How to write the property water pipe treatment process?

Waterway reconstruction is generally used in kitchens and bathrooms, and its importance can be seen. If it is not handled properly, it may lead to water leakage and seepage in the home, and the later maintenance is also more troublesome. As a basic project of home improvement, the waterway reconstruction construction must be cautious. The voyage of waterway reconstruction is generally divided into three steps: preliminary preparation, construction and acceptance. Let's take a look at the construction process of waterway reconstruction and see what needs attention.

First, the preparatory work before the waterway reconstruction

1. When selecting water pipes, the color of water pipes should be made clear first, and hot and cold water pipes should be treated with color separation sets. All hot water pipes are red, and cold water pipes are blue. Choose water pipes according to their colors to facilitate construction inspection and maintenance. If the colors are difficult to separate, be sure to pay attention to the installation direction of cold and hot water pipes (for example, the cold water pipe is placed on the left and the hot water pipe is placed on the right).

2. Pay attention to the material of water pipes when choosing water pipes. Not all materials can be connected with hot water. Generally, PPR pipes, PE pipes and copper pipes are used for both cold and hot purposes, but U-PVC pipes can't be used to connect hot water, so these pipes are mostly used in sewers.

3. The closed water test is very important. After waterproofing, water closing test must be done. If you find water leakage, you can find a property to solve it. If you don't do the experiment, the property will not be responsible for any problems in the future.

4. Before construction, we must reserve some water inlet and outlet positions, especially the decoration of second-hand houses, in case of future changes. For example, the cold and hot water inlet of vegetable washing pool, the inlet and outlet of gas water heater, the cold and hot water of shower, electric water heater or solar water heater, etc.

Second, the channel reconstruction construction

1. In waterway reconstruction, the connection angle between the pipeline and the elbow must be 90 degrees, otherwise the wall thickness of the pipeline on both sides of the elbow joint will be different, and the place with thin wall thickness may be in danger of leakage under the pressure of tap water because of uneven stress. In order to save money, some owners may put forward that "the pipeline can be pulled obliquely", which has buried the hidden danger of water leakage.

2. When installing waterway pipelines, the pipelines may not be long enough, and several pipelines need to be connected by straight pipes or pipe clamps in the middle. For buried pipelines, try not to have contacts. One more contact, one more leakage problem. If there is no leakage on the other side, try not to replace it, so as to avoid the risk of leakage of the original joint after replacement.

The waterway should walk on the roof of the house, so that if there is a water leakage problem in the waterway, the water will drip down, and you can immediately find out where the water leakage is. At present, aluminum gusset ceilings are widely used in kitchens and bathrooms. It is very simple to remove the ceilings and repair them immediately. Even if the water leaks, it will not leak to the neighbor's house downstairs, so as not to affect the neighborhood relationship.

4. The connection of water pipes must be carried out in strict accordance with the specifications, and the connection mode cannot be changed at will, especially for water pipes close to the circuit, which must be very leak-proof and airtight. Therefore, we must pay more attention when connecting the water pipes, and the layout should follow closely.

Three. Channel reconstruction acceptance

1. After the renovation of concealed works such as hydropower is completed, it is necessary to carry out suppression tests to avoid water leakage accidents in the future. When the water pipe pressure test pump is tested, the pressure has a certain range, and the greater the pressure, the better. Generally, the best pressure test water is 6-8kg, and the test pressure should not be lower than 0.6MPa for 20-30 minutes.

2. It can't be completely judged whether the waterway is in normal use only once, and it can be tested continuously after repeated suppression.

3. For the waterway reconstruction of the house, it is necessary to redraw the waterway, because it may not completely conform to the original design waterway map during the construction process, so it must be redrawn according to the actual waterway direction of the house, which is a necessary work after the waterway reconstruction.

The above is the introduction of the construction process of waterway reconstruction and the relevant contents of matters needing attention in waterway reconstruction, hoping to help everyone.
