How to replace a pool skimmer lid

Introduction

Is your pool skimmer lid cracked, loose, or missing entirely? It might seem like a small part, but it plays a big role in safety and functionality. If you’re wondering how to replace a pool skimmer lid, this step-by-step guide will walk you through the process with ease—even if you’ve never done pool maintenance before.

Whether the lid is damaged by UV rays, warped from weather, or simply worn out, replacing it ensures your pool stays safe and running properly.

Why Replacing the Skimmer Lid Matters

The skimmer lid covers the opening to the skimmer basket, which is responsible for pulling in leaves, debris, and bugs from your pool’s surface. A secure lid ensures:

  • Safety: Prevents tripping hazards or foot injuries
  • Proper skimmer function: Keeps large debris out of the plumbing system
  • Equipment protection: Stops pool toys, branches, or other objects from falling in
  • Appearance: Keeps your pool deck looking neat and finished

Cracked or missing lids pose safety risks and can lead to expensive repairs if water flow is compromised.

Step-by-Step Guide to Replacing a Pool Skimmer Lid

Step 1: Identify Your Skimmer Type and Size

Before buying a replacement, identify the brand and model of your skimmer. Most pool skimmers are round, but some are rectangular.

Here’s how to find the right replacement:

  • Check the underside of the old lid for a manufacturer name (e.g., Hayward, Pentair)
  • Measure the diameter of the skimmer opening and the lid
  • Take note of any unique locking mechanisms (twist-lock, snap-on, etc.)

Tip: Bring your old lid to the pool store or match it online using part numbers.

Step 2: Purchase a Compatible Skimmer Lid

Buy a new lid that matches:

  • Size
  • Shape
  • Locking style

Make sure it’s UV-resistant and durable, as cheap plastic lids can warp or crack quickly under sunlight.

Optional: Consider buying a lid with textured anti-slip surface for added safety around the pool deck.

Step 3: Remove the Old Skimmer Lid

This part is easy but important—remove the old lid carefully so you don’t damage the surrounding skimmer ring.

  • If the lid is broken, use a flathead screwdriver to gently lift under one side.
  • For twist-lock lids, rotate counterclockwise until it releases.
  • If stuck due to swelling or age, pour warm water over it to soften the plastic and try again gently.

Caution: Avoid using excessive force. Damaging the skimmer housing can be expensive to fix.

Step 4: Inspect the Skimmer Ring and Opening

With the lid removed, take a moment to check:

  • The skimmer ring (the plastic collar the lid sits on) for cracks or wear
  • Debris inside the skimmer basket—go ahead and clean it out while it’s open
  • Fit alignment between the ring and pool deck

If the ring is damaged, it may need replacing too (but this usually requires professional help).

Step 5: Install the New Skimmer Lid

Now place the new lid securely onto the skimmer opening:

  • For drop-in lids, center it evenly on the ring and press it down until flush
  • For twist-lock lids, align the notches and turn clockwise to lock it into place
  • Make sure it’s level with the pool deck and doesn’t rock or shift

Test the fit: Step lightly on the lid with one foot to ensure it holds firm. It should not wiggle or lift at all.

Step 6: Clean Around the Skimmer Lid Area

Once the new lid is in place:

  • Sweep or rinse the area to remove dust, leaves, and debris
  • Check that no gaps exist between the lid and deck where someone could stub a toe

If needed, you can add deck sealant around the skimmer ring for a cleaner, more secure finish.

Common Mistakes to Avoid

1. Buying the Wrong Lid Size
Eyeballing it doesn’t work—wrong-sized lids can fall in or sit unevenly.

Solution: Always measure and check the part number or brand before purchase.

2. Forcing the Lid On or Off
Using too much pressure can crack the lid or damage the skimmer housing.

Solution: Gently wiggle, soak, or twist the lid as needed—never pry forcefully.

3. Ignoring Cracks in the Skimmer Ring
A damaged ring can compromise lid security and pose a hazard.

Solution: Replace the skimmer ring if it’s cracked or warped.

4. Leaving the Skimmer Lid Off
This creates a dangerous opening on your pool deck.

Solution: Replace broken lids immediately—even a temporary cover is better than nothing.

5. Using Non-Pool Products
Some DIYers try to use buckets or patio covers as makeshift lids.

Solution: Always use pool-rated skimmer lids designed for weight, UV exposure, and weather.

Extra Tips & Pool Hacks

  • Keep a spare lid on hand during the summer months in case one cracks.
  • Label your skimmer lid size and brand somewhere safe so reordering is quick and easy.
  • For a neater look, consider color-matching your lid to your pool deck or coping stones.
  • Use anti-slip stickers if your skimmer lid is in a high-foot-traffic area around the pool.
