Changing Ro/Di Unit Filters

[brick-brothers]

Hey I posted yesterday that my ro unit wasnt flowing right. Well I took off all 3 filters to see if they was dirty. Come to find out that the first filter that the water goes into first was indeed dirty. I took it out and ran hot water over it and started rubbing off the red film that was on the filter. I put everything back together and turn the unit on. My flow was back to normal with the tds meter reading 0. So my question is, was i suppose to manually clean the filter or was I suppose to replace it?

I would have replaced it . Go on ebay and get a case of filters for cheap .I bought a case of 30 filters 15 sed filter and 15 co/carb filters for $30

o ok, this is my first ro unit. So now i know to just replace them. Thanks

If your unit doesnt have a flush kit on it install one- you flush it once a month or so and it will help keep the membranes clean for longer.

Depending on your water quality, the first filter can get gummed up pretty quickly. The RO membrane is really the powerhouse of the unit, and generally the first two canisters simply clean out the larger particles so that you get better efficiency from the membrane. While replacing them is usually the best option, I've rinsed out filters and gotten additional life out of them.

I was thinking the samething. Being how i rinsed mines off and used it again and still got a 0 tds meter reading.

You can get rid of all of the filters before the RO membrane and get a TDS of 0. The reason for the pre-filtration is to prevent unnecessary wear on the membrane, which is considerably more expensive than the pre-filters.

The filters, aside from the DI and carbon block are prefilters that trap some of the stuff before it clogs your membrane. Carbon removes chlorine that will damage your membrane, and the DI is for DI stuff. I can't think right now so DI stuff it is. And each filter gets proportionally used up. So its usually a good idea to swap out all of them unless there is alot of maintenance work around your area and your first filter got the blunt of all the junk in 1 hit.

DI stuff = Nuclear Grade De-ionization Resin.

MR SHO GUN, you should def replace them. Home depo has them and also I know bulk reef supply has them as well for the filters.

I think thats what happen to my unit. I only had it for a month and already the first filter was down for the count. But your right about changing all the filters at once.

Yeah im running new filters every 3+ months if im lucky. Ive been getting dirty water in my pipes every week or two which im guessing is from all the new construction in my area. Its usually about 2 months before my DI resin turns brownish, my first filter is all red and takes me 2x the time to make the same water i normally do. Then another month before my lazy self descides to take everything out and take everything apart to change the filters. TDS is always 0 but perfomance drops and my membrane takes a beating.
