Pentair T26 Brass 3/8″ MPT Autofill Float Valve
The Pentair T26 is a brass autofill float valve designed for automatic water-level control in pools and spas. It replaces or upgrades the float-valve assembly in autofill canisters, helping maintain proper water level without manual topping up.
Key Features
- 3/8″ male-pipe-thread (MPT) inlet — compatible with standard autofill canisters and plumbing fittings.
- Durable brass body — resistant to corrosion from pool chemicals and weather exposure for long-term reliability.
- Self-adjusting float mechanism — automatically stops water flow once the water level reaches the preset height, preventing overflow.
- Simple replacement or upgrade option for existing autofill systems — installs directly with minimal plumbing or mechanical changes.

When & Why to Use T26
Use the T26 float valve when you want to automate water-level maintenance — ideal if the pool water drops due to splashout, evaporation, or backwash procedures. It helps protect pool equipment (pumps, heaters, skimmers) from running low on water and reduces the need for frequent manual water top-offs.
Installation & Maintenance Tips
- Shut off the water supply before installation to avoid leaks.
- Ensure the MPT connection threads are clean and properly sealed (use thread sealant or plumber’s tape if needed for a leak-free fit).
- Adjust the float height per instructions so the water level lands at the desired point after fill.
- Test the valve by triggering a refill after water loss (e.g. after backwash or splashout) — confirm that it shuts off correctly when water reaches the set level.
- Periodically rinse and inspect the valve for mineral buildup or corrosion — replace if the float becomes stuck or leaks develop.
