The Pentair T26 is the OEM replacement brass autofill float valve with a 3/8″ MPT connection, designed for pools and spas equipped with an autofill or automatic water leveler system.
The float valve opens to admit fresh water when the pool surface drops below the set level and closes once the correct level is restored preventing overfill and protecting equipment that depends on consistent water depth to operate correctly. The brass body construction provides durability in chemically treated water environments.

Poolaroo Pro Tip
Before ordering, verify the connection size and thread type on your existing autofill assembly. The T26 uses a 3/8″ MPT (male pipe thread) connection confirm this matches the female fitting on your water supply line or autofill housing. Check the part number stamped or cast on your original valve to ensure an exact match before adding to cart.
