johnny11 Posted April 6, 2012 Report Share Posted April 6, 2012 As we now have a hose pipe ban here in the south east, i am looking at getting a inline Reverse Osmosis water filter. Can anyone recommend a good one where the cartridges are not too pricey to replace? Ta Link to comment Share on other sites More sharing options...
eldavo69 Posted April 6, 2012 Report Share Posted April 6, 2012 MrMe is the RO expert as he had a decent setup for his fish tank. IIRC the 0ppm filters don't give true RO water. Best bet is to look on eBay or similar, lots of companies selling decent canister systems for window cleaners for circa £100. A lot less expensive than the nicely packaged "car cleaning" filters.

patently Posted April 6, 2012 Report Share Posted April 6, 2012 So what would you use as the water supply? Link to comment Share on other sites More sharing options...
Twinspark Posted April 6, 2012 Report Share Posted April 6, 2012 I'll never forget a Coca Cola rep. standing up in a meeting to present a bottle of tap water which had allegedly been purified using 'reverse osmosis'. Needless to say, they were quickly forced to withdraw the product from sale. Link to comment Share on other sites More sharing options...
Daz Posted April 6, 2012 Report Share Posted April 6, 2012 I used this solution during the last hosepipe ban in 2006. That tub full was more than enough to clean the car. Link to comment Share on other sites More sharing options...
Paul Posted April 6, 2012 Report Share Posted April 6, 2012 I did the same. 25l drum and a couple of hose lock fittings. Essentially a static water source, and iirc your were allowed a 1m hose from a tap to fill buckets etc. (Thames Water) I just used the less than 1m hose from container to feed pressure washer.

NewNiceMrMe Posted April 6, 2012 Report Share Posted April 6, 2012 How would RO save water? You get a 5:1 ratio of waste to RO water! Cheap filters mean bad water and swifter replacement. Plus a DD-50 unit will take 24 hours to give you 100 litres on average water pressure. I don't understand what the aim is? Link to comment Share on other sites More sharing options...
Calm Chris Posted April 7, 2012 Report Share Posted April 7, 2012 I'd imagine it's to clean the lime and chalk that us Southerners have in our water. Cleaner water means less rinsing, thus less water? Link to comment Share on other sites More sharing options...
eldavo69 Posted April 7, 2012 Report Share Posted April 7, 2012 Maybe less water for doing the car but your shooting yourself in the foot as you waste 5l of water to produce 1l of RO. Link to comment Share on other sites More sharing options...
johnny11 Posted April 7, 2012 Author Report Share Posted April 7, 2012 i`m just going to be using it for the final rinse, just got to choose the right set up, don`t really want a system set up under the sink, just a simple as mentioned portable one if they are around.

eldavo69 Posted April 7, 2012 Report Share Posted April 7, 2012 If it's an inline system it won't be a proper RO system but as I mentioned before your best bet would be a window cleaning filter. Link to comment Share on other sites More sharing options...
eldavo69 Posted April 7, 2012 Report Share Posted April 7, 2012 Something similar to this: http://item.mobileweb.ebay.co.uk/viewitem?itemId=150792110524&index=20&nav=SEARCH&nid=40279859759 Link to comment Share on other sites More sharing options...
johnny11 Posted April 16, 2012 Author Report Share Posted April 16, 2012 The ri vessel I thought was what I needed, but this is only deironised water, and as I live in Surrey the water here is very hard so this would be no good. Today I spoke to the company that sells these.. 4 STAGE WITH DI AQUARIUM RO REVERSE OSMOSIS SYSTEM UNIT MARINE DISCUS FISH | eBay and I reckon this is the answer, at only £45 seems to be the way to go, the only down side only this only does around 15 litres per hour so will need a storage butt, but I think this is the best way.

Tarmac_Terrorist Posted April 17, 2012 Report Share Posted April 17, 2012 I have a DI water filter for final rinsing purposes. I get 0 ppm water now. I also occasionally use the water for my fish tank water changes (but add minerals for that purpose) The resin is quite expensive but lasts a long time if you're careful. I fill a watering can and give the car a final rinse that method.

OGWT Posted May 7, 2012 Report Share Posted May 7, 2012 CR Spotless - water is passed through a column or membrane to remove ions present (ion exchange) using polyvalent ions such as magnesium (Mg2+) ++ and calcium (Ca2+) ++ for Na+ ions. Deionised resin strips out all the minerals and impurities from the water by exchanging Ca and Mg ions for H and OH, the resultant H20 is completely clean and 99.9% pure “Filtration Methods” - http://www.autopia.org/forum/guide-detailing/137955-filtration-methods.html#post1465231 Link to comment Share on other sites More sharing options...
johnny11 Posted June 10, 2012 Author Report Share Posted June 10, 2012 Well I bought one of these 4 STAGE WITH DI AQUARIUM RO REVERSE OSMOSIS SYSTEM UNIT MARINE DISCUS FISH | eBay Washed the car and used the R O water to rinse, NO water marks after the car was left to dry naturally, should of had one of these years ago. The only thing with this is you have to store the water as it only does 50 u.s gallons a day, but what I did was put it on in the morning and within a few hrs I had 3 water storage bottles full.
