The owner of the new house changed the heating pipe during the renovation, but the developer delayed heating. If the pipeline leaks during the suppression process, is it the responsibility of the owner, the developer or the property? This situation has nothing to do with the developer and the property, because according to the normal procedure, after the renovation, you have to use a pressure pump to press out the qualified products before the next renovation, so you have to find someone to transform them. In addition, the specific cause of water leakage depends on whether it is an installation problem or a pipe quality problem. If there is a problem with the quality of the pipeline, you can also find the manufacturer.
