Well I will tell you the reason for the question... my check valve in my RO uint stopped working which allowed the unit to continually push water through and out my waste tube into the drain pipe 24/7 which after checking back utility bills meant $100.00 to $120.00 per month extra on my bill for the last 2 years
and no I did not notice because my wifey pays the bills!
Anyway, gotta figure out if I want to continue using it or try the city water with prime...
Thanks for your replies and hopefully there will be some that use the city water route then I will not run into this problem again lol.
