GW7904 | Pentair GW7900 SandShark Pool Cleaner Flexible Snap Kit

If you need to replace the bumper, turn the housing/bumper assembly upside down and remove the two flex snaps holding the bumper to the housing, (see Figures 40 & 41). Use a piece of ½ in. (inside diameter) PVC pipe to slide over the flex snap ends to squeeze the flex snaps together so they can be slid out of the housing. Use a pair of pliers to pop the flex snaps off of the bumper.
