How to Fix a Swimming Pool Leak – Complete Guide

How to Fix a Swimming Pool Leak

Once you have established that your pool is leaking, do not fret. Here are the specific steps you need to fix your concrete pool leaks, on their location. It will help you how to fix a swimming pool leak.

Depending on the damage, concrete pool leak repairs can be extensive and costly. After pinpointing the culprit of the leak, you may be able to repair it yourself with a temporary patch.

How to Fix a Swimming Pool Leak?

Concrete pools are made to last decades, and with reasonable care and maintenance, they can. And if you want to know how to fix a swimming pool leak?  However, three significant leaks affect concrete pools.

  • Structural Leaks
  • Fitting Leaks
  • Plumbing Leaks

1. Concrete Pool Structural Leaks

A structural leak is a leak in the structure of the vessel itself. For concrete pools, this most likely means a crack or fissure in the pool shell, which you must repair immediately.

Causes of Structural Leaks

Structural leaks typically occur when there is a crack in the pool’s shell. These structural cracks are often caused by:

  • Poor construction or engineering
  • Ground movement
  • Pressure from groundwater
  • Settling due to shifting soil
  • Freezing and thawing cycles

2. Concrete Pool Fitting Leaks

A fitting of the pool shell is any penetration through the pool shell. Think of things like lights, skimmers, and even jets. And because concrete pools are not watertight, the opportunity for leaks is higher.

Causes of Fitting Leaks

The pool cavity is mainly plumbing, and when a fitting is inserted, builders pack in plaster around it, leaving those areas vulnerable to leaks. For example, leaks are more probable if areas around the railing or tiles are loosely fitted.

3. Concrete Pool Plumbing Leaks

Plumbing in a pool can be fickle. Correct installation is critical because if it moves at all, it can leak. It means that the plumbing needs to be secured during installation. You can rest easy if it’s held down with straps or run to the ground.

Causes of Plumbing Leaks

The movement of the system causes plumbing leaks. Settling in the ground, for example, can cause systems to move, creating a leak in the plumbing. Corrosion is another issue that may cause a swimming pool’s plumbing system to leak.

Identifying a Pool Leak

Identifying a Pool Leak

The concrete pool leak detection process can be pretty transparent if you know what to look for. For example, if you are experiencing any of the following, you are likely to leak:

  • Cracks or gaps in the concrete vessel
  • Settling of the vessel into the ground
  • Displaced or loose tiles
  • Mushy spots or standing water around the pool
  • Needing to add more water than usual
  • Algae forms quickly after a chemical treatment
  • The automatic filler constantly releases water

So how to fix a swimming pool leak? Here is the answer. To repair a leak near the faceplate, jets, or lights, you can likely put silicone around it to secure the water and stop the leak.

  • Plumbing leaks: If you think there is a leak in your plumbing, call a professional. It could involve digging the foundation around the pool and replacing pipes. It would be one of those scarier leaks that will likely cost more to repair.
  • Main drain leaks: Unfortunately, the only option to repair the main drains is to replace them. While you wait for the replacement, you can plug a pipe into the drain and turn it off completely.
  • Skimmer leaks: A temporary fix for a leak in the skimmer is to patch it with silicone. Most cases require a skimmer replacement as a permanent fix.

How to Fix a Pool Leak Underwater?

How to Fix a Leak in a Swimming Pool Skimmer?

The most common leak is separating the plastic skimmer and the concrete pool. It is easily fixed with pool putty. At some point, in-ground concrete pools will develop leaks at the skimmer. So how to Fix a Leak in a Swimming Pool Skimmer?

Over time, the contractions and expansion of the pool and deck will break the seal between the pool wall and skimmer, causing leaks. The most common way to fix a leaky pool skimmer is by applying repair putty.

How to Fix a Leak in a Swimming Pool Skimmer? Once you have located the exact area of the leak along the seam, you first need to remove a piece of underwater pool repair putty from the tube and knead it with your fingers.

Do it several times into the area of the leak. Then smooth out the putty using your fingers and wait for about 24 hours when it should have already changed into a white color, indicating that it has already cured and you can finally turn the pump on.

How to Fix a Pool Leak in Pipes

When are you trying to find out how to fix a swimming pool leak? And you come to know that your pool leaks are coming from the underground plumbing-the large backhoe that comes in and rips up your pool deck.

How to Fix a Pool Leak in Pipes

So how to fix a pool leak in pipes? Whether the leak emerges from a pipe connector below the pool deck or under the skimmer, fixing leaks from underground plumbing is not easy.

  • If the length of your pipe run is concise, or if you find that the entire pipe is already severely damaged, It is best to replace the entire pipe and leave the old pipe in the ground if your pool has a short pool deck apron, which is about 3 to 4 ft in width.
  • You may tunnel under the deck, then cut it and dig. Usually, just a few hours of digging is enough to have the skimmer pipes unearthed. You may also want to dig up enough dirt under the deck to unearth the underside.
  • And use heavy timbers cut to size to hold up the pool deck. Your other option is cutting the pool deck using a concrete saw and then breaking up the deck and digging out some dirt until the leaking pipe, or cracked pipe fitting is finally exposed.
  • Once you have located the leak in your underground plumbing, the next step is to cut out the damaged part and replace it with new if all you need is a simple fitting replacement.
  • Make enough room to connect the new fitting to the pipe with a coupling. If your plumbing needs more complicated repairs, however, you need to devise a diagram to take note of all the fittings and equipment.
  • Either way, the most common way to fix an underground plumbing leak is by replacing lousy glue joints or cracked fittings by cutting out the old ones and gluing the new PVC pipe and fittings.
  • To clean and soften the pipe, use a PVC primer for about 30 seconds before adding copious amounts of fresh PVC glue. Wipe up the glue drips after pushing the pipe deep into the fitting and hold it for around 10 seconds.
  • If you are gluing the 90s and 45s, there is a way to correct the angle when gluing them in place. Glue them in place with a length of PVC pipe inserted into the other side so the fitting faces the exact direction it needs to face.

How to Fix a Leaking Pool Return Jet?

How to Fix a Leaking Pool Return Jet

Here is everything you need to know about how to fix a leaking pool return jet. Below you can find out 5 different methods to fix a leaking pool return jet.

Damaged Return Inlet

No pool is all of one piece – pumps and motors circulate water through – debris-catching filters and cleaning feeders, pushing the water in and out of the pool’s vacuum ports and returns, also called “jets.”

Though it takes a whole team of components to keep your pool trucking, the points at which various parts meet are the most susceptible to leaks. To patch up leaks, turn to another knockout combo – two-part “pool putty” epoxy.

  1. Put on a pair of rubber gloves and fill a dropper – like a tester bottle, the type that comes with pool testing kits with red food coloring. The red color contrasts with blue chlorine, helping you identify the leak’s specific position.
  2. Position yourself at the pool’s edge to reach the leaky jet by lying safely on your stomach.
  3. Brush the area around the jet thoroughly with a wire brush or stiff-bristled toothbrush to remove algae and debris. That promotes surface adhesion when you use pool putty and enables how to fix a swimming pool leak.
  4. Squeeze a drop of red food coloring near the leaky jet around the seams of the wall fittings. You will see a red, flowing cloud at the surface of the leak.
  5. Mix the two parts of the epoxy, the resin and hardener, together. Using equal parts of each- about a marble-sized amount- does the trick for most jet leaks.
  6. Roll the putty into a long, snakelike shape between your gloved palms. Press the roll of putty onto the leak, using your fingers to smooth it into the seam between the jet’s fittings and the pool wall. That’s how to fix a leaking pool return jet?
  7. Perform another test with the red food coloring to check your results, and apply more putty as needed. Allow the putty to dry completely — specific drying times may vary depending on the brand of epoxy.
