1. How much is the hydropower renovation of the old house?
1. The price of hydropower renovation of old houses needs to be determined according to the housing area, complexity of hydropower structure, construction technology and other factors. Spend one more demolition cost than ordinary hydropower transformation.
2. At present, the price (contract and materials) of hydropower renovation in the market is 60- 100 yuan/flat. Take a house with 100 square meter as an example, the overall hydropower transformation needs 6000- 10000 yuan (excluding the demolition cost).
3. For the old house, the original water and electricity should be checked before the water and electricity transformation, and the reservation that can continue to be used should be checked. A house of 100 square meter, if all the original water and electricity are removed, it will cost about 3000 yuan to remove it.

Second, the old house hydropower renovation matters needing attention
1. Because it is an old house, it is necessary to dig the wall and bury the line again when carrying out hydropower transformation. Most of the previous communities used 1.5 or 2.5 square meters of wires, which had serious security risks and had to be demolished and rebuilt.
2. When installing the socket switch, there is no fixed requirement, and it can be arranged reasonably according to the actual use situation at home. In this process, it is necessary to synthesize the suggestions of the masters.
3. The distance between strong and weak electricity has a certain emphasis. In general, the distance between the strong and weak current junction boxes should be greater than 500mm, and the parallel distance with the ground should not be less than 200mm, so as not to interfere with each other.
4. Waterway route should be paid attention to in the hydropower transformation of old houses. If the water pipe and the wire are on the same plane, the water pipe should be kept below and the wire is above, and the water pipe will leak and drip on the wire, causing safety accidents.
3. What materials are needed for hydropower transformation?
1, waterway material
The materials for waterway reconstruction are mainly divided into toilet and kitchen. Toilets need toilets, PPR pipes, faucets, basins, towel racks, towel racks, cosmetic mirrors, etc. The kitchen needs PPR pipes, faucets, sinks, etc.
2. Circuit materials
The circuit transformation at home is more complicated, involving every room, and wires are used more. Wires are divided into strong wires and weak wires:
(1) Strong wire material: distribution box, hard wire and flexible wire.
(2) Weak wire materials: network wire, cable, single-core wire, audio-visual wire and network crystal head.
(3) Others: cassette, special wire tube, metal wire tube, plastic wire tube, street lock box, horizontal tube, straight head, etc.
