The drain plug seal for Badu Bettar pumps is a small O-ring measuring 11×2.5 mm that seals the screw plug used for draining water from the pump body in winter.
A damaged or hardened seal causes water to drip at the plug even when it is in the closed position, leading to water loss and a reduction in the pump’s suction capacity.
Replacement is quick and does not require dismantling the pump — simply unscrew the plug, replace the O-ring and retighten the plug.
The material withstands chlorinated water and temperature fluctuations from summer operation to winter storage.
We recommend replacement every two years or whenever dripping appears when the plug is tightened.
