DO NOT BUY As you can see it is missing a critical part. On the original there is a hole beside the inlet and outlet. This is what turns the valve on when you twist it into place. This supposed copy doesn’t have that so it doesn’t work. It also took 2 weeks to arrive and now I have to send it back and order a different brand.
