If you think there is a sewer stoppage, the first thing that you need to do is locate the cleanout, which is usually located in the flower bed near the front of the house. Check the cleanout to see if it is holding water. If it is not, then it is likely to be an internal problem. If it is holding water, then it might be a service line or main line stoppage. At that point you can contact an Affordable Plumber in Carlsbad California?
