2 Pin to 4 Pin Circular Adaptor (Older Distiller, Newer Pump or Auto Drain)

All new Precision Water Distillers (2018) along with all new pump and auto drain accessories utilize a 4 prong circle plug that only connects one way. This 4 prong plug is the same style as our 7 prong system used for the water storage tank float system that has always been installed on all distiller units. This upgrade was due to the manufacture discontinuing 2 prong terminals.
Simply look at how many prongs your connection has or review your series number printed on the manufacture's label on the left side of your distiller next to the model and serial number to determine if a pump adapter is required and which adapter you should order.
Series 0017 - 0001 utilize 2 prong pump and auto drain connections requiring either
pump kit series 0001 & auto drain series 0002 (while supplies last) or adapter part# 500514.

Series 0018 and higher utilize 4 prong circular connections and require pump kit series 0002 or higher & auto drain series 0003 or higher.

If purchasing a new pump only (no kit) part# 500018, you will use the existing pump plug so it should marry up with your distiller without concern.

If purchasing a new pump kit parts# 500007, 500007-lessfaucet, 500016, 500016-lessfaucet, 500008, 500017, 500008-lessfaucet, 500017-lessfaucet, 520004, 520004-lessfaucet
