Hydro-Logic EvolutionRO 1000 - Manual (Page 10)

Tested @ 77F and 500 PPM source water. Flow rates will vary depending
on source water, temperature and PPM’s.
IMPORTANT NOTE:
The flow rate of product water can drastically decrease due to low psi and
low temperature, especially in the winter. In some cases with cold tempera-
ture and/or low pressure predicted flow rate can drop by as much as 50%
or more. A combination of cold water and low pressure can drop flow
rates even further. This is the case with all Reverse Osmosis technology and
is not unique to the Evoution-RO1000. The ratio of waste water to product
water can also get drastically worse due to low pressure and low tempera-
ture. You can overcome some of these issue by increasing pressure with an
optional booster pump, HL#29014, or increasing inlet temperature. We do
not recommend hooking the Evolution up to your hot water tank lines
because hot water tanks contain lots of minerals and the water can be too
hot. A safe way to increase temperature is with an on demand or flash style
water heater set at below 100F or 37.7C. For people with adequate
pressure but decreased water temperature a flash water heater is a great
way to increase flow rates.
The flow rate of purified water will vary depending on 3 factors:
