Your main water and sewer lines connect your building to the outside world and, when broken, can wreak havoc on your operations. Without a functioning main line, you are truly out of luck until the pipe is repaired. If you suspect a leak in your main sewer or water lines, contact your city. It may be their responsibility. If you are unsure of the problem, reach out to your local plumbers, like John’s Sales and Service, to come and take a look.
