I have no idea what the 3 filter system is. I've heard it mentioned previously but all the major suppliers of RO units seem to sell the 2 filter system (Sediment and Carbon)
I think the answers have already been given it seems Grippa is the best option for delivery, but as for the Carbon filter it all depends how much you want to spend and how often the ones that Gardiners used to sell are only good for 37,000 litres were as these ones also sold by Grippa http://www.gapswater.co.uk/acatalog/Pentair--pentek--CFBC-Chlorine-and-Cyst-Reduction-Filter--0.5-Micron-CFBC.html#SID=550 are good for over 75,000 litres as for buying sediment filters no doubt they can be bought of Ebay for cheap enough Sediment filter with free delivery
The 75,000L pre filters have a micron of only 0.5.
Oh well I've got 2 so will see how things go I check my sediment filter on a weekly basis and as mentioned previously I have no issues with sediment , If I could use the 20" blue ones previously sold by Gardiners I would but can only accommodate 10" pre-filters in my shed, ultimately it depends on your water quality my tap tds is a max of around 78ppm at its worst were as I am guessing your tds is 200+
Yes mate, I’m Thames water, it’s equivalent to using water straight out of a swimming pool ??
"I phoned Pentair yesterday and was informed they block up much easier, even with a sediment filter"
After almost 11 years I am still learning, but this post has answered a lot of questions and made a lot of things clearer, I have also learned for the first time to check pre-filter specs rather than just buying whatever and changing them whenever.
If they are still white and don't feel gritty to the touch then they will fine to continue using for the foreseeable future just keep an eye on them
I know what you mean mate. I think the problem with these systems is they're so complex and there is so little information out there. I remember when I was looking to get an RO and watching videos on YouTube. Oddly enough the best, most informative video I found was by Doug. This was long before anyone on here recommended Daqua. The issue is these videos are absolute gobbledygook to someone who doesn't have the slightest knowledge of RO systems.
I had to call Doug a couple of times. Top bloke, really helpful. I always order my resin from Daqua or Gardiner's. So many suppliers out there have a bad rep when it comes to actually supplying the correct resin. Pure Freedom once sent me resin that seemed really wet compared to usual (Same brand) It didn't last as long as the it had previously. People reported they were once sending a completely different product and claiming it was the same spec. I tried Unger resin once, it was good but didn't quite last as long as Tulsion stuff does.
Having what you have gone through and you're still window cleaning have to say well done and keep it up.
Hi mate. Do you know what size tube you have going to your DI. I’m asking as I’m planning to get a inline TDS meter and they all seem to have 1/4 inch JG fittings as standard.
So sorry mate, I must not have spotted this at the time. It is 1/2 inch JG tubing. Daqua sell the Murlock connections for the in line system. Would be worth giving Doug a call to check these are correct but they look like the right ones.
Just to update on my purchase these don't last for 75,000 litres as stated the carbon filter should have seen me through for till May 23rd and have only lasted 9-10 weeks and processed approximately 37,000 litres of combined waste and pure, my production had been slowing down a bit I thought and after 8 hours my R/O hadn't even produced 200ltrs when I got back home last night so I checked the carbon filter and it was knackered, I have had to put another one in which is the same again.
