Bathroom decoration, knowing the roots, preventing the bathroom, hydropower construction, being deceived
It's common to see people complaining online about losses they face during home renovation. In reality, choosing workers or a decoration company is like finding the right person for life. If you choose wisely, it can lead to a smooth and comfortable experience; if not, you may end up with problems like bathroom leaks, unstable voltage, and more. For most of us, this might be the only time we renovate our home in a lifetime, so it's crucial to be extremely careful, especially when it comes to bathroom water and electrical work—these are not just about daily convenience but also safety.
Part 1: Issues with Water Pipe Installation
Water pipe renovation is the most critical part of home improvement, similar to the nervous system and blood vessels that give life to a house. Before installing the pipes, it’s essential to plan the positions of water outlets such as sinks, toilets, and washing machines, as well as select appropriate materials for the water supply lines.
Common Problem: Poor Water Pipe Direction
In many bathrooms, water pipes are laid on the ground to save material and time. While this approach reduces costs and construction time, it makes future maintenance difficult and increases the risk of damage due to underground placement.
Anti-Fraud Tip: Run Pipes from the Top
To ensure safe and long-lasting water pipe installation, use standard, high-quality pipes and fittings. Follow construction guidelines strictly and conduct thorough pressure tests after installation. It's best to route pipes along the ceiling or walls, even if it slightly increases the amount of piping, as this makes future repairs easier.
Remediation Plan: Pay Attention to Pressure Testing
If possible, remove and re-install any substandard or non-compliant projects. Conduct pressure tests according to standards: for metal or composite pipes, the test pressure should be 0.6MPa, held for 10 minutes with a pressure drop no more than 0.02MPa and no leakage. For plastic pipes, the pressure should be 0.8MPa, held for 20 minutes, with a pressure drop no more than 0.05MPa and no leakage.
Part 2: Drainage Pipes Must Be Checked for Waterproofing
Drainage systems collect and discharge wastewater, sewage, and rainwater. During renovation, waterproofing is often more important than other aspects. What should you watch out for during installation and use?
Common Problem: Blocked Drains
Poor quality pipes and fittings can cause blockages. If the pipeline isn’t checked before and after installation, or if the pressure test isn’t done properly, leaks or debris can enter the system, leading to future issues.
Anti-Fraud Tip: Ensure Drainage is Smooth
Use standard, qualified pipes and fittings, and follow construction specifications carefully. After installation, all pipelines must be tested for leaks and function properly. The valve and faucet locations should be correct, easy to use, and allow for unobstructed drainage.
Remediation Plan: Dismantle and Reinstall
If possible, remove and re-install any non-compliant work. Ensure that valves and water meters are installed in a concealed or appropriately decorated location, while still meeting functional requirements.
Part 3: Careful Installation of Switches and Sockets
Switches and sockets are vital parts of electrical installations. Don't underestimate the importance of proper placement, wiring, and correct installation.
Common Problem: Inconsistent Wire Colors
In some homes, wires of the same system have different colors, making it hard to identify their functions later, which complicates future repairs.
Anti-Fraud Tip: Use Uniform Wire Colors
Follow electrical construction standards. Phase (live) wires should be consistent, neutral wires should be blue, and ground wires should be yellow-green. All single-phase sockets should be wired according to the “left zero, right live, middle ground†rule or “top live, bottom zero.†Air conditioners usually require a three-pin plug. Install sockets with protective switches in areas accessible to children, and use waterproof sockets in bathrooms and washrooms, keeping them at least 1 meter above the floor and away from water sources.
Remediation Plan: Correct Installation Location
Ensure that socket grounding connections and phase/neutral wire positions comply with construction standards. The leakage switch should be sensitive and reliable. The placement of strong and weak power sockets must be accurate, and always check the power supply before finalizing.
Part 4: Proper Electrical Acceptance
Electricity is essential in modern life, but improper installation can lead to serious consequences. Let’s look at what to pay attention to during electrical work.
Common Problem: Confusion Between Strong and Weak Electricity
Check if the color of wires in the same room is uniform and if the junction boxes are correctly placed. Ensure that the ends of strong and weak wires are kept at least 15-20 cm long, and that they are properly separated to avoid interference. Special lines should be used for TV, telephone, and computer audio.
Anti-Fraud Tip: Keep Strong and Weak Wires Separate
Make sure that strong and weak electric conduits are properly positioned and that the bends are naturally formed using springs.
Remediation Plan: Complete Rectification
If possible, remove and re-install any non-compliant work. The homeowner should be present during the final inspection of water and gas systems, and any issues should be addressed immediately with re-inspection.
Understanding the basics of bathroom renovation is essential. The above points are key things to be aware of when dealing with water and electricity in the bathroom. I hope this information helps you during your renovation process.
