Pressure testing and dye detection for pool plumbing leaks in Lakewood’s residential pools. Call (562) 358-3931 for a detection visit.
Lakewood's original Lakewood Park Corporation homes from 1950 to 1953 were not built with pools, but moderate pool prevalence developed across the city's residential grid in the decades following the original build. Many Lakewood homes have pools added between the late 1950s and the 1980s, which puts much of the city's pool plumbing stock at 40 to 65 years old. The plumbing systems in pools from this era, including galvanized fittings in the earliest pools, PVC pipe and ABS plastic fittings from the 1970s and 1980s, and aging skimmer bodies where they meet the concrete or gunite shell, are now showing the deterioration that produces slow, persistent leaks.
A pool losing water faster than evaporation accounts for is wasting water, adding chemical costs as dilution continually changes the water balance, and potentially damaging the pool structure and surrounding soil if a leak in a buried supply or return line is saturating the ground near the pool foundation. Pool leak detection requires systematic pressure testing of the plumbing system lines from the equipment pad and targeted dye testing at fitting connections and skimmer bodies to isolate whether the leak is in the plumbing, at a fitting, or at the pool shell. We provide written detection findings and a repair estimate before any repair work begins.
A pool losing more than a quarter-inch of water per day beyond evaporation has a measurable leak. The bucket test (a partially submerged bucket compared to the pool water level over 24 hours) is the standard way to separate evaporation loss from actual water loss. If the pool drops measurably more than the bucket over the same period with the pump running, a leak is present somewhere in the system.
A pool with an automatic fill valve that runs frequently or for extended periods to maintain the water level is compensating for water loss. If the auto-fill was not previously running this often and no other changes to the pool have occurred, the fill frequency increase indicates a new or worsening leak. The auto-fill can mask how much water the pool is actually losing, making the bucket test more difficult to interpret.
Persistently wet soil around the pool equipment pad, along the buried supply and return line path to the pool, or near the skimmer and return fittings can indicate a leak in the plumbing or at the shell connection points. In Lakewood's residential lots, the equipment pad is typically at the rear of the property near the pool, and wet soil in dry weather directly adjacent to the pad or along the buried line path is a reliable indicator of an underground plumbing leak.
A pool that requires more frequent chemical additions than previously to maintain proper pH, alkalinity, and sanitizer levels may be losing water through a slow leak that is being replaced by fresh water through the auto-fill. Fresh water dilutes the chemical balance and requires more frequent treatment. If chemical consumption has increased without an obvious explanation, a leak assessment is warranted alongside a chemical service check.
Pool leak detection begins with a visual inspection of the equipment pad, plumbing lines, and fitting connections visible above grade, followed by a pressure test of the suction and return plumbing lines. Pressure testing isolates the plumbing system from the pool shell and confirms whether the leak is in the buried plumbing runs or at the pool itself. If the plumbing pressure holds, the leak is in the shell, at a fitting where the plumbing connects to the shell, or at the skimmer body. If the plumbing does not hold pressure, the leak is in a buried supply or return line.
For fittings and skimmer connections that do not show a pressure drop but are suspected leak points, dye testing places a small amount of colored dye near each suspected fitting or crack while the pump is off and the water is still. An active leak draws the dye toward the leak point, making the location visible in the water. This method identifies fitting connection leaks, hairline cracks in skimmer bodies, and shell cracks at stress points. After the leak location is confirmed, we provide a written repair estimate covering the repair method and any excavation required to access buried plumbing.
Pool leak detection service in Lakewood costs $250 to $500 for a complete pressure test and dye inspection visit. Repair costs depend on the leak location: accessible fitting repairs and skimmer connections are typically $200 to $600 and are often completed on the same visit as detection. Buried plumbing line leaks requiring excavation to access typically cost $800 to $3,500 depending on pipe depth and run length. Written estimates covering repair scope and any excavation are provided after the leak location is confirmed.
The bucket test is the standard homeowner self-check. Fill a 5-gallon bucket to the same water level as the pool, place it on a pool step so it is partially submerged, and mark both the bucket water level and the pool water level. After 24 hours with the pump running normally, compare the two. If the pool level dropped more than the bucket level, the pool is losing water beyond normal evaporation. A pool losing more than a quarter-inch per day beyond evaporation has a measurable leak that warrants professional detection.
In Lakewood's pools from the 1960s, 1970s, and 1980s, the most common leak locations are: fitting connections at the return jets and skimmer fittings where the pool plumbing connects to the shell; the main drain connection at the pool floor; the plumbing suction and return lines between the pool and the equipment pad; and the skimmer itself, which can crack where the ABS plastic body meets the concrete shell. Shell cracks in older gunite pools are less common but do occur at structural stress points.
Pool leak detection in Lakewood typically costs $250 to $500 for a full detection visit including pressure testing of the plumbing lines and dye testing of fittings and suspect areas. If the leak is in a plumbing line that requires excavation to access, excavation and repair costs are additional and are provided in a written estimate after the leak location is confirmed. If the leak is at a fitting or skimmer connection that is accessible without excavation, repair is often completed on the same visit.
Minor pool plumbing repairs at fittings and connections typically do not require a permit. More significant pool plumbing work, including replacement of buried supply or return lines, may require a permit from the City of Lakewood Building and Safety Division depending on the scope. We identify the permit requirement in the written estimate before work begins. Pool shell structural repair typically requires a separate building permit and falls outside standard plumbing scope.
