TRUDESIGN 28mm Non-Return Valve – Marine Water Backflow Stopper | JAYCAR

Water creeping back into your tank when you're not siphoning? That slow reverse flow is going to cost you more than a valve. This 28mm non-return valve sits inline, stops the backflow dead, and stays shut thanks to a stainless spring that won't corrode or stick open. Glass reinforced nylon body keeps it light and stiff while shrugging off diesel, petrol, and antifouling paint. Drop it in, follow the white arrow for flow direction, done. No extra fittings needed
