Lowe's Item# 248380
Our 130 â€“ 170 GPH magnetic drive pump with Low Water Shut-off is specifically designed for small and medium fountains. This New Technology pump shuts off when the water level becomes too low and turns back on when the water resumes to normal level. This fountain pump has a maximum pumping height of 4.1'
That's a good thing! When your fountain is out of water, think of all the energy you will save. Not to mention it will help your pump to last longer.
