How do I find the right pipe diameter?
Each of your pipes has a specific purpose and it is also necessary to take into account the diameter of the pipes, which differs depending on the plumbing equipment they connect. This diameter will indeed have an impact on the pressure and flow of water at the outlet of the taps on the one hand (for the supply pipes) and on the volume of water evacuated by the force of gravity over a period of time. given on the other hand (for drain pipes). In plumbing, there are many diameters, ranging from 10 millimeters to 10 cm.
Within a house, the tubes intended for the supply of sanitary facilities will generally go from 10 mm (the most frequent diameter for the supply of the toilets) to 16 mm (supply of bathtub, of shower), the sections of 12 mm and 14 mm used to supply the sink or washbasin taps. The largest sections (20, 25 or even 32 mm are reserved for risers which are used to bring water to the different floors of a building.
Regarding the sanitary drainage, the diameter of the pipes varies from 32 mm (for the sink) to 100 mm (toilet drainage), passing through the tubes of 40 or 50 mm section for the shower and the bathtub.
Once the tube is cut, chamfered and deburred, you can glue the two elements:
- Using emery cloth, roughen the parts to be assembled.
- Wipe off dust with a soft, slightly damp, lint-free cloth.
- Degrease the two parts to be assembled and let dry.
- Carefully glue both the pipe and the PVC fitting.
Do not wait and fit the tube into the fitting in a single gesture, wipe off the glue that flows back with a clean, lint-free cloth.
Advantages of this fitting
- Rather easy and seamless installation
- Low price
- Large choice of fittings
