              This product is a direct OEM replacement! Fits perfectly, and the leaks have stopped! Well, for now, I still need to get a Pressure Reducing Valve (PRV) installed, but I am very satisfied with the quality and fitment of the product. Highly recommend, and PEX Supply had it at the best price!

                                      Should come with clear instructions about testing and replacement. And not changing specifications for particular use
