💧 YZM Connect Reverse Osmosis System: Transforming Your Water Quality Review

My 5-stage reverse osmosis system is 16 years old. I just disinfected it and changed all the filters and membranes. The last water came out at 33ppm. It turns out that the check valve is defective. After installing a new YZM check valve, the drinking water level drops to 24 ppm. In addition, the non-return valves adapt perfectly to the membrane body with a little Teflon tape. Highly recommended.

Images of this item (part of the product description for IE) clearly show the security clips (blue tips) however the security clips are NOT included. While security clips are technically "optional", I prefer the added security. If you've ever wondered about the damage water can do, those $0.01 pieces of plastic aren't necessary at all.

I was actually pleasantly surprised at how well these check valves perform! I was expecting them to be cheap and light but instead they are heavy and well made. I found the internal structure of the o-ring to be better than what I bought from BR and MD. You will not be disappointed with the quality of these valves. I run them at 70psi and they are fine. I suspect they will easily hit 90+ psi due to thicker plastic and good o-rings.
