Learn the most important rules regarding plumbing installations
We have already drawn your attention to the fact that a proper plumbing installation in the home translates to comfort, safety, and savings. At the same time, it is worth remembering that pipes should be resistant to high temperature and pressure, and the entire system should be designed in accordance with European norms and standards (PN-EN 1717). These specify, among other things, the standard placement of connections. By following these rules, you will avoid the most common mistakes and ensure the smooth operation of the entire home's plumbing.
- Cold water on the right side, and hot on the left. Such an arrangement means every user will instinctively set the correct temperature, and the installation will comply with the manufacturer's existing guidelines.
- Choose high-quality pipe materials. They can be made of plastics, copper, or steel.
- Opt for elements that are resistant to high temperatures and corrosion to avoid issues with waste and potential blockages.
- Ensure the appropriate diameter of the pipes. They must be adjusted to the number of receivers and also to the preferred efficiency.
- Do not forget about the proper slope of the pipes. Incorrect settings can also lead to water accumulation and blockages.
- Maintain a constant lukewarm water setting. Proper connection of mixers and thermostats allows safe use of the shower and protects us from sudden temperature changes.
Which side for cold water, and which side for hot water?
The solution where hot water is on the left and cold water on the right makes it possible to use the tap safely and intuitively. However, if the water is routed the other way around, the solution could be a traditional mixer tap. Any good plumber can easily handle this.
Ensure proper water connection in your bathroom and kitchen
Good water connection in the building requires care in the installation of valves and considering all points from which household members will draw water. You need to remember that proper supply of cold and hot water ensures user convenience and safety. Adhering to the manufacturer's guidelines and installation standards effectively minimizes the risk of failure. After all, you certainly do not want to have to use additional service services.
