So we live in a crappily built house. The house itself is built well, but everything inside is not. The main thing we always have problems with is our toilets. Obviously it's the pipes or something. So about 2 years ago, it all started, us needing to get our system pumped. So we did, and it's been happening continuously, but now more frequently. In April, we had our system pumped because I was in the shower and the toilet started bubbling. I assumed that's what it needed because the first time that happened, two weeks later, there was no water in the toilet and crap was going into our bathtub because it was backed up. So today, I was in the shower, and it started bubbling and the tub, after I got out, took forever to finish draining and there wasn't even that much water in it to begin with. Also, about two months ago, my mom freaked out because she thought her toilet was about to overflow, it didn't though. But between when that happened and today, the toilet when we would flush them would make weird noises as if the water was going out of the toilet to fast or it would sound like I broke the flusher. A different noise came out of the toilet every time it got flushed. Sometimes, it sounded normal and sometimes it sounded like it was about to do something it shouldn't. So what's wrong with our toilets or pipes? I don't think the system needs to be pumped, so what is it? Help??
Sorry this is long, but I figure, the more information, the easier it is to tell what's wrong.
