Filtex either automatic or push button and light. When I moved back to Chicago and was installing this unit, MD had just brought out a set of retro metal inlets very much like the old Filtex ones, but updated. The unit doesn't start until you insert the hose or, if the hose has a low voltage control, until you flip the switch on the user end of the hose. The best of both worlds. These are the ones I have. The ivory ones were meant to blend in. These definitely stand out.
