Watts 9DM3-S Forged Brass Dual Check Backflow Preventer with Intermediate Atmospheric Vent, 1/2", Female Union

• It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply
• It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves
• For continuous pressure, non-health hazard applications in smaller supply lines
• It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
• A secondary check valve utilizes a rubber disc-to-metal seating
• In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
• True line-sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
• Maximum flow at low pressure drop
• Furnished with union connections to facilitate removal and replacement for maintenance
• Compact for economy combined with performance
• Design simplicity for easy maintenance
• Can be installed vertically or horizontally

Cash Acme VR-801 VAC uum relief valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems. It works by preventing internal VAC uum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury VAC uum. Atmosphere admitted to the system breaks the VAC uum, preventing collapse of the storage tank.,

Resideo Braukmann AM-1 series accurately adjusts, maintains and limits the hot water temperature to a desired setting selected by the user. By installing a Resideo Braukmann AM-1 mixing valve, raising water heater storage temperature setting and limiting mixed outlet water temperature to a safe temperature, more usable hot water is available.

• Features dual purpose mixing or diverting values
• Offers constant water temperature under changing operating conditions
• Temperature is limited at any point and if cold water supply is interrupted, flow reduction occurs in seconds
• Provides reliable performance at minimum flow of 5 gpm and proportional valve for simultaneous control of hot and cold
• Tamper-resistant design with nickel-plated brass construction and EPDM o-rings
• Designed for easy maintenance and Teflon coating prevents mineral build-up and extends life
• Teflon-coated shuttle, EPDM rubber o-ring
