Low Suction level pumps are commonly know as 'Puddle pumps'. They are a specialist type of submersible pump that is optimised to drain water to extremely low levels, commonly down to just a couple of millimeters. They are designed for a lighter workload than standard sump submersibles and suted to this specific application.
The pumps shown in this category are purposely designed for to operate down to very low suction levels and are great at removing water from cellars, driveways, flat roofs, showers, tennis courts are many more similar applications. They will leave the water level low enough to simply brush it away.
The 'Simmer' drains to the lowest level (manual mode) but doesn't drain a low with the automatic sensor option added, where as the popular 'PUK EGO' is a great general use option and drains almost as low and is automaticaly controlled as standard.
