Nobody photographs the inside of a wall. When the job is finished you see tile, paint and fixtures, and every plumber’s work looks more or less the same. The difference is in the parts you will never look at again, which is exactly why it is easy to cut corners there.
What Good Looks Like Behind The Drywall
- Straight, square, supported. Pipe run deliberately and fastened at proper intervals, rather than snaked wherever it fit.
- Protection plates. Steel plates where pipe passes through studs, so the next person hanging a mirror does not put a screw through your water line.
- Proper venting. Every fixture vented as it should be, so traps hold their seal and drains do not gurgle.
- Solid backing. Blocking behind grab bars, floating vanities and wall-hung fixtures, installed before the wall closed, because it cannot be added afterwards.
- Room to service. Valves and cleanouts placed where a person can actually reach them.
Why It Shows Up Eventually
Invisible work becomes visible in predictable ways. Unsupported pipe knocks when a valve closes. A poorly vented drain empties a trap and lets sewer gas into a bathroom. A vanity fixed to drywall instead of blocking works loose. A shower valve buried with no access turns a cartridge change into tile work.
Ask To See It
The best time to judge a plumbing job is at rough-in, while everything is still open. Walk the space with your plumber before the inspection, ask what each line does, and ask where the shutoffs are. Take photographs of the open walls with a tape measure in frame. That record is worth a great deal the next time anyone drills into a wall.
We expect those questions, and on our own jobs we photograph rough-ins as a matter of course.
