rodi longevity

[Josh]

The only solution is to increase the pressure to the unit with a booster pump. That will give you more life out of the filters but they will still clog very quickly.

The good thing about it is that if you are changing your first stage filter because it is getting clogged, your last stage (the RO) should last a really long time. Since that is much more expensive to replace I think it is actually a good thing that we have the water quality we do. In 2 years I have never replaced my RO, I change the sediment filter (it becomes brown very quickly) every 2-3 months.

For a fun test, take a paper towel and wrap it around your kitchen faucet and run the water through it for 5 minutes. That will give you some idea of how much mud is in our water supply.

i change my prefilters once a month as they visibly change color from the trapped silt and rust. when my RO was on the second floor of my house, i was able to get 3 months out of the prefilters but now that everything is in the basement i get to change my filters more because there is no settling of the rust and silt.

you can buy a prefilter for your main or just have add a larger 5 or 10 micron sediment filter before your RO to increase the life of the prefilter on the RO

I have a 10 micron sediment -> 5 micron carbon -> 1 micron carbo before my RO/DI, my 10 sediment turns brown after making about 200 gallons of water. I change my sediment filter very often.

First question, should I change configuration. Second question where can I buy bulk sediment filters.

Yes - you should change configuration.

Do you have chloramines? If not, you don't need two carbon filters. Try:

5 mic sed->1 mic sed->0.5 mic carbon
OR
10 mic sed->5 mic sed->5 mic carbon

If it were kosher for me to make commercial posts here I would tell you where to go for thsoe sediment filters...

Are folks interested in getting a group buy together for sediment filters?

 

[ari5736]

What is the difference btw the two different combos? If I think my water is on the "dirty side" would you recommend the first or second combo? I don't have chloramines, just chlorine. Thanks.

Yes - you should change configuration.

The smaller the pore size on your sediment filters, the more TSS you keep out of all downstream stages. BUT, the more sediment you trap, the sooner the sediment filter(s) need to be changed.

We hear a lot about heavy TSS loads in water from your area, so if it were me, I think I would install a whole house sediment filter at 20 or 50 micron (to keep the crus out of the entire house), and then go with this option at the RO:
5 mic sed->1 mic sed->0.5 mic carbon

Because the amount and size of sediment you have will be different for everyone, you may find you'll have to go through some trials with different pore sizes to see what works best for you. The good thing is that sediment filters are inexpensive...
