RO membrane ???

[Scudd]

A side from a high TDS count is there any other way to know if the RO membrane is done.. My TDS count is still 0, but its taking longer to make RO water.. I replaced the pre-filter and both DI canisters.. I've also ordered two carbon block filters and will replace this week.. The membrane is almost 2 years old now.

Is your water temp any colder? The colder the water, the slower the RO produces.

yeah, the water has been colder

Have you noticed a decrease in flow coming out the waste line?
