when I started my pond this summer, I had one of my pump hoses come loose but luckily my wife spotted it early and we only lost about 25% of the water. I have two Maxflo pumps and last weekend, I placed it on a cinderblock which gave it 8 inches water which can't be pumped out should this happens again. Will having the pump elevated cause problems in cleaning the pond properly? Are there other ideas to prevent another potential catastrophic event?
