After doing the rounds online, we decided to buy this unit as it ticked a lot of boxes for us. 6 stages, good quality, good access to replacement filters, good price and good customer service from John and his team.
The unit arrived within days, and after studying the installation instructions for an hour and placing everything out on the floor, we decided to give the installation a go.
The unit came with everything we needed, except for the 12mm drill bit to fit the faucet and thread tape for all the fittings, so we had to go to Mitre10 to get these, and we also bought an extra stainless steel spring washer and flat washer as there seemed to be one piece missing in the faucet set. Not a major, just hard to figure out which piece it was missing as the graphic explaining the pieces wasn't super helpful.
Once we had these, we went at it, and everything came together pretty smoothly. We had a little trouble with the press fit pipe fittings, but that came down to our inexperience in using them, not a fault with the parts themselves. We also made the mistake of not tightening down the RO cartridge lid enough, so once it got pressure, it started to leak out. Again, our fault not the unit fault, it's just we had this problem because the pipe didn't line up with the press fit fitting if the cartridge lid was fully tight, so we had to remove the pipe and cut a slightly longer one and route it ourselves. Easy stuff.
Once these problems were solved, we let the unit run for 20 mins to clear out the system and boom, tasty fresh water.
Everyone in the house is super happy and noticed the difference straight away.
Here's to a future with ACTUAL clean water!
Thanks John for your help. I highly recommend this product.
