Direct answerA lap pool needs a clear swimming line.
What to check first
Keep steps away from the lane.
The existing pool, property access and equipment condition can change the answer. Record what is happening before adjustments are made.
What affects the work
Use even lighting at the end walls.
A clear scope should separate inspection, repair and optional improvement work. This makes quotations easier to compare.
When a site visit is useful
A site visit is needed when the answer depends on pipework, water loss, structural movement or the exact equipment installed. Photos can narrow the likely cause but cannot confirm a concealed fault.
