Accepted Answer

Our recommended change is as follows:

Every 6 Months:
Alkaline Filter
Sediment Filter
GAC Filter
Carbon CTO Filter

Every 12 Months:
Post Carbon Inline

Every 12-24 Months:

Question 4

Is the UV light on constantly or activated by water flow?

Accepted Answer

It is always on, the only thing seperating the water from the uv bulb is a clear tube so the uv bulb is always on while plugged in.
