1.Pipe installation must be looking for professional technicians.No matter how you decorate luxurious high-grade, if you are not willing to part with or use money in this respect ,it is not cost-effective.Often pipeline blowout or leakage, can cause conduit itself price several times, the loss of hundreds and even thousands of times.

     2.must be a pressurization test after installation.Pressure test is in commonly 1.5 times under the condition of water pressure, in the test should be no slack phenomenon.

     3.methods and steps without pressure test

 a. closed the main valve pipe

 b. opened the taps inside the room for 20 minutes, to ensure that no water after dropping off all taps.

 c. closed toilet and washing water switch.

 d. Turn on the water main valve.

 e.After opening the main valve 20 minutes to see if the meter walk, including slow to move. If you have to move, that is leaking; If you do not move, that is fine.

     4. The pipeline waterproof processing

     Foundation treatment: wide chisel along the nozzle around 10cm, 8cm deep base of the cone, the surface of the gravel, laitance, dust and other debris cleared. 24 hours before grouting, foundation surface should be sufficiently moist. 1 hour before filling should dry water; stir: By water: feed = 1:5 to determine the amount of water, stir the water should be used to tap water temperature to 5 ~ 40 ℃ is appropriate, can be mechanical or manual mixing. When using mechanical stirring, the stirring time is generally 1 to 2 minutes.Artificial stirring advised adding water 2/3 of stir 2 minutes, followed by adding the remaining water and continue stirring until evenly; Filling: According to the actual situation of the spout, select the appropriate grout way, because there grout nozzle good flow properties, the general case, the "filling weight method" can, coming directly from the nozzle side of the slurry poured into the slurry is totally dependent on the weight of the self-leveling and filling perfusion space. Maintenance: After grouting is completed within 30 minutes, immediately curing agents sprayed or covered with plastic film for conservation (maintaining a condensate plastic film), in the final set to continue watering grout layer moisture conservation.

      After filling, the mouth of the canal and the surrounding area Paokai water treatment, choice of flexible waterproof slurry water treatment, because flexible waterproof material with good flexibility, elongation properties. Able to withstand a certain degree of vibration and displacement. Brushing twice brushing, the total thickness of not more than 2mm. Note that when the next brushing pipe outlet, the pipeline must be appropriate waterproof. Recommended flexible waterproofing slurry coated pipe height of 10cm.
