I purchased the 150 GPD upgrade for my 6 stage universal a month and a half ago and it seems to be producing much more than 2x the production. My 5 gallon buckets fill in about 15 minutes and now it seems like I already need to replace the filters. I was under the assumption that they should last at least 6 months and I only got the unit in November. I'm getting a reading of 110 TDS out of the 3rd line. Is there a way to reduce the pressure or is this working as intended?
