15mm Single Check Valve
Does the job but not strong
The valve body is too thin, the ball valve distorts when tightening with spanner, with only a moderate ammount of force. You end up gently squeezing the body with a set of mole grips to reseat the plastic ball inside, its not much, but you can blow through the valve. Once fixed onto the pipework, its a bit of a gamble weather to give it that extra "nip" up.
