It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves. Series 9D is designed for continuous pressure, non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. Minimum Working Pressure: 25psi (172kPa), Maximum Working Pressure: 175psi (12.06 bar).

"Do not use this item for any installation or repair of potable water applications. This product does not comply with the "Safe Drinking Water Act," which requires that products meet low-lead standards in order to be used in systems providing water for human consumption (drinking or cooking). This item is for non-potable (non-human consumption) water applications only."

              I used it on my house boiler the old one was leaking. I'll clean the old one test after cleaning and if it doesn't leak I'll keep it as a back-up. I would suggest yearly maintenance (summer time) when tour boiler not used.

                                Ordered this check valve to replace one that was 19 years old and started to leak. I had ordered from PEX previously and was very satisfied with the order, pricing and fast shipping.

                                      At least this product works. Make sure you buy the Series 9D valve and don't go for the exactly-spec'd and lower costing BBFP backflow preventer as an alternative. Although the manufacturer of the BBFP is claimed to be Watts it is actually supplied by a subsidiary of Watts which makes me ask the question "What's the difference?". The BBFP failed on installation and despite multiple disassemblings and cleanings it kept failing.
