Valsir PP3® ensures a practical and rapid installation without the use of glues or special tools thanks to the jointing system with push-fit sockets.

The particular shape of the seal and the housing of the push-fit joint guarantee hydraulic tightness and allow the normal movements of the pipe including those caused by thermal expansion.

the thermal expansion of Valsir PP3® is extremely low compared to the most common plastic materials, a 3000 mm pipe will expand in length by just 13 mm when the waste liquid flows at a continuous temperature of 60°C.

It is thanks to this low coefficient of thermal expansion that the push-fit joints are capable of absorbing the variations in length of the pipe without taking any particular precautionary measures; it is enough to follow the installation instructions in the Valsir technical manuals.
