What shell and fitting details help an evaluator?
Fixed reference points help: the tile course, skimmer opening, returns, lights, steps, visible seams, and the level where water appears to settle. Record repeatable changes from a safe position, but do not assume the nearest crack, gap, or fitting is the source.
Use fixed visual references
From a safe position, note whether the waterline repeatedly settles near a particular fitting, tile course, or surface feature. Record dates and pool-operation context.
Document recent changes
Mention resurfacing, tile work, deck movement, storms, or equipment changes. Do not claim those events caused the water loss; they are context for the evaluator.
Let the visit determine the method
The appropriate test depends on construction, access, electrical safety, and the suspected area. Confirm what the professional plans to evaluate and what is excluded.
Build a surface-reference record
Photograph the same feature from the same safe location when possible. Note whether the mark changes after rain, ordinary pool use, cleaning, or water added. Include resurfacing, tile, deck, light, or fitting work as dated context.
Ask the provider which surfaces and fittings are included and whether access to lights, deep-water features, concealed joints, or the deck is excluded. Electrical lights and deep-water inspection require appropriate safety judgment.
Request a plain-language description of any narrowed area and the limits of that finding. A useful record distinguishes what was observed from what was not accessed or tested.
Quick answers
Frequently asked questions
Does a visible pool crack always leak?
No. Appearance alone does not establish whether water is escaping or what repair is appropriate.
Why record where the waterline settles?
A repeated level can give the provider a fixed reference for planning an on-site review, but it does not identify the responsible component.
Should I use dye around a fitting?
Not from this guide. Let an appropriate professional decide which method fits the pool, access, and safety conditions.
