chrispy Posted April 24, 2009 Report Share Posted April 24, 2009 Have just bought & fixed up a new RO unit - my last one succumbed to the frosts of the winter & several of the filter housings broke. Having learned my lesson I have set this one up under the Kitchen sink unit (just hope it doesn't leak) I was hoping to get away without having to get one as the last one supplied more water for the iron than for my plants. This month we have only had 5.7 mm of rain in North Norfolk so I was getting a bit desperate. The latest unit came with a TDS meter & although the unit is still strictly flushing out I have obtained a reading of 014 ppm against 217 from the tap water. Is this a reasonable reading? What range is OK for CP's? Cheers, Chris Quote Link to comment Share on other sites More sharing options...
Amar Posted April 24, 2009 Report Share Posted April 24, 2009 Hi Chris, 14ppm is perfect, one says the range should be less than 100ppm, and the very careful among us say less then 50ppm. So, you're more than fine. Quote Link to comment Share on other sites More sharing options...
Dicon Posted April 24, 2009 Report Share Posted April 24, 2009 That will be fine, rainwater will probably average about 50ppm, My RO has a polisher on it and I've had readings of about 1 or 2, but the filters need changing now, and readings are in the low teens for me now. I'm certainly not in a rush to replace filters yet! Quote Link to comment Share on other sites More sharing options...
DaveC Posted April 24, 2009 Report Share Posted April 24, 2009 Hi Chris, I'm thinking about getting an RO unit. Which one do you have and would you recommend it? Quote Link to comment Share on other sites More sharing options...
Dicon Posted April 25, 2009 Report Share Posted April 25, 2009 I have a 4 stage unit from Ro-Man.........Just Google Ro-Man. The output to waste ratio is poor due to water pressure. Ro-Man reccommend 4 bar+ which most of us just don't get! Simply Control also do one that requires no pre filters and I wish I had tried this, but I really cannot say if it would be better or worse! I think you will be hard pushed to find anyone who has used different ones to compare directly. If you really need one get one, but if you can store enough rainwater to see you through any dry spells then I would just do that. PS. I use a huge amount of water and use RO as a back up in times such as these, and also to feed my Hydrofogger. Quote Link to comment Share on other sites More sharing options...
-=Joel=- Posted April 25, 2009 Report Share Posted April 25, 2009 Though I don't have one, people recommend adding a booster pump to get a better output. May only be worth it if its the main source of water. Quote Link to comment Share on other sites More sharing options...
chrispy Posted April 25, 2009 Author Report Share Posted April 25, 2009 (edited) Thanks for the figures folks. The one I bought is by Vyair - a 5-stage RO unit. Bought as a 'Buy Now'on ebay. It is only 50 gallons per day but that is more than enough for me. Cost was £119.99 including postage. Improvements on my last one - has an electric pump which is pretty quiet - therefore no need to buy one and no low pressure problems - free TDS meter & a spare set of filters. Also good backup & spares for this unit . Amazing delivery - less than 24 hours from ordering! Have fitted this in the kitchen so shouldn't have freezing problems. If you are capable of doing a bit of plumbing it is not too much of a problem to fit as long as you have nearby a mains cold water pipe - electric 3 - pin plug & somewhere to get rid of the waste water - either a waste pipe to the drains - or, what I have done - into an outside water butt for my wife to water the garden - 340 ppm TDS - just checked - rain will dilute this - if we ever get any!
