The white ones that I have for the pier are brittle. A couple cracked when I was pushing the pier into the water, and I think at least one more that is under the pier is taking on water.

On another note, is there anything that can be used to monitor (on a daily/weekly/monthly basis) energy usage for a 3/4 to 1.5 hp 120v motor? Nothing fancy or really expensive, basically something that could be plugged into an outlet and the motor plugged into that monitor is what I'm looking for.
