not an official safety recall issued by the Consumer Product Safety Commission (CPSC), the problem is so prevalent that manufacturers are often aware of the defect and provide warranty replacements. The failure typically stems from a faulty internal component, not an external gas leak.
The Official CPSC Recall: Delta-Branded Gas Ball Valves
Separately, there is an official CPSC recall for “Delta Gas Ball Valves” manufactured by Masco Canada. These are distinctly different products. They are chrome, manually-operated ball valves primarily used in laboratories and commercial settings, not inside your home’s water heater.
These were recalled due to a defect that could cause small gas leaks when the valve is open. This article focuses on the first issue—the failing SIT 650 Delta valve in your water heater—as this is the problem plaguing countless homeowners.
How to Check if Your Water Heater Has the Faulty Valve
Identifying the problematic valve is a straightforward process. You do not need any special tools, just a flashlight and a few minutes. Taking these steps can confirm if your appliance is at risk.
Start by locating the gas control valve on your water heater. It is the box-like component near the bottom of the tank where the gas pipe connects, featuring a control knob for temperature settings (often blue or grey).
Look for a label on the valve itself. This label will contain the manufacturer’s name and the model number. If you see “SIT” or “Delta” along with the model number “650,” you likely have the component known for these widespread failures.
A Deeper Dive: The Technical Flaw
The core of the problem isn’t the entire valve but a tiny, crucial safety component within it: the thermal cutoff fuse, also known as an Emergency Cut Off (ECO). This fuse is designed to interrupt the electrical current from the thermocouple if temperatures get dangerously high, shutting off the gas.
In the defective batch of 650 Delta valves, this fuse fails prematurely under normal operating conditions. When it fails, it breaks the circuit, and the gas valve shuts off the pilot light, exactly as it would in a real emergency. This is why the pilot light will not stay lit, even with a brand-new thermocouple.
Symptoms and Solutions for the 650 Delta Valve Issue
Recognizing the signs of a failing 650 Delta gas valve is the first step toward a solution. The primary symptom is consistent and frustratingly repetitive. Homeowners find their pilot light is out and they have no hot water, forcing them to relight it daily or even multiple times a day.
| Affected Brands | Valve Model | Common Symptoms | Primary Solution |
|---|---|---|---|
| Rheem, Ruud, Richmond, Vanguard, GE | SIT 650 Delta (e.g., AP15255A-1, AP15255D) | Pilot light will not stay lit; requires frequent relighting. | Contact manufacturer for a warranty replacement valve (often a White-Rodgers model). |
| Various Gas Water Heaters | SIT 650 Delta | No hot water despite relighting the pilot. | Professional diagnosis and replacement by a qualified technician. |
| Models from 2018-2021 | SIT 650 Delta | Appliance functions for a few hours, then shuts off. | Do not attempt a DIY bypass; insist on a full valve replacement. |
Your Step-by-Step Action Plan for a Faulty Valve
If you have identified the SIT 650 Delta valve on your water heater and are experiencing pilot light issues, do not wait for the problem to resolve itself. Follow these steps to get your hot water running safely and reliably.
Step 1: Gather Your Information
Before contacting the manufacturer, locate the model and serial number of your water heater. This information is printed on a large label on the side of the tank. Having this ready will expedite the warranty process significantly.
Step 2: Contact the Water Heater Manufacturer
Call the customer service or technical support line for your water heater brand (e.g., Rheem, Ruud). Explain the issue clearly: the pilot light will not stay lit, and you have identified the SIT 650 Delta gas control valve.
Given how common this issue is, support representatives are often familiar with the problem. They will use your serial number to confirm the manufacturing date and determine if you are eligible for a free replacement valve under warranty.
Step 3: Schedule a Professional Installation
Under no circumstances should you attempt to replace a gas valve yourself unless you are a qualified professional. Working with gas lines is dangerous and requires specialized knowledge and tools to ensure a leak-free, safe installation.
Once the manufacturer sends the replacement part, contact a licensed plumber or HVAC technician to perform the installation. The manufacturer may even cover labor costs in some cases, so be sure to ask.
While you evaluate the health of your water system, it’s also a prudent time to consider the age of your unit. Many homeowners wonder if they should replace a 30-year-old water heater, and a critical part failure can be the perfect catalyst for an upgrade.
Beyond the Valve: A Proactive Approach to Home Safety
Resolving the gas valve issue is your immediate priority. However, you can use this opportunity to implement a broader safety and maintenance strategy for your entire home. A truly safe home is one where potential issues are anticipated and managed proactively.
Install Carbon Monoxide and Explosive Gas Detectors
Every home with gas appliances should have both carbon monoxide (CO) detectors and explosive gas detectors. A CO detector will not alert you to a natural gas or propane leak, and an explosive gas detector will not sense carbon monoxide.
Install them according to the manufacturer’s instructions, typically with CO detectors on every level and an explosive gas detector near your gas-burning appliances. This provides a critical layer of protection against silent threats.
Commit to a Whole-Home Safety Checklist
A holistic view of home maintenance prevents small issues from becoming large dangers. For instance, ensuring the correct garage door arm angle can prevent catastrophic door failure. Proper safety checks extend to every room.
Even aesthetic choices can have safety implications. When selecting a ceiling fan for an 8ft ceiling, ensuring proper clearance is not just about style; it’s about preventing injury. Apply this safety-first mindset throughout your home.
The Unseen Danger: Venting and Airflow
A gas appliance requires proper ventilation to operate safely. A blocked or improperly installed vent flue can cause dangerous carbon monoxide to build up inside your home, even if the gas valve is working perfectly.
During your annual appliance inspection, ask the technician to check the entire venting system for blockages, corrosion, or disconnections. This simple check is one of the most important things you can do for your family’s safety.
Frequently Asked Questions (FAQ)
Is the replacement gas valve free of charge?
In most cases, if your water heater is within the warranty period and has the known-to-be-faulty 650 Delta valve, the manufacturer will ship you a replacement part for free. However, labor costs for the installation may or may not be covered.
Can I use my water heater while I wait for the part?
It is strongly advised not to. A failing gas control valve is a serious safety concern. Continuously relighting an appliance with a faulty valve can create a dangerous situation. It is best to shut off the gas supply to the water heater and wait for the professional repair.
