Very expensive for what it is
Just hope it does what it's meant to do. Very expensive for two bits of plastic and q wire spring. Should be about £5. Needed a bit of grease to lubenitnto slide it into the pipe so did spring at same time to protect from corrosion. Also need to be careful enough installing to ensure the shape is not distorted to ensure flap seals.
