How long before a new whirlpool reverse osmosis fills the tank and stops draining? I installed the brand new system this afternoon and after 4 hours it is still draining. Does that mean the tank is still filling or is there a problem? Model is WHAROS5
That model can produce 18.4 gallons of purified water per 24hrs or about 1.3 hours per gallon. So in seven hours, a 5 gallon tank should be filled. There may be other factors that affect this. If it is still running after 10 hours, you've certainly got a problem. Note that every time you use the filtered water, there will be additional draining.
