Last winter my pipes froze and burst 
and I did not have water to all of my house til this Fall when we finally figured out the best way to re-do the plumbing for the entire house and it's a 2-part house to boot.
The answer was to have it all inside [Yea for indoor plumbing 
] and not under the floor where it had been and was only reachable by pulling up the floor. Remember – I float on a river.
The solution was PEX plumbing and here is Jesse and the PEX plumbing project. The connection between the two parts is outside but VERY well insulated… and besides PEX is not going to burst.
So glad this stuff exists.
Great idea! The weather is also one of the common reason why pipes are damaged. To prevent this you should know the type and the quality of the pipe that you are going to use.
Thank you for your comment. Weather related plumbing issues are common when it gets very cold! And in most floating homes, the plumbing is outside under the house so any arctic blasts cause problems. I now have “indoor plumbing.”
