I HAVE A WATER SOFTENING SYSTEM PRE-RO SYSTEM. THE SOURCE OF MY WATER IS A WELL. THE PRODUCT AFTER SOFTENING IS PRETTY GOOD. THERE STILL IS A SULFER ISSUE. WE HAVE NOTICED A LOSS IN PRESSURE. WE HAVE HAD YOUR SYSTEM WITH NO PROBLEMS FOR 3 1/2 YEARS. WE CHANGE THE SEDIMENT AND CARBON PRE FILTERS REGULARLY. WHAT ARE YOU RECOMMENDATIONS ON TIME BETWEEN CHANGES? AND AS A HOUSEHOLD OF 2 PEOPLE WHAT EXPECTANCY SHOULD I HAVE FOR THE RO MEMBRANE? THANKS Jason
It is good that you are changing your filters twice a year. However, if you have iron bacteria it could be causing the sulfur smell and be clogging your softener. Do you have sludge in your toilet tanks? Iron bacteria as well as sulfur reducing bacteria can produce a sulfur smell. If there is a significant amount of iron sludge building in the softener, it could be the cause of the clogging. I would recommend calling one of our water specialist and order a water test, including the iron reducing bacteria and sulfur reducing bacteria tests. We can then see if there is iron bacteria or anything else that may be causing the loss in performance.
My 5-stage RO unit has lost pressure so I am going to change out the filters for the second time in 2 years. I have not changed the membrane, only the extra filters that were included with the original RO unit. The original and replacement filters did not include a Nitrate filter. What does the Nitrate filter do different than the standard filter? Is it worth the upgrade? Also, how can I get full pressure back in my RO unit? Thanks for your help.
The standard filter pack and membrane will remove 85-90% of the nitrate that is in your water. The specialized filter pack will increase that rejection to 99% or more. It all depends on what levels you currently have in your water as to whether or not it's worth getting a specialized filter.
Loss in pressure is norrmal for an RO system as the membrane traps more and more contaminants. We suggest changing the filters every 6-12 months and the membrane every 3-5 years. If you change your filters and still have low pressure, it may mean that your membrane has reached it's limit and it's time for a new one. If after changing all filters and membranes, if you still have low pressure, then that would be an indicator of some restriction in your system and it would warrant a call to our tech support team.
Another of the more common problems is a loss of pressure at the RO tank, which should be between 5-7 psi. You can check your tank pressure with a tire pressure gauge. If it is low, you can use a bicycle pump to re-pressurize the tank to the target range. (This should be done when the tank is empty.) We have a video on how to do this here:
