About to be a fun summer!!! The pump is an extra addition that is amazing to keep the fun going. You will need to drill a bigger hole on top and we drilled a hole on the side to re route the pipe into the middle of the water table. We used electrical tape to secure it (the black band). This way the pipe doesn’t interfere with the toys on the side. The pump is rechargeable and last for several hours of run time. Also adds a fountain sounding ambiance for the parents to enjoy :) LTKFamily LTKSummerEdit LTKKids
