FL13709 Adaptor Coupling for 5600, 9000 and 9100

The FL13709 adaptor coupling is the genuine Pentair Fleck fitting that connects the control valve body to the bypass or plumbing adaptor on Fleck 5600, 9000 and 9100 series valves. WrekinWater stocks this replacement coupling for customers dealing with leaks or a loose connection at the base of their Fleck control valve.

Technical specifications

Symptoms that mean you need this part

• Water is leaking or weeping from the joint between the valve and the bypass fitting
• The coupling is visibly cracked or has failed at the retaining clip
• The control valve feels loose or rocks on the bypass adaptor
• Drips appear at the base of the valve both in service and during regeneration

Why it fails / why it matters

The adaptor coupling forms the sealed connection between the Fleck control valve body and the bypass or plumbing adaptor beneath it, held together with a retaining clip and O-ring seal. Years of mains pressure cycling, temperature changes and general age can crack the plastic coupling or wear its sealing faces, breaking the joint's seal and causing leaks or a loose fit.

4. Withdraw the old coupling and fit new O-ring seals

6. Restore the water supply and check the joint for leaks under pressure
