I feel that PARC is a name much more suited to the point of sale PMUP. I've been through three in less than a year. They are only used for ten gallon water changes every 10 or so days (I'm not good at doing weekly changes. Note that they were not used for mixing salt water...just to transfer pre-mixed salt water to the sump. I'm not even going to attempt to go through Neptune's customer service again to replace this boat anchor. Picked up a Sicce and will use that to transfer the water. I've no idea why Neptune doesn't come out with V3...perhaps one that works longer than a few months. Off of my soap box for now. lol
