Debating whether to attempt a plumbing job myself or pay someone to do it. In theory it should be simple, and I spent an hour or so yesterday tracing pipes to try and make sense of a room in my basement that looks like someone tried to blow up a pipe factory. It's always interesting seeing a bathroom from below the floor, trying to figure out which bits are what.
Eventually I figured out which tap I need to close to isolate the part I want to work on. The downside is that the same tap also shuts off the water to the shower and to the kitchen sink. At some point I want to rejig everything to use a water manifold so I can do things like isolate the shower without turning off the toilet, but that's a larger job than I want to be attempting today. That's the sort of thing I'd probably look to do a piece at a time - get the manifold in place and then transfer item by item to the new feed. Separating out the parts of the shower room involves crawling into a desperately small space and I'd really rather not be doing that when it's either very cold or very warm. Interestingly, under the floor of the shower room I can see the stone steps that used to lead to the back door, before the house was extended. Lots of history in this house.
