Ro Di System, Water System for Aquarium, Four Stage Reverse Osmosis Deionization, with Color Change Resin Filter, 75 GPD Membran,

Quality, Value for money, Size. Everything is perfect!!

1) Hose fitting was not standard size for garden hose attachment (too small). I had to buy an adapter.2) Some of the pre-assembled filter fittings leaked at a slow drip.3) The output and waste stickers were reversed!!!! When I tested the RO/DI "output" water, it was 450+ TDS. Good thing I tested it before I used it!4) The correct RO/DI output (labeled waste) was 8-10 TDS. I was hoping for 0.

I hope I’m putting this thing together and flushing it properly. Exactly zero instructions were included with this filter. Thought I’d report that immediately since there’s basically zero reviews on this system. I’ll update this as I go. More to come...Ok so it’s been a couple days and I’ve been consistently reading 0 TDS on my model YL-TD52–A test meter. My tap has been reading 260-268 during the same time. It produces a large amount of brine, but I haven’t gotten all scientific and measured the ratio. It fills a 5 gallon bucket with pure water in an hour or so and I’d say the 20 gallon trash can in using to collect the brine is about 3/4 full. I’ve dropped a submersible pump into the brine and ran a 1/2 irrigation line out to the garden. Thus, it’s not going to waste down the drain. I’ve also connected some standard 10” filters with a 5 micron sediment filter and a catalytically charged activated carbon for reduction in chloramine prior to the ro/di. I’ll add a photo of my first set-up, but there’s a few more adjustments to come. FYI-the leaks are not from the ro/di filter, rather the 3/4”connection between the 10” filters before the unit.

I will have to stop by Home depot or Lowe's to get the right fittings. since the ones that it comes with, Don't fit anything in my house or outside. Directions are wrong. You have to clean out the carbon before putting the membrane in. And then you gotta clean that and then install the d. I.

The DI chamber leaks when any pressure is introduced. Like another reviewer, I stopped the leak with a few wraps of teflon tape and now all is OK. Just a bit of a pain in the butt is all. Don't go easy on the teflon tape. I needed quite a few wraps.

But the hose attachment doesn't come with a outdoor water hose attachment just a sink one.

I started to use it, after wasting 3 gallons of water, I measured 0 TDS water value and it is very successful. I did the installation simply with the instruction that came with it.

ad says it comes with a standard hose adapter and a standard sink water supply adapter. Neither one fits standard USA,l plumbing fittings. The sink connection is not standard and the hose connection is not standard. I don’t know where they use these type of fittings but not in the good old USA. Now I have to go to the hardware store like several of the reviewers and get new fittings.I guess you get what you pay for like everyone says.Misleading advertisement claimed to include everything needed. Maybe true unless you live in the USA.
