Remodel plumbing: Lots of "thinking ahead"!
Bill wrote:
They say for plumbing, you only need to know two things. Poop does not flow uphill and the water valve is out front... Not so I am finding with old construction major plumbing replacement work! I've only done limited plumbing work before, replace a water line, add a new line, replace a valve, etc. But now I am ripping out an entire water system and replacing it in an old 2 x 4 wall house... And I'm learning this stuff is not easy! Lots of thinking ahead as to how you can and can't route the lines. The running of plumbing lines (including large drain and vent lines) is quite contrary to 2 x 4 structural support and wood framing! There are bearing and sheer walls which can't have large holes cut in them. Or 2 x 4 floor joists which simply can't have large holes cut in them (no room to add additional support). Seems to do plumbing work, you need to be a bit of a structural engineer! And you don't want to run a water line on an outside wall because it might freeze in winter. Or maybe if you run a hot water line up in the ceiling, it will retain its heat longer... ...And the pipe can easily be run up that wall, and across that ceiling, BUT you can't cut a large hole in the top plate at the corner because it is a major structural support! Adding a whole house water filter, you need to leave room below the filter so it can be removed for cleaning. And thinking of maintenance/replacement in future years, how would someone disassemble a section of pipe? Humm... Should add a union there! And on and on... I can't imagine how they did this with galvanized pipe way back when. (I'm using PVC/CPVC. I don't like PEX because I've heard too many tales of leaks.) I think I like electrical work much better. Small holes you can drill almost anywhere and does not need to go in a straight line. And electric lines do not freeze... Use PEX. Dealing with whatever leak that might pop up will be far easier than replumbing with conventional pipe. In the best case, PEX can only leak at one of two places: The manifold or the terminus. Standard piping has a dozen places, from the main supply to the faucet, it could leak. |

All done at the manifold. This eliminates another potential leak point. |
