Store Bought or Home Made????

afilter, who do you have deliver RO water? The closest thing that I can find in my area (other than my lfs) is the water machine outside my local grocery store, has 5 gal for $1.50

I went with a local water supplier, similar to "Culligan". They sell/install water systems systems such as softners, RO, etc. I can pick up 5g bottles for $.40/gallon or they will deliver for $.50/gallon(larger amounts). I would avoid the grocery store because who knows when they last changed the filters.

This company is the same one that installed my in home RO system with an etra 40g holding tank with a float shut off.

If you have a larger tank the in home RO system is probably the way to go. I did haul water for about 18 months and cannot imagine going back now.

This is if you have a decent water source to begin with. I have city water which is not bad. If you are using some wells or get water directly from the sewer plant your membrane may only last months. Best course of action is to check you water periodically.
