When looking for a home, make sure it is connected to a sewer system and not a septic tank. Septic tanks get backed up on a regular basis and you will not be able to use your toilet.
This isn't really true ... not if the installation was proper ... there should be a clean-out just a few feet before the tank ... if the tank inlet is blocked or the tank is full, simply unscrew the plug ... all the household plumbing will work as expected ...
The downside is that now you'll have raw sewage spilling out on the ground by your tank ... but trust me on this one, the pump truck guy can fix that ...

Funny story I'd like to share ... not many but a few plumbers will confirm this ...
The first time this happened to me, I just blew it off ... one of those weird anomalies that occasionally come up ... Neptune was occluding Zyzzuvy's Star or something ...
The second time, I inquiried ...
Look ... I understand how damn slippery a woman's knickers can get, God knows how many have slipped through my hands ... but sewer systems are big enough around to handle a pair of knickers just fine ... it's not a problem if they slip out of your hands ... they'll be at the bottom of the tank soon enough, and I never asked the pump truck guy what he did with all the ones he was collecting ...
what I don't understand is teeshirt, bra, pants, socks ... a woman undressing and flushing her clothes down the toilet ... teenager sized clothing ...
Well ... the answer came back ... you guessed it already ... there was indeed a teenaged girl involved and she had just seen her flowers for the first time ... and panicked ... and just ... kept ... flushing ...
This happened a total of three time to me over 21 years and 16 units ... so this is surprisingly common ... at least some of the women posters here would have done this ... perhaps they could explain this better, it's certainly beyond me ... but something to keep in mind if you come across a particularly stubborn problem ...
