New Construction Plumbing Done Right in Altadena

New construction plumbing is one of those things that nobody thinks about until something goes wrong. And by then, the walls are closed, the floors are poured, and fixing a bad install is a nightmare. That's exactly why we take the rough-in stage seriously - it's the one window you have to get everything right.

Here's what we were working with on this Altadena build: a full DWV (drain, waste, and vent) system plus water line rough-in, all set into the floor framing before the structure gets any further along. The DWV stacks are plumb, properly strapped, and positioned exactly where each fixture needs to land. The blue PEX water lines are already routed and capped off, ready for pressure testing down the line. Every penetration through the framing is clean and accounted for.

The hose bib detail is a good example of how we think about new construction work. A lot of guys treat exterior bibs as an afterthought. We set ours with a proper copper stub-out, a ball valve, and a solid backing block - so the builder has something reliable to work with from day one, not something that'll need fixing before the landscaping is even in.

On a build this size, coordination matters. We're working around other trades and a tight framing schedule, so our installs need to be clean enough that they don't create headaches for whoever comes after us. That means labeled lines, capped stub-outs, and nothing left loose or guessed at.

Good plumbing on a new build isn't just about passing inspection. It's about setting up the people who will live in that house for decades without ever having to think about what's behind the walls.
