Reduction of evacuation

Adjust your diameters with precision thanks to our PVC drainage reducers!

In a domestic drainage system, it is common to need to connect pipes of different diameters, for example to link a washbasin or sink drain to the main collector. At Jardiboutique, we offer a complete range of grey PVC reducers, designed to guarantee a smooth, fully watertight transition. Whether for an eccentric or built-in reducer, our fittings let you adjust your pipework to current sanitary standards while optimising the space available in your walls or under your fixtures.

Made to withstand wastewater and household cleaning products, our PVC drainage reducers ensure gravity flow without retaining debris. Available in all standard plumbing sizes (40/32, 50/40, 100/50...), they are the key component for a clean, functional installation. With Jardiboutique, enjoy professional connection solutions for perfect flow management in your home.

Jardiboutique's technical tip: The direction and type of reducer are essential to avoid blockages. Flow tip: Always favour "eccentric" reducers for horizontal runs. By placing the flat side upward, you prevent air pockets from forming and make it easier to drain sediment at the bottom of the pipe. Installation: When gluing, make sure the reducer is fully inserted to the stop to avoid any internal ledge that could catch debris. Did you know? Using a built-in reducer (which fits directly into the socket of another fitting) is the ideal solution to save space in complex assemblies behind a bathroom cabinet.
