I have two bathrooms in my home, one has a shower and the other bathtub. The shower has been stopped up for a long time now... the water was going out slowly now it doesn't go out at all... recently the tub in the other bathroom has stopped up same thing... the water was going out slowly, and now not at all... is this an inside problem or an outside problem. When we purchased the home we could tell that someone had been digging outside but not sure what the reason was... Please help if you can... We have tried most everything...
