Hi guys,
I'm after some advice if I may. As the title suggests I have a Pure Freedom 300 gpd RO. I bought this last November. I was advised at the time that it may be a good idea to buy a replacement pre-filter set, which I did. The guy also advised me that this should be changed approx every 4 months.
My tap TDS readings are about constantly in the 350-380 range. After the RO but before my DI this is normally in the low 30's. Now I must admit from November to now this has always been the case so I have never changed/used my pre-filter kit, until now!!
Over the last week or so my post RO figures have been about 40-45. Now I assumed that I probably ought to change the filters seeing as the guy said "every 4 months" & actually I haven't done so yet. So I change the filters, flush for approx 30 mins, check the reading & its in the high 50's (Post RO pre DI) I've flushed for over 2 hours & it refuses to drop any lower. So now I'm actually getting a worse reading than before changing them.
I phoned Pure Freedom to ask their advice & Frankly the guy ummed & erred a lot & said keep flushing it, & you need to change the pre-filters more regular as these protect the membranes. I explained that with the new filters I'm actually getting a higher reading than the old filters. More umming & erring, suggestion of more flushing & if that doesn't work I may possibly need to change the membranes ££££!! Frankly fairly unhelpful
MY questions are:-
1. are these TDS readings about right?
2. could i have some duff filters?
3. can you even get duff filters?
Also I have a small 10" DI filter. with the TDS readings going into this in the 30-40 mark I'm only really getting 1 full IBC tank (1000L) before the TDS starts creeping up & the resin needs changing again. Is that about right??
Thanks in advance for any help/advice you can offer
