You should not let someone patch the pool without testing it first because you may end up fixing the wrong thing.
A pool can lose water from a skimmer, light, fitting, drain, shell crack, plumbing line, equipment leak, spa line, or more than one place at the same time. If someone walks up, sees an old patch or a suspicious crack, and just patches it without testing, that does not mean they found the leak.
The customer risk is wasted money. You may pay for a patch, repair, skimmer work, light seal, or plumbing repair and the pool still keeps losing water. Now you are frustrated, the pool is still leaking, and the next person has to sort through the original leak plus the new repair work.
A Patch Can Also Hide Evidence
A patch can hide useful evidence. If the wrong area gets covered, it may make the real leak harder to evaluate later.
How LSL Handles Patching
At Leak and Subsurface Locators, we believe testing comes first. If a simple epoxy patch is appropriate, we may use it after the leak point is identified. That patch can help slow the leak and can also help confirm that the leak point was found. But patching without testing is guessing.
Find it first. Then repair it.
