THE LIMIT

One answer cannot certify a hidden condition.

Stop testing if water approaches electricity, finishes sag, wastewater escapes or a pressurized leak cannot be isolated. Licensed plumbing work may be required by local rules.

THE HANDOFF

Evidence makes the next step faster.

Share the exact fixture sequence, delay before symptoms, clean-water or wastewater indicators, accessible photos and shutoff behavior.
