Bottom Drain - Sump Type (110mm)

Bottom drains today are used in conjunction normally with a gravity fed filter systems, but more people are using them with pump fed systems. However, which ever way you decide,, either way is far better than not having a drain installed at all. A chamber of filter brushes holding back debris in a pumped system cannot compare to a bottom drain working in conjunction with a vortex settlement.Ideally suited for draining heaver particles to waste or filter system. Can be reduced down to 3" if required. 4" (110 mm) exhaust.
