Aquatic Life Replacement Filter Kit only lasting 3 months; is this normal?

[Joshua Jordan]

I live in NW Arkansas and get municipal water. The TDS out of the faucet is usually around 180-ish. I purchased the Aquatic Life replacement filter kit for my Barracuda RO/DI 4 part filter and I am having to replace them approximately every 3-4 months. I checked the TDS today for the RODI filter and it is at 130. I installed it in late May of this year. Am I doing something wrong or is it just the water here. Is there something that I can do to make the filters last long or is this just normal?

Thanks in advance for any advice,

Josh

What are you replacing every 3-4 months? It really depends on your water qualitity but you should not have to replace everything that often.

I am replacing all four filters: the sedment filter, carbon filter,DI cartridge and the RO membrane.

I thought I was supposed to replace all at once

Only replace as needed

Sedimate when the pressure drops across the filter. I change mine annually
Carbon as needed depends on what your water supply has in it for disinfectant. I change mine quarterly
Membrane change when rejection rate goes down/ I change mine 3-4 years
DI as needed. This depends on what is in the water when it gets to that stage.

can someone please tell me how to know which filter to replace? I am replacing all four every 3 months because I always test my TDS before water changes and about every 3 months my TDS goes from 1-5 ppm to around 140

Where are you measuring the TDS?

The membrane should last at least a year, and have 98%+ rejection if working properly. So 130 tds doesn’t make sense.

What water pressure do you have on the meter?

 

[KStatefan]

Test TDS of your source water
Test TDS after the water has gone thru the RO membrane (Less then 98% replace membrane)
Test TDS after the DI resin (Greater than 0 replace DI)

Sedimate replace when needed (When the preasure drops 5-10 psi across the filter)

Carbon filter replace when needed this varies depending on what your supply water has in it for disinfectant
