Build the condition record
Build the condition record
- Record whether sound is constant or returns at regular intervals when no one flushes.
- From above without disassembly, note water entering the overflow tube or a chain caught under the flapper.
- Use a dye check only when the fixture is stable and follow the EPA instruction to flush afterward.
- Look at the floor, base, stop and supply connection for water before focusing only on tank parts.
Why the pattern matters
Why the pattern matters
A silent bowl leak, overflow-tube flow, fill-valve issue, chain interference or exterior leak can produce different symptoms. EPA suggests a dye observation for some toilet leaks, but visible cracks, movement, floor water, sewage signs or uncertain controls are reasons to stop and seek qualified help.
Questions the record should answer
Questions the record should answer
- Is water escaping tank-to-bowl, through the overflow, at a connection, or outside the fixture?
- Can the known fixture stop isolate it without force?
- Would repair parts match this exact model and flush configuration?
- How will the final check cover refill, flush, shutoff and floor dryness?
