Although very little maintenance is required, the pss bellow component must be inspected on a regular basis for any sign of wear, aging or chemical deterioration, as with any rubber Hose below waterline. The pss bellow should be replaced six year intervals as preventative maintenance. During bellows replacement it is recommended the offerings & set screws in the stainless steel rotor also be replaced.
