Source Library
Guides link to the most relevant source for the claim or decision at hand.
Primary sources
PlumbAdvisor prioritizes manufacturer owner manuals, care instructions, parts diagrams, product labels, and technical support pages when a guide depends on a particular fixture or appliance.
Public guidance
For water use, drinking-water safety, accessibility planning, and similar topics, guides may link to public agencies, utilities, health authorities, and standards bodies. A source should be close to the claim it supports rather than listed as a generic reference.
Limits
A source page does not replace local inspection, utility, or professional advice for a specific property.
