Wow, that's actually some really clever engineering that went into making a hub for the utilities where the lines can all rotate together. I'd hate to be the one who has to fix it when something goes wrong though, it looks like a lot of that is probably bespoke, and replacing anything must be big $$$. Also it's hard to imagine that the sewage system is problem-free. I wonder if they have a masticator in the line somewhere.
For sure. Though, the sensors will pick up when the first of two seals break, you could potentially use the system while a replacement seal is being worked on. If you're feeling adventurous that is. ;)
It's three seals and two sensors. You're still technically good to go with both sensors going off for leaks. One leak is cause to buy a replacement seal and/or junction but it isn't a reason to move out.
