The first step in the renovation should be the reconstruction of the waterway. Some houses already have hydropower routes when they hand in their houses, but not all of them can meet the needs of the owners. What's more, the material of the water pipes opened by the business operators will not be ideal. The material of this concealed engineering water pipe is very important. If you want to use it without problems, you must choose a better material for the water pipe. Only in this way can you install a safe home. Today we will take a look at the waterway reconstruction. The relevant knowledge.
| The meaning of the waterway transformation: |
Hydropower renovation is the first step in the entire renovation process. No matter how you save money, you should first take quality as a prerequisite. Refers to the renovation of all or part of the waterway used by the original developer according to the decoration configuration, family population, lifestyle, and aesthetic concepts. General and circuit transformation are collectively referred to as hydropower reform.
| Waterway transformation process: |
The construction personnel determine the positioning point with the owner according to the design drawings → The protection of the finished product at the construction site → The line of the strike line according to the route → The fixed water card according to the line of the bullet line → The slotting according to the line direction of the elastic line → The cleaning of the residue soil → According to the size of the site → The top surface of the wall Fix the water pipes → check if there are any errors in the circuit → press and accept the water pressure and accept the test (it is an acceptance project, see the next article about water and electricity acceptance knowledge) → closed water tank
| Waterway modification considerations |
1. The renovation of home-built secondary waterways follows the principle of “walking on the water†and is easy to maintain at a later stage, without significantly increasing the height of the ground without affecting the floor height.
2. Household decoration waterway commonly used reference size data (size is based on untreated wall data): shower mixer hot and cold water pipe center spacing 150MM, from the ground 1000-1200MM; upper flip washing machine nozzle height 1200MM; electric water heater The height of the water supply port is equal to the net height of the floor - The distance from the top of the electric water heater is fixed - The diameter of the electric water heater is -200MM; The height of the water basin of the basin is 450-550MM; The distance from the toilet water outlet is 200MM, and the distance from the center of the toilet is generally 250MM on the left; The water outlet is 200MM higher than the pool itself. Other water supply and drainage dimensions are determined according to the product model.
3. The waterway reconstruction strictly follows the direction and positioning of the design drawings. During the practical operation, it is necessary to contact the relevant product manufacturers through the owners to master the different types of cabinet treasures, net water softeners, washing machines, water basins, bath water mixers, and water heaters. The position and size of the water supply and drainage port required by other models shall be such that the operation of the equipment cannot be installed in the future.
4. Generally speaking, it is right in the direction of the water supply outlet, and it is right cold and left hot (except for special requirements for individual equipment).
5. Pipe cutting: The pipe is cut with a special pipe cutter, and the bayonet clip should be adjusted to match the diameter of the pipe to be cut. When rotating and cutting, the force should be evenly applied. The broken pipe should be straight and smooth without burrs.
6. PPR pipe welding: PPR pipe using hot melt connection is the most reliable, interface strength, higher security performance. Before connecting, remove dust and foreign matter from pipes and accessories. After the connection is completed, you must hold the tube and fittings for sufficient cooling time to let go.
