Hydropower transformation depends first on whether the laying of water pipes and wires is reasonable. If the water pipes and wires are not embedded according to the specifications, it will be difficult to confirm the positions of the water pipes and wires after the hydropower transformation is completed. The waterproof of the bathroom extends directly from the door of the bathroom to the corridor, and then the corridor wall outside the bathroom is also waterproof, which is also an auxiliary means to prevent moisture regain. Water is pervasive, waterproof treatment is very important in decoration, waterproof also has aging process, and the quality of waterproof materials directly affects the service life of waterproof. Waterproofing technology directly affects the tightness of waterproofing.

Drainage pipe diameter: sewage pipe diameter is 1 10mm, caisson branch pipe diameter of toilet and kitchen is 75mm, and balcony drainage pipe diameter is 50 mm. It is forbidden to use conduit instead of air conditioning drainage pipe. The circuit needs to pay attention to the loop problem, shunt loop, one loop in each space and one loop in high power. There are high-power appliances in the kitchen and bathroom, which need large-scale wires. Power socket conversion, switch panel conversion, waterway conversion, cable TV line conversion, network line conversion, telephone line conversion and reasonable expenses. In this way, excessive additional costs can be avoided.

When positioning water and electricity, please ask sanitary ware merchants and water and electricity masters to discuss the location of household appliances with them that day. At the same time, consider the installation lines of gas water heater, electric water heater and TV. Water and circuit renovation can be divided into two prices: slotting and slotting. Some decoration teams divide the slotting price into "non-load-bearing wall slotting and load-bearing wall slotting". We must discuss the prices of different items in advance.

Exposed installation can save a lot of wires. The surface decoration can't give you an independent layout of each house. On the contrary, compared with concealed installation, the probability of failure is much greater. Adjacent bedrooms and even the neutral line of the guest dining room can be used. The advantage of concealed water and electricity installation is that it is beautiful and does not occupy indoor space. The disadvantage is that it is not easy to maintain. Whether it is necessary to bring dark clothes for hydropower decoration depends on the situation. If it is an old house renovation, it is generally recommended to install it openly. If it is a new house decoration, it is generally recommended to hide it.
