Plumber Negligence? New sewer

[Karla Villanueva]

I hired a big known company to check a clogging issue, I have a 1 acre lot with two homes on it, the home towards the back had the continues clogging issue, so company said I need it new sewer line, I installed it but after installing my water bill went from $200 to $800!! When front house has water and back house water valve is off, the meter stops spinning, it starts spinning like crazy once I open water valve for back home where the sewer line was installed. Plumber did not find any leaks inside the home and I know they broke a water line while digging , I made them dig again to expose water line, they dig only the back where they did the work  and still no visible leaks! I don’t know what could gone wrong but meter running high  happened the same day of the sewer installation. Water pressure is good but is also not as strong as it was

@Karla Villanueva  Can you bypass the water line in the ground between the front and the back house and see what happens.
