Conbraco 18C-402-30 Valve
The Conbraco 18C-402-30 is a heavy-duty temperature and pressure relief valve designed for residential and commercial water heater applications. This T&P valve features a 3/4" Male NPT inlet and a 3/4" Female NPT outlet, providing a direct interface with standard tank connections. Engineered for high-demand systems, it is factory set at 150 PSI and 210°F, with a certified 95,000 BTU capacity. The 3-inch probe is constructed with a high-temperature resistant coating to prevent mineral scaling and ensure accurate thermal response in the upper water column. Built with a corrosion-resistant bronze body and stainless steel springs, this Apollo 18C series valve provides critical over-pressure protection and thermal expansion relief. For contractors performing water heater maintenance, this lead-free valve meets essential safety codes and ensures reliable seat reset after activation, minimizing nuisance leaking in high-pressure plumbing systems.
- Corrosion-Resistant Bronze Body: Ensures long-term structural integrity in harsh water conditions.
- 95,000 BTU Rating: Suitable for a wide range of standard and high-recovery water heaters.
- Anti-Scale Element Coating: The 3-inch probe is designed to resist calcification for precise temperature sensing.
- ASME and ANSI Compliant: Meets rigorous industry standards for safety and pressure relief performance.
Common Questions
Is the probe length sufficient for thick-walled tanks?
The 3-inch probe is the standard length for most residential and light commercial water heaters, ensuring the sensing element reaches the hottest water in the top of the tank.
Can this valve be installed horizontally?
While T&P valves should ideally be installed vertically in the designated tank port, always follow local plumbing codes regarding the orientation and discharge piping to ensure proper drainage.
What causes a T&P valve to weep or drip?
Dripping is usually caused by thermal expansion in a closed system or debris trapped on the valve seat. If the system pressure exceeds 150 PSI, the valve is performing its intended safety function.
