Shop NowProduct Specifications: PSS PRO Maintenance Kit Dimensions
Downloads: Installation Instructions
As with any rubber or silicone hose below the waterline, the PSS PRO bellows must be inspected regularly for any signs of wear, aging, or chemical deterioration. PYI suggests preventative maintenance with a precautionary replacement recommendation in 8-10 year intervals. During bellows replacement, it is recommended that the o-rings and set screws in the stainless steel rotor also be replaced.

FAQ
What general maintenance should I be considering for a PSS PRO Shaft Seal that is working perfectly well with no apparent issues?
PYI recommends replacing the bellows every 8-10 years with the PSS PRO Shaft Seal. During bellows replacement, it is also recommended that the o-rings and set screws in the stainless steel rotor be replaced and the hose clamps. Under most circumstances, the carbon stator and the stainless steel rotor will not need to be replaced.
Can I re-use my set screws when making an adjustment or removing the PSS Shaft Seal?
No, please be sure never to use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft, and the other is tightened onto the first to lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft, ensuring a secure grip. PYI's PSS Maintenance Kit comes with five new set screws included. So when re-installing the rotor, please use new set screws. If you do not have spare set screws, the set screws in the rotor need to be reversed, so there is an unused cup being compressed onto the shaft.
