Jerry, I've been watching some videos in YouTube. Really rivetting stuff - unclogging blocked sewage drains. What amazes me is that the drains come into manholes which just have half-pipe chanels in them. Don't you get a lot of smell from them? Also, in towns it seems that the sewage drains run across properties, picking up from each house as they flow towards the mains.
Also the houses seem to have water pipes running all over teh place from the hot water boilers. I understand that the hot water feeds through radiators in rooms, but with all that water to be heated, and then for it to lose its heat, what are heating costs like?
Finally, and a bit yucky, those drains always seem to be clogged with what the plumbers call "wipes". The look like handkerchief-sized cloth. Don't they have bum fodder that breaks up in the water as it goes down the pipes?
