Hot tap water pipe joint leakage, what method can be repaired?
The original hot connection place cut, a new joint with a pipe section, and then pick up
If the water pipe is thicker, you can use the hot melt machine directly in the external welding, the gap will be blocked, this method can not have too high pressure.A solder gun can also be used to spray solder directly into the solder joint, which can be used with the PP-R patch.
Also can use glue, glue in general, more suitable for low pressure pipeline, operating pressure should not exceed 4 kg, this method is not suitable for PP-R products, because the PP-R material determines the glue is generally difficult to dissolve.
The best cut off a re installation, as long as not concealed pipes into the wall should be implemented, and the most thorough, because the advantages of PP-R pipe is higher than the local welding strength, ensure tightness of the whole pipeline.
