It is often seen that many people complain on the Internet that they are suffering from losses when they are renovating. In fact, looking for workers or decoration companies is just like finding objects for us. If you find the right person, you will get married and comfortably spend a lifetime; if you find the wrong, there will be a lot of trouble, such as bathroom leaks, voltage instability and so on. For ordinary people like us, there may be only one chance to renovate the house in one lifetime. Therefore, we must be very cautious when decorating the bathroom, especially in the bathroom water and electricity, it is not only related to our daily life, but also related to our safety. Bathroom decoration knows the roots, beware of bathroom water and electricity construction being deceived.
Part1: There are many problems with the installation of pipelines in the bathroom water pipes.
Waterway renovation is the top priority of home decoration, just like human nerves and blood, giving life to the house. Therefore, before installing the water pipe, not only the position of the water outlets such as the wash basin, the toilet, the washing machine, etc., but also the water supply pipe should be selected. material.
Outstanding problem: the problem of waterway direction
In the bathroom decoration, the water pipes are laid from the ground. Many households and construction teams choose to lay pipes on the ground in order to save materials and shorten the construction period. Although it saves materials and construction difficulties, it is not conducive to future pipeline maintenance, and it is laid underground. Water pipes are vulnerable to damage.
Anti-fraud advice: water pipes go to the top
To ensure the safety of waterway construction, it is necessary to use standard qualified water pipes and pipe fittings products, and strictly operate according to the construction specifications. All waterways are completed and must be tested. When laying, it is best to route from the top or the wall, the amount of pipe may increase slightly, but it is conducive to future pipeline maintenance.
Rectification plan: pressure test water must pay attention
If conditions permit, remove and rebuild the unqualified and non-standard construction projects; strictly carry out the pressure test standard for pressure test. Metal and composite pipe test pressure 0.6MPa, voltage regulation for 10 minutes, pipe pressure drop should be no more than 0.02MPa, no leakage; plastic pipe test pressure 0.8MPa, voltage regulation for 20 minutes, pipe pressure drop should be no more than 0.05MPa, no leakage.
Part2: Drainage pipes must be inspected for domestic water protection
Drainage pipes are systems consisting of pipes that collect and discharge sewage, wastewater and rainwater and their associated facilities. In the renovation, waterproofing is often more important than any other topic. What should you pay attention to during the installation and use of the pipeline?
Outstanding problem: drains are often blocked
The quality of water supply and drainage pipes and fittings does not meet the standard requirements and affects the use. Before and after the construction, the pipeline was unchecked, the pressure test was not standard, the pipeline leaked or the debris entered the pipeline, and the quality was not up to standard.
Anti-fraud advice: check whether the drainage is smooth
Standard qualified water pipes and fittings must be used and operated strictly in accordance with construction specifications. After all the waterways have been constructed, they must be pressure tested and no leakage should occur. The installation position of the valve and faucet should be correct, the use is flexible and convenient, the water discharge is unimpeded, and the water meter is working normally.
Rectification plan: dismantling and rectification
If the conditions permit, the unsatisfactory and non-standard construction project shall be dismantled and re-constructed and strictly subjected to the pressure test standard for pressure test. Under the premise of satisfying the use, the valve, water meter, etc. may be in a relatively concealed position or properly decorated on the surface.
Part3: Switch socket carefully installed wire color is good class
The switch socket is an important part of the circuit installation. Don't underestimate the small socket, the installation location, the wires used, whether the installation is correct, etc. These problems need to be noted.
Outstanding problem: the color of the wire is different
The color of all the modified cables in the same set of houses is not uniform. The same phase, the colors are inconsistent, the cable properties cannot be resolved in the future and cannot be repaired.
Anti-fraud suggestion: uniform color of wires
Strictly in accordance with the electrical engineering construction specifications, the phase (fire) line should be unified, the zero line should be blue line, the ground line must be yellow-green two-color line.
All unidirectional sockets should be based on the principle of "left zero line right fire line middle ground line" or "upper fire line lower zero line" connection. Air-conditioning power supply generally adopts triangular plug. The socket with protective valve should be used in the height that children can touch. The bathroom, washing room and bathroom should be equipped with waterproof socket. The installation height should be no less than 1m, and should be away from water.
Rectification plan: the installation location must be correct
The protective grounding wire connection of the socket connection and the connection wire position of the phase line and the neutral wire must comply with the relevant provisions of the construction acceptance specification. The leakage switch used by the socket should be sensitive and reliable. Strong and weak power / switch socket installation position should be correct, pay attention to check the power supply.
Part4: Electrical acceptance is done in a strong position
Electricity is a good and dangerous thing. Modern life is inseparable from electricity. However, if the electrical engineering installation is not standardized or unqualified, it will cause irreparable regret. Let's take a look at what electrical care needs to pay attention to.
Outstanding problem: strong and weak electricity is not in charge
Whether the color of all the transformation lines in the same living room is uniform and whether the bottom box is correct. Whether the strong and weak wire head in the bottom box is kept 15-20cm long, whether the strong and weak wires are threaded, otherwise the strong and weak electricity will affect each other, and whether the TV or telephone computer audio uses a special line.
Anti-fraud suggestion: in charge
Check whether the strong and weak electric sub-pipes are in position, and whether the springs are naturally bent by the spring at the corners of the line.
Suggestions for rectification: rectification must be done
If conditions permit, remove and rebuild the unqualified and non-standard construction projects. The head of the household must be present at the time of water and gas acceptance, and immediately find the problem to rectify the construction and re-acceptance.
We must know the basics of bathroom decoration. The above is the Xiaobian for everyone to beware of the water and electricity construction of the bathroom. I hope to help everyone in the bathroom decoration.
