Yes, absolutely.
A cheap pool leak test can miss the real problem if the person does not take the time to evaluate the whole pool. A leak can be in the skimmer, light, fittings, drain, shell, equipment, return line, suction line, spa line, or underground plumbing. If someone only checks one or two obvious areas, they can miss the actual leak.
Sometimes the wrong test gives the customer false confidence. The pool keeps losing water, but the customer thinks it was already checked. Then they waste more money on water, chemicals, service visits, and repairs that do not solve the problem.
The Bigger Risk
The bigger risk is when a bad leak test leads to the wrong repair. Cutting concrete in the wrong area, patching the wrong spot, replacing parts that were not leaking, or ignoring a plumbing issue can cost far more than proper leak detection would have cost.
Pool leak detection is not about being fancy. It is about being thorough. At LSL, we follow a process so we are not just guessing at the easiest or cheapest answer.
