When it comes to keeping your swimming pool clean and safe, your skimmer plays a crucial role. It's responsible for drawing in water from the surface of your pool, capturing debris like leaves, bugs, and dirt before they sink to the bottom. Over time, however, your skimmer may begin to wear down or crack, leading to water leaks, poor suction, or inefficient filtering. That's where skimmer replacement becomes not just necessary but essential for your pool's longevity and performance.

Whether you're a DIY pool owner or considering hiring a professional, understanding the skimmer replacement process will help you make informed decisions and maintain your pool effectively year-round.

What is a Pool Skimmer?

A pool skimmer is a small, built-in device located on the side of your pool. As water circulates through your pool’s filtration system, the skimmer draws water from the surface, capturing floating debris before it reaches the pool bottom.

There are generally two types of skimmers:

• In-ground pool skimmers – Built into the side of the pool structure

• Above-ground pool skimmers – Usually hang over the edge of the pool and are removable

Skimmers often contain a basket to trap large debris and a weir (a floating flap) that helps regulate water flow.

Signs You Need a Skimmer Replacement

Before jumping into the skimmer replacement process, it's important to recognize when it's time to replace it. Here are common signs that your pool skimmer may be failing:

Cracks or Leaks

One of the most common problems with old skimmers is cracking. Skimmers are usually made of plastic, which can become brittle over time due to sun exposure and water chemicals. If you notice leaking around the skimmer area or suspect a water level drop not caused by evaporation, a cracked skimmer could be the culprit.

Poor Water Circulation

If the water isn’t moving properly or the suction near the skimmer is weak, it may be clogged or broken. Poor water circulation can lead to algae growth, dirty water, and higher chemical usage.

Broken Weir or Skimmer Lid

These components may seem small, but they are critical to the function of the skimmer. If the weir gets stuck or the lid is broken, it can impact the efficiency of your pool's cleaning system.

Age and Wear

If your pool is more than 10-15 years old and still has the original skimmer, it may simply be time for an upgrade. Like any piece of equipment, skimmers have a lifespan.

Benefits of Replacing a Pool Skimmer

Replacing a faulty skimmer can bring multiple benefits, including:

• Better water filtration: A new skimmer ensures that debris is properly removed, improving water clarity and hygiene.

• Leak prevention: Fixing a damaged skimmer prevents further structural damage from water leaks.

• Lower maintenance costs: Efficient skimmers reduce the load on your filtration system, saving you money on repairs and energy bills.

• Improved pool performance: Proper water flow and circulation lead to balanced water chemistry and a more enjoyable swimming experience.

DIY vs. Professional Skimmer Replacement

Doing It Yourself

If you’re experienced with pool maintenance or construction, a DIY skimmer replacement might be possible. However, it requires:

• Cutting through concrete (in in-ground pools)

• Plumbing and sealing knowledge

• The right tools and replacement parts

Replacing a skimmer on an above-ground pool is significantly easier than on an in-ground pool, which involves digging and concrete removal.

Hiring a Professional

In most cases, hiring a certified pool technician is the safest and most efficient option. They can:

• Accurately identify the source of the problem

• Perform a leak test

• Remove and replace the skimmer with precision

• Ensure that plumbing and seals are correctly installed

While more costly upfront, professional replacement often saves money in the long run by avoiding potential mistakes and further damage.

Skimmer Replacement Process (In-Ground Pools)

Here's an overview of the steps typically involved in replacing an in-ground pool skimmer:

Step 1: Drain the Pool Below Skimmer Level

The water needs to be drained to just below the skimmer to provide access. This also prevents further leakage during the replacement process.

Step 2: Cut and Remove the Damaged Skimmer

Using a saw or jackhammer, the concrete or deck area surrounding the skimmer is carefully removed. The old skimmer is then detached from the plumbing lines and pulled out.

Step 3: Install New Skimmer

The new skimmer is fitted and connected to the pool plumbing. Care is taken to ensure the alignment matches the original skimmer.

Step 4: Seal and Secure

The area around the new skimmer is sealed with waterproof material to prevent leaks. Plumbing joints are tested for leaks as well.

Step 5: Re-pour Concrete or Patch Decking

After the new skimmer is secured, the deck area is patched or re-poured to match the existing surface.

Cost of Skimmer Replacement

The cost of skimmer replacement can vary depending on pool type, skimmer model, and whether you're hiring a professional.

• DIY replacement (above-ground): $50 – $150 (for the part only)

• Professional replacement (in-ground): $800 – $2,000+

Labor and concrete removal are the biggest cost factors in in-ground pool skimmer replacements.

How to Extend the Life of Your Pool Skimmer

To reduce the frequency of replacements, here are some tips to keep your skimmer in good condition:

Regular Cleaning

Empty the skimmer basket at least once or twice a week to ensure optimal water flow and prevent clogs.

Check for Damage

Routinely inspect the skimmer lid, weir, and housing for signs of wear or cracks. Early detection helps prevent bigger problems.

Winterizing

If you live in an area with cold winters, make sure to properly winterize your pool skimmer by draining water and plugging lines to prevent freezing damage.

Use Skimmer Socks

These mesh filters sit inside the skimmer basket and catch fine debris like hair and bugs, preventing clogs and reducing stress on the pump and filter.

Conclusion

Your pool skimmer may not be the flashiest part of your pool system, but it's certainly one of the most vital. From trapping debris to ensuring smooth water circulation, it plays a major role in maintaining water clarity and hygiene. Recognizing the signs of a failing skimmer and replacing it promptly can save you from bigger headaches like water leaks and equipment damage.
