Water supply of common sense

1, home decoration water pipe commonly used PPR pipe, steel pipe, copper pipe, steel pipe prices are relatively high, and PPR pipe fittings than the price of steel pipe fittings, copper pipe the most expensive, the price is equivalent to PPR pipe Of about 4 times.

2, home decoration laying water pipes should be avoided from the ground Shangpu, preferably from the top or wall alignment, the pipe may be a slight increase in the amount, but conducive to future maintenance of the pipeline.

3, hot and cold water pipe wall thickness is not the same, cold water pipes can not be used as hot water pipes, hot and cold water pipe is easy to distinguish hot water pipe has a red line mark.

4, PPR pipe standard length of four meters for each root, to buy time to ask businesses that is the price of each pipe or pipe per meter price, pipe to the future to remember whether the length of pipe inspection requirements.

5, home decoration water pipes should pay attention to diameter and wall thickness, the general Explorer to use 6 in charge, in charge of the optional 4 in charge of water, in order to ensure that water can also be used in charge of 6 in charge.

6, home decoration Pipe time to pay attention to the pipe diameter is symmetrical, caliber thickness will not affect the symmetry of the two interfaces docking.

7, Building Decoration Industry Association, "home decoration quality specifications" on the pressure test of the time and the size of the pressure there is such a requirement: newly installed water supply pipeline must be in accordance with the relevant provisions of the pressure test. Metal and its composite pipe test pressure 0.6MPa, voltage regulator 10 minutes, the tube pressure drop should not be greater than 0.02MPa, no leakage; plastic pipe test pressure 0.8MPa, voltage regulator 20 minutes, the tube pressure drop should not be greater than 0.05MPa, leakage.
