Restore Proper Air Relief and Pressure Stability in Triton II Filters

Air trapped inside a pool filter tank can cause inaccurate pressure readings, reduced filtration efficiency, and inconsistent system performance. The Swimables Pentair® Style Triton II Air Bleeder Tee Assembly (SW-26-689) is a direct-replacement component designed to restore proper air relief function in Pentair Triton II sand filter systems.

This assembly replaces Pentair OEM part number 154689 and installs directly into compatible Triton II filters without modification. When the original tee becomes cracked, brittle, or partially blocked, air can accumulate inside the filter tank—leading to pressure spikes, uneven flow, or difficulty priming the system. Replacing the air bleeder tee helps return the filter to stable, predictable operation.

This is a pool-specific filter component, not a general plumbing fitting.

What the Air Bleeder Tee Assembly Does

The air bleeder system allows trapped air to escape from the top of the filter tank during startup and operation. The tee assembly plays a key role by directing air to the manual or automatic air relief valve.

A properly functioning air bleeder tee helps:

• Release trapped air from the filter tank

• Stabilize pressure gauge readings

• Improve filtration efficiency

• Prevent air pockets from disrupting flow

• Protect internal filter components

When this part fails, air may remain trapped inside the tank, causing erratic pressure behavior and reduced system performance.

For related components, this part is commonly serviced alongside items in the Pool Filter Parts Collection.

Direct Replacement for Pentair Triton II Filters

The Swimables SW-26-689 is engineered as a Pentair-style replacement for OEM part 154689 and is designed specifically for Triton II sand filter systems.

Key compatibility points:

• Replaces Pentair part number 154689

• Designed for Pentair Triton II sand filters

• Correct port orientation and sizing

• Installs without modification

Using the correct air bleeder tee is critical—improper fittings can leak, restrict airflow, or fail prematurely under filter pressure.

Common Signs the Air Bleeder Tee Needs Replacement

This component is often overlooked until noticeable system issues appear. Replace the air bleeder tee assembly if you experience:

• Air trapped in the filter tank after startup

• Pressure gauge fluctuating or reading incorrectly

• Visible cracks or brittleness in the tee

• Air leaks around the air relief assembly

• Difficulty bleeding air from the filter

These symptoms are especially common on older Triton II filters where plastic components have been exposed to years of pressure, heat, and chemical exposure.

If pressure issues persist, related components in the Pool Filters Collection should also be inspected.

Built for Pool Filter Operating Conditions

Unlike generic plumbing tees, the Swimables air bleeder tee is manufactured for pressurized pool filter environments.

Design considerations include:

• Resistance to chlorinated and saltwater conditions

• Ability to withstand continuous internal pressure

• Dimensional accuracy for leak-free installation

• Material durability under outdoor heat and UV exposure

This ensures consistent performance and long service life when installed in Triton II filters.

Why Proper Air Relief Matters

Air trapped in a filter tank reduces effective filtration area and disrupts water flow. Over time, this can lead to:

• Reduced filtration efficiency

• Inconsistent circulation

• Increased strain on the pump

• Misleading pressure diagnostics

• Premature wear on filter internals

Replacing a worn air bleeder tee helps maintain balanced hydraulics and accurate system monitoring.

For system-wide efficiency, air relief components work best when paired with proper circulation from items in the Pool Pumps Collection.

Simple Installation During Routine Service

Replacing the Swimables SW-26-689 air bleeder tee assembly is typically performed during filter service or maintenance.

General Installation Steps:

1. Turn off the pool pump

2. Relieve pressure from the filter tank

3. Remove the existing air bleeder tee

4. Install the new SW-26-689 tee assembly

5. Reattach air relief components

6. Restart the system and bleed air

Professional installation is recommended to ensure proper sealing and pressure safety.

Ideal for Preventative Maintenance

Because air bleeder components are exposed to pressure and chemicals, they are commonly replaced during:

• Sand changes

• Multiport valve service

• Pressure gauge replacement

• Filter tank inspections

Replacing the air bleeder tee proactively can prevent leaks and performance issues later in the season.

This component is often serviced alongside items found in the Pool Maintenance Tools Collection.

Compatible Pool Applications

The Swimables Pentair-style Triton II Air Bleeder Tee Assembly is suitable for:

• Residential in-ground pools

• Commercial pool systems using Triton II filters

• Chlorine pools

• Saltwater pools

Always verify filter model compatibility before ordering.
