When we arrived the customer said he has a leak in the parkway. He told us he called the city and they said it is not their issue or their cause of this leak. We noticed that the leak the customer is talking about is a domestic line leak. There are no leaks in the lateral lines or main line there is just a domestic line. We also saw that the double check was leaking a little amount so we told customer if not repaired it will cause furthermore damage.
