| I am running two WAVE pumps on my big pond and a 1/15 hp WAVE on my ring tank. The pumps are all very quiet. The poor pump on my nexus has been run dry twice....both times from me leaving the stopper pipe in the center of the nexus after cleaning. Once it ran dry for 24 hours, the second time it was more like 2 days. The pump was not damaged by either episode. The only negitive about WAVE pumps is the impellers are easily clogged by even the smallest bit of debris (crushed leaves, etc). I accidently overflowed kaldnes into the outlet of the nexus once and the sequence pump (it was too big and was replaced with a smaller WAVE pump) sucked it all up and pushed it right into the pond. The same thing happened later with the wave and the pump clogged up immediatly. The K1 jammed tightly into the impeller fins and it was quite a task to get it cleaned out. |
