I was paying $0.75 per gal
If you do the math, even at $0.40 per gal
. You will get off a little cheaper, and if you figure in the cost of gas to drive to LFS
and your time driving. You are much better off.
Mine takes about 2-3 hours to fill a 5gal jug. If you have higher water pressure than I do, it will take less time. My pressure at the unit is about 42 psi. If you have 45psi or better, you will get a faster fill and your DI
resin will last longer (ie..more gallons per refill), which will lower the overall cost per gallon more.
I got mine from www.thefilterguys.biz
I have the OCEAN REEF + 1 FIVE STAGE 75 GPD RO
with an upgrade to Dual DI
for $30 more since I had lower pressure.
It's a great unit, and the company is VERY helpful. Send them an email with what your RO
needs will be, they will tell you exactly what you should get. When I had the problem with the low water pressure, they troubleshot it with me and came up with a solution. Excellent customer service.
