The home itself is an old house and needs a certain degree of renovation. How should the sewer pipe be renovated and what problems should I pay attention to?
这块，假如在能使用的准则下，能不改则不改，这是一个大前提。 The drainage pipe , if it can be used, can not be changed, it is not changed. This is a major premise.
As for the calculation of this cost, it is generally based on the extension of the meter in practice, and the meter is counted as many meters as the transformation. However, if there are special circumstances in the local area, it is necessary to communicate with the reformed unit before.
排水管 多是采用的铸铁管，假如要想把本来的 排水管 的铸铁管改成PVC管，许多旧式铸铁管尺度达不到，扣不了要改的PVC管，许多PVC管现在直径是50或者是40的管，在刺进铁管之后必定要把衔接的问题处理好。 And now, for many old-style rooms, the drainage pipes are mostly cast iron pipes. If you want to change the original cast-iron pipes to PVC pipes, many old cast-iron pipes ca n’t reach the standard, and you ca n’t buckle the PVC pipes to be changed. Many PVC pipes are now 50 or 40 in diameter. After piercing into the iron pipe, the connection problem must be dealt with.
