Water Heater Temperature And Pressure Relief Valve, Male x Female

Critical Protection for Water Heaters – Cash Acme NCLX T&P Relief Valve

The Cash Acme NCLX Combination Temperature and Pressure Relief Valve is engineered to protect water heaters and hot water storage tanks from excessive pressure and temperature conditions. Built to meet ASME and CSA performance requirements, this valve is ideal for residential and light commercial systems where safety and code compliance are non-negotiable.

Its combination design offers dual protection in one compact unit, and the automatic reseating mechanism ensures continued performance after discharge events—no manual reset needed. Backed by rigorous testing and high-grade materials, the NCLX is a proven solution for long-term system reliability.

Installation Considerations

This valve is factory preset and sealed. Installation should follow local plumbing code requirements and manufacturer guidelines. A discharge pipe must be properly routed to an approved drain and terminate no more than 6 inches from the floor. It is strongly recommended that this valve be installed by a licensed professional.

Contractor-Focused Performance

The NCLX is a go-to choice on job sites thanks to its reliability, code compliance, and ease of integration with tank-style water heaters. With each valve factory-tested prior to shipment, installers can trust consistent performance out of the box. The automatic reseating function reduces callbacks, while the inert coating prevents fouling in high-mineral-content systems.

Summary

For critical over-temperature and over-pressure protection, the Cash Acme NCLX is a smart, code-approved solution for residential and light commercial water heater systems. Built to perform and tested to last, this valve delivers the safety and reliability that professionals demand.
