Work before the hydropower stage

1, air conditioning workers to complete drilling.

2, heating equipment such as floor heating, conversion radiators, should be laid first

3, determine the design of the cabinet, the location of the water and the flue

Summary of 39 issues to be considered for waterway reconstruction:

(a) The design of the waterway should first consider all the equipment related to water, such as: water purifiers, water heaters, kitchen treasures, toilets and wash basins, etc., their location, installation methods and the need for hot water;

(2) Whether it is better to use gas or electric water heaters in advance and avoid the temporary replacement of water heaters, resulting in repeated alteration of the waterway;

(3) In addition to leaving the bathroom with wash basins, toilets, washing machines and other water outlets, it is also advisable to take one of them out. Afterwards, it is very convenient to pick up water from the floor.

(D) After the location of the washing machine is determined, the drainage of the washing machine can be considered to be inside the wall of the drainage pipe, which is beautiful and convenient;

(5) There should be two pressure tests after the waterway reconstruction, but nowadays, many decoration teams do a pressure suppression;

(6) It is advisable to have the property present in the pressure test, which can play a supervisory role; because some decoration teams will deceive the owners in this section. The method is: When the pressure is applied, open the “return valve” of the pressure pump to form a loop. Although the pressure pump seems to work, there is not much pressure in the tube. Especially for the electric pressure pump, the students should pay more attention.

(7) When picking up the house, check whether the drains in the kitchen and the bathroom are unobstructed. If the drain is slow, the property should be dredged in a timely manner. During the renovation, the drain outlets should be protected, especially during the tiled kitchen and bathroom. Cement falling into the drain leads to plugging;

(8) After filling the kitchen floor tiles, check the discharge of water to see if the floor drain is smooth (to remove the drainage speed after the floor drain covers, because most of the deepwater floor drains have the problem of slow drainage);

(9) If the extra floor drain is to be sealed off, the gap between the drain pipe and the floor drain must be blocked to prevent the overflow of the water.

(10) Earlier, Zhang Gong recommended the Songshan Deepwater Sealing Leakage at the forum. When the deepwater sealed floor drain is used in the future, it must be cleaned up according to the use situation. Otherwise, the rubber pad below the floor drain will not be able to seal off the dirt after hanging the dirt.

(11) It is also very important that the floor drain of the washing machine is best not to use a deep-sea floor drain. The master of washing machines in my house listened to the deep-water seal leakage I used. I said: "This deep-sealed washing machine has nine under-floor leaks. Go to the water." The result was unfortunately my family became the 90%. The main reason is that the deep water seal leakage has a common feature is the slow water, used in showers and other locations, deep water seal leakage, due to the small amount of water, floor drain can basically meet the needs of drainage; but the drainage speed of the washing machine is very fast With large displacements, the speed of water leakage from deep water seals cannot be met, resulting in direct water spillage.

(12) When the waterway is reconstructed, attention should be paid to four points for the installation of electric hot water heaters, sub-tap and other reserved cold and hot water pipes.
1, to ensure that the spacing of 15 cm (now most of the electric water heaters, sub-faucet hot and cold water on the water spacing is 15 cm, there are individual 10 cm);
2. The height of the hot and cold water nozzles is the same;
3, cold, hot water supply pipe vertical wall surface, after the wall tile should also be careful not to let the bricklayer get it wrong (not vertical, then the installation can be strenuous);
4, cold, hot water on the nozzle should be higher than the wall two centimeters, shop walls should also be asked bricklayers finished after the completion of wall tiles to ensure the same level of wall tiles and water pipes. If the size is not appropriate, after installation of electric water heaters, sub-tap, etc., it may be necessary to purchase an additional pipe hoop, inner wire and other connectors to complete the installation;

(Thirteen) Do not forget to do waterproofing on the bathroom floor, especially on the ground. If the shower area is not a closed shower room, the waterproof surface of the wall should be 180 cm high to prevent the wall from sweating in the future. Before closing the cement, we must do a 24-hour water-retention test.
