A: The system’s GPD capacity is achieved when you have the following conditions for your source water: 77°F, 500 PPMs, 60 PSI. If your source water is colder than this, or your inlet pressure is lower, or your PPMs are significantly higher, then you will experience less than the rated GPD flow rates. HydroLogic provides solutions to these less-than-desirable source water conditions. For instance, we have a pressure booster pump for low psi, pre-filtration for high PPMs, and cold water specific membranes. Call us at (888) 426-5644 for information.
A: This can be due to multiple factors, such as clogged sediment or carbon pre-filter, clogged or fouled membrane, or changes to source water conditions. The quality of your water, frequency of use, and timeliness of pre-filter changes will determine how long your system performs at peak capacity.
A: This is typically due to deterioration of the membrane as a result of exposure to chlorine. The purpose of the carbon filter is to remove chlorine from the water. If It isn’t changed on schedule, chlorine will pass through to the membrane and degrade it, causing more water to flow out of the purified line and an increase in PPMs.
A: If you’re using the 2:1 flow restrictor, that means the system will produce 2 parts waste water to one part purified water. If you’re using the 1:1, you should have equal parts waste to purified water.
A: Over time, the automatic shut-off valve (ASOV) can accumulate scale and become clogged, causing it to malfunction. If you experience your waste line continuing to run after the purified water line is closed, please give us a call at (888) 426-5644.
A: This can be due to various reasons, including Teflon tape at threaded fittings, tubing not being pushed in all the way to the quick-connect (QC) fittings, or improperly seated O-rings in pre-filter and membrane housings. It is also important to make sure the ends of the tubing have a clean cut before inserting them into the QC fittings (see page 11) Please call us at (888) 426-5644 if you’re experiencing any leaks.
A: This can be due to freezing conditions, excessive pressure spikes, or long-term exposure to high intensity lighting.
A: The pH of the purified water depends entirely on source water chemistry. Customers can experience either slightly lower or higher pH due to their source water. This is completely normal for reverse osmosis (RO) technology. Since RO water is almost pure H2O and has no ability to buffer pH, the actual pH reading will not be accurate until you add minerals back.
A: The flow restrictor determines your waste to purified water ratio. HydroLogic has always provided two options for the waste to purified water ratio, because water conditions vary wildly across the world; one fixed ratio would not work for every water condition. Please see page 6 for more detailed information.
A: Here are the most common challenges when filtering well water:
A: There are different methods of treating iron depending on how much iron is present in the source water. The easiest way to know how much iron you have is to get your water tested from NTL.
A: If your carbon or sediment filter appears to be red, maroon, orange or brown in color you have iron in your water. You may also notice that your sinks and or toilets also have this discoloration. See an example image below of a system that was used to filter water with excessive iron levels.
