Print the record for the fixture you are working on
Page 1 is for a conventional toilet seat. Page 2 is for a faucet outlet aerator. Print only the page you need, or keep both in a bathroom parts folder. These are blank handwriting records, not scale drawings or drilling templates; the PDF has no fillable fields.
Write the location and fixture model first. Record units and endpoints with each measurement. Use UNKNOWN when evidence is missing and N/A only when a field does not apply. Keep the original part or a labeled photo until the replacement has been checked.

Page 1: keep the bowl and the candidate seat separate
On the left side of your comparison, record the toilet’s actual measurements. On the other side, record the chosen seat’s requirements from its drawing. Do not fill a missing toilet measurement by copying the product specification.
Scroll across to read every column.
| Field group | What belongs here |
|---|---|
| Identification | Location, toilet model, existing seat code, photo filenames |
| Measured bowl | A: fixing centers; B: fixing line to front; C: outside width; D: rear space; units |
| Mounting access | Underneath accessible / concealed / other / unknown; existing hardware description |
| Candidate | Full seat code, drawing revision, specified mounting kit, required access |
| After fitting | Alignment, intended support, raised-lid movement, secure fixing and result |
Page 2: identify the complete aerator order
Record the full faucet model before the appearance of the outlet. Keep a measured diameter separate from a manufacturer-confirmed thread. “About 24 mm across” is an observation; M24×1 is a designation that still needs to be verified for that part.
Scroll across to read every column.
| Field group | What belongs here |
|---|---|
| Existing outlet | Housing / integrated thread / spray head / unknown; markings and photo references |
| Connection | Which part was measured; diameter and units; confirmed full thread and evidence |
| Replacement | Exact code; complete assembly or insert; approved flow and stream |
| Supporting parts | Seal specification and package contents; matching service key |
| Result | Joint dry; stream acceptable; original symptom resolved or still present |
Turn an unknown into a specific question
A useful supplier question names the fixture and the unresolved field. For a seat: “This toilet’s fixing access is enclosed. Which mounting kit is specified for this toilet and seat combination?” For an aerator: “Does this exact replacement code include the seal and require a separate key?” Add the recorded model and photo rather than a general request for a universal part.
In a hypothetical seat record, A = 5½ inches and B = 18½ inches can narrow the bowl family. If mounting access is still UNKNOWN, the order remains on hold. In a hypothetical aerator record, a confirmed thread but no flow specification is likewise only a partial match.
After fitting according to the manufacturer’s instructions, date the result and keep the successful part code. Mark any unresolved symptom separately. A correctly fitted seat does not repair a running toilet; a new aerator does not prove that an upstream restriction has gone away.
