Tank is intended for installation in any pumped water system controlled by a pressure switch and can serve as a storage vessel as well as a pulsation dampener. By smoothing water flow and reducing on/off switch cycling of the pump the result is quieter operation and longer pump life. The even flow of water gives better control of hot water temperature with systems using instant water heaters. Easily fitted to new or existing systems with quick connect fittings. Mounting point for optional pressure switch. Internal bladder. Manufactured from food grade materials, NSF Standard 18 listed.
