Aquatonics R38013B Replacement Floating Skimmer Weir for Pentair Admiral/Aladdin B-38 — Heavy-Duty Chemical-Resistant Plastic

Aquatonics R38013B is a heavy‑duty floating skimmer weir designed to fit Pentair Admiral and Aladdin B‑38 skimmer baskets, keeping surface debris out of your inground pool filtration system.

Keep your pool cleaner with a replacement floating weir built to the same fit and function as OEM parts. This Aquatonics R38013B skimmer basket floating weir uses a tab‑and‑notch mounting pattern for secure placement in Pentair Admiral, Aladdin B‑38, and compatible 850012‑S‑10 housings. Constructed from durable plastic formulated to resist pool chemicals and seasonal wear, it helps the skimmer capture leaves, insects, and other floating debris before they reach the pump.

How does this floating weir improve surface skimming?

The Aquatonics R38013B rides at the waterline to create a consistent laminar flow into the skimmer when your pump runs. That movement forms a small vortex that funnels floating debris directly into the basket rather than letting it drift across the pool surface. The result is fewer manual skims and reduced strain on the filtration system.

• Top edge floats at waterline for continuous surface draw
• Vortex suction directs leaves and debris into the basket
• Works with skimmer socks and basket inserts for extra filtration

Will this fit my Pentair Admiral or Aladdin B‑38 skimmer?

This replacement is engineered specifically to match the tab‑and‑notch geometry used by Pentair Admiral and Aladdin B‑38 models, plus commonly compatible 850012‑S‑10 assemblies. If your skimmer uses the same mounting pattern it will seat securely and maintain proper flow. Check your existing weir’s shape and tabs to confirm compatibility before ordering.

• Designed for Pentair Admiral and Aladdin B‑38 skimmers
• Tab‑and‑notch fit for stable placement
• Compatible with many 850012‑S‑10 style setups

How durable is the Aquatonics R38013B in pool conditions?

The weir is molded from a robust plastic blend formulated to tolerate chlorine, salt, and seasonal temperature shifts without warping or cracking. Its heavy‑duty construction holds up under repeated pump cycles and resists damage from heavier debris loads. Routine inspection and cleaning will maximize service life, but the part is built for long‑term performance.

• Chemical‑resistant plastic for pool environments
• Engineered to withstand heavy debris and frequent use
• Designed to maintain shape and function across seasons

How do I install and maintain this replacement weir?

Installation is straightforward: remove the old weir, align the tabs with the skimmer notches, and press into place until it clicks. Clean the skimmer basket regularly and remove trapped debris to prevent clogging and keep the weir operating smoothly. If the weir becomes brittle, cracked, or fails to seat properly, replace it to restore effective skimming.

• Quick tab‑and‑notch installation—no tools required
• Inspect and empty skimmer basket frequently
• Replace when warped, cracked, or unable to seat securely

Who is this for: Pool owners and maintenance professionals using Pentair Admiral or Aladdin B‑38 style skimmers who want an affordable, OEM‑compatible replacement weir that improves surface cleanup and protects the filtration system. Ideal for inground pools that contend with leaves, pine needles, insects, and frequent surface debris and for anyone looking to reduce manual skimming and pump maintenance.
