I live in a trailor park in a single wide trailor. Our water froze, but we got it thawed. Now we think the sewer is froze, but it is 40 degrees outside. I removed some of the skirting so the warm air can pass through. It still won't go down. I don't have the money for a plumber to come. I am wondering if I should try to run a snake down through. Please any suggestions will be greatly appreciated.. Thank You!!
