Use the main symptom to choose a route below. You do not need to know whether a cartridge, trap, pump, or buried line has failed. Each guide explains what to describe, what not to disturb, and which questions make the proposed visit easier to understand.
Water is appearing where it should not
Begin with an active leak if water is still escaping. Use the hidden-leak route for a stain or damp area whose source is not visible. A wet area around the heater has its own guide because equipment safety and damaged materials need separate attention. If the concern is outdoors, identify the supply arrangement before assuming the utility or owner is responsible.
Do not enter an unsafe area just to select a more exact category. The urgent safety page comes before any inspection when water, electricity, structural instability, or contamination may be involved.
A fixture no longer behaves normally
Choose the toilet, sink, shower, hot-water, or appliance guide that matches the changed behavior. State whether one fixture or several are affected. The page categories describe problems a visitor may bring to a provider, not a verified list of services offered by the person who answers the shared number.
For drainage, separate a slow opening from wastewater returning to the building. A pump alarm also needs the actual equipment and maintenance contact identified before work is arranged.
A planned visit can need a different route
If you already have a proposal, use the estimate page, repair comparison, or new-fixture checklist. These help define the work rather than diagnose a fault. The official resources page connects to permit, licensing, utility, and health-department information.
