i do what mike does. i run off of the tank.

the way you calculate how often you regenerate is you find the grains of hardness of your water. in my case between 15 and 20. i use test strips to test. then you take the capacity of the unit you have. in this case 12000 grains and divide it by your hardness in grains....(not ppm). 12000/17.5 is 685 gallons before you have to regenerate.

so i get about 4 tank fills in the coach before regeneration. it uses a 4lb box of table salt we get at sams club for about a buck.

i looked at the on the go softener and it was over a hundred bucks more. so i went the cheaper route.

i do flush it by just hooking up to the water source for a few seconds each time before i hook it up to the coach. when i am done i put it back in the bay.
