Reverse osmosis systems normally send reject water to the drain. Learn how refill timing, an RO feed-valve test, and the whole-house meter can separate normal operation from a hidden leak.
Bubbles or loss of prime only with a suction cleaner connected do not automatically prove a buried pool line leak. Learn the isolation sequence that separates hose, equipment, and vacuum-line problems.
Learn how dye observations, water-level patterns and controlled plumbing tests help distinguish a pool light niche leak from a conduit or nearby shell leak.
Learn how water-softener regeneration can mimic intermittent leakage on the meter and how bypass, timing and controlled observations separate the patterns.
Use meter observations, house and irrigation shutoffs, controller timing and yard evidence to separate an irrigation leak from a hidden house water leak.
If your spa water level drops when the spillway is off, learn how check-valve behavior, shell leaks and plumbing tests help separate the possible causes.
A high bill and moving meter do not automatically mean a buried pipe is leaking. Use a controlled isolation sequence to separate toilets from concealed piping.
A pump that repeatedly loses prime may point to an air leak, low water, equipment issue, or a leaking suction line. Diagnose the pattern before digging.
A pool that drops and then stabilizes offers a useful elevation clue. Learn how to interpret it without assuming the first fitting at that height is the source.
When the meter stops after the house shutoff closes, the result narrows the leak to plumbing downstream of that valve—but more isolation is still needed.
