sump pumps

Hi, Dave. Some sump pumps do not have floats. Mine has a tube that goes into the sump. Rising water seals the tube then starts to build pressure in it. The rising pressure activates the switch. Neat system but the tube has gotten clogged with moss from the sump once in 20 years.

Good luck
