Installing a new plumbing system is an essential step in any construction or renovation project. Poor design or errors during installation can lead to leaks, blockages or costly repairs in the long term. To ensure an efficient, long-lasting network, it’s important to avoid certain common mistakes. In this article, find out what they are and how to prevent them.
Common mistakes when installing a plumbing system
Poor network planning
A lack of planning is one of the main causes of problems in new plumbing systems. Failure to take account of equipment layout, drainpipe slope or structural constraints can lead to inefficiencies and complications.
Poor choice of materials
Using unsuitable or poor-quality materials can compromise the durability of the system. For example, choosing PVC pipes for high-pressure hot water can lead to breaks. It’s crucial to select materials that are adapted to the specific needs of your system.
Poorly made connections
Loose or poorly sealed fittings are a frequent source of leaks. Excessive Teflon tape or improperly applied PVC pipe adhesives can also lead to leakage problems.
Neglecting standards and regulations
In Belgium, strict standards govern the installation of plumbing systems. Failure to comply with these requirements can lead not only to inefficiencies, but also to penalties or refusal of inspection during compliance checks.
No slope in drainage pipes
Drain pipes require a minimum slope to ensure efficient wastewater flow. Insufficient or no slope can lead to blockages and backflow.
Network overload
Adding too many water points on the same line, or undersizing pipes, can reduce water pressure and lead to inefficiencies throughout the network.
Forget the safety devices
Failure to install check valves, air bleeders or strategic shut-off valves can leave the system vulnerable to leaks and malfunctions.
How can you avoid these mistakes?
Plan your network carefully
Work with a professional to draw up a detailed plan of the plumbing network. Identify the specific needs of each water point and ensure that pipes are correctly sized.
Use quality materials
Invest in suitable materials that comply with current standards. For example, use copper or PEX pipes for hot water and PVC for drains.
Check every connection
Make sure every connection is properly made, sealed and tested before finalizing the installation. When soldering, observe recommended temperatures and techniques.
Observe drainage slopes
For drainage pipes, ensure a minimum slope of 1-2% (i.e. 1-2 cm per meter) for optimum drainage.
Provide safety devices
Install check valves to prevent backflow, shut-off valves to facilitate repairs and bleed valves to remove air from the system.
Why call in a professional?
Even with good planning, installing a plumbing system remains a complex task requiring specific skills. A professional guarantees that the work is carried out to the highest standards, avoids costly mistakes and ensures that your system operates at optimum efficiency.
