What should I record before requesting service for shower & tub?
Record the exact symptom, timing, affected areas, model or component identity, recent changes, safe observations, photos, and any displayed code.
What this means
Shower & tub covers drain, pressure, temperature, diverters, and leaks. Relevant observations include Tub backs up during a flush, Shower drains slowly, Tub spout and shower run together, Temperature will not stay steady, Water appears behind the wall. The correct response depends on age, design, climate, usage, installation, recent work, and the exact manufacturer instructions; these observations narrow next steps but do not prove a failed part.
