Pool Leak FAQs

Leaving a pool leak unaddressed can result in lasting damage to both the pool and its surrounding decking. As water seeps out, it can erode the soil, creating voids beneath the pool or deck and leading to deterioration of the reinforcing bar that supports the structure. Detecting and repairing leaks early can help you avoid expensive and extensive repairs later on.

Pump Damage

If a leak is left untreated and the pool’s water level falls below the skimmer throat, the pump may run dry, leading to overheating and potential damage to the pump.

Increased Cost of Water & Chemicals

When dealing with a pool leak, you know draining it isn’t an option due to the risk of structural damage. You also want to keep the water level above the skimmer to prevent pump issues. As a result, you’re constantly refilling the pool to maintain the correct water level, which means using extra water and additional chemicals or salt to keep the system balanced. The expenses for water and treatments can quickly add up, making timely leak repair a smart and cost-effective solution. Contact Bullseye Leak Detection in Stockton to schedule an appointment for pool and spa leak detection and repair.

In heavily saturated soil, a pool can start to "float" if there isn’t enough water inside to balance the pressure exerted by the surrounding ground.

If the soil around a fiberglass pool becomes overly saturated, the sides of the pool may begin to bend or buckle, leading to significant and costly damage. While minor damage might be fixable, severe warping often necessitates a full pool replacement.

For this reason, we strongly advise against fully draining your pool under most circumstances.

Your pool may have a leak if you notice these signs:

  1. Water level drop
  2. Excessive chemical use
  3. Cracks or loose tiles
  4. Wet spots or soft soil
  5. Increased water bills

If you suspect that your pool has a leak, you should contact the experts at Bullseye Leak Detection in Stockton. We have a team of professionals that can identify and fix swimming pool leaks fast.


Wondering if your pool might be leaking? If you’ve seen an unexpected spike in your water bill or noticed soggy spots in your lawn, there could be a leak in the pipes or pool structure. The most effective way to confirm a leak is to schedule a pool leak inspection in Stockton.

Before contacting a technician, you can try some simple DIY leak tests. For example, the bucket test is an easy method to determine if water loss is due to a leak instead of just evaporation. If your test results suggest a leak in your pool or spa, don’t hesitate to reach out to us.

Our technicians are experienced in testing all types of pool systems, from basic single-pump setups to complex, multi-pump backyard water features. Pool systems come in different sizes, materials, and configurations, so testing costs can vary. Feel free to call or email our office for a quote.

By pressure testing each line individually, we can pinpoint the exact location of a leak. Our inspections cover the pool structure both above and below the surface using scuba equipment when needed. We also use non-toxic dye to distinguish whether a gap or crack is merely cosmetic or an actual leak source. Our leak detection services come with a 30-day guarantee—if another leak is found, we’ll return at no extra charge to locate the new issue!

salt or chlorine

All pool and spa systems must be treated to prevent bacteria and algae growth.


In most cases, treatment involves adding liquid or tablet chlorine. Bromine systems function in a similar way. Saltwater systems also provide chlorine treatment, but they do so through a different delivery method. Using electrolysis, salt is broken down into its basic components: chlorine and sodium.

Many pool owners appreciate the feel of water treated with salt and conditioner. However, when a saltwater pool or spa develops a leak, it loses both salt and conditioner. As fresh water is added to maintain the pool’s level, the system becomes diluted, requiring frequent salt additions throughout the year.

In bromine and chlorine systems, chemicals need to be continuously added to compensate for water loss. If you find yourself using large amounts of salt or chemicals, it could be a clear sign of a leak.

A standard pool has a suction line and a return line.


The first line draws water from the pool, while the second line pushes water back into it. A leak can develop in these lines anywhere between the pool port or skimmer and the pump.

If you have a spa, it introduces an extra suction and return line, and features like fountains, disappearing edges, and waterfalls also add complexity. When scheduling your leak detection appointment, we ask for a detailed inventory of all features in your system. This helps us provide accurate pricing and allocate the right amount of time for testing.

pool structures

Pool surfaces can be Pebble Tec, plaster, fiberglass, or a vinyl liner. Each surface ages and shows signs of wear differently.


Different pool surfaces age and show wear in distinct ways. For example, a leaking crack in a Pebble Tec pool might go unnoticed for months, while a visible crack in a plaster pool might be purely cosmetic and not actually causing any leaks.

Our technicians conduct a comprehensive inspection of the entire structure, examining pool walls, floors, steps, benches, lights, tiles, ports, and skimmers.

If a structural leak is detected, we apply a temporary patch using a two-part marine-grade epoxy. These temporary patches help us isolate the source of the leak and stop immediate water loss but are not intended as a permanent or guaranteed fix.
