Please ensure that the 25 mm laying tube is fully inserted into the connections. When pushing the laying pipe into the connector, you will feel the first resistance after approx. 4 cm. This is the sealing ring that seals around the outside when the union nut is tightened.
Please then push the pipe a further 2 cm past this resistance. Only when the pipe is a total of 6 cm inside the connector (stop) should the connector be closed by turning the union nut.
Leakage: If the installation pipe is only pushed in 4 cm, the connection would be leaking - the same applies if there are grooves or scratches on the outside of the pipe, which could be due to careless handling of the pipe during installation.
