We used this PUR 35
watermaker for 6 months while sailing through the
Caribbean. We would run this 12 volt
watermaker for 4-5 hours day for pure
drinking water. It worked fantastic. Allows you to sail for longer periods of time without having to worry about
water and filling up. It draws about 4-5 amps and makes about 1.3 gallons of
water every hour. In November of 2010 we purchased a new membrane for the trip (valued at $450.00) making this a steal for the
price. It comes with several new filters, the new membrane, extra spare
parts, and all
cleaning solutions. It is a fantastic unit. We are only selling because we have purchased a
new boat that already has a unit on it. Thanks.
