METHOD FOR REPAIRING A WATER SYSTEM |
摘要 |
A method of repairing a leak, where there is a water network with a main shutoff valve. An isolation valve is inserted in the pipe a short distance upstream of the leak, and the leak is repaired by using the local isolation valve to keep water from the repair location. This enables the main shutoff valve to be opened and distribute water to the other areas of the network. The isolation valve is particularly arranged to become a permanent part of the water system after the leak is repaired. |
