Review on Lemoy Straight Connect Reverse Osmosis by Gary Morris

Fantastic accessories. None of them have leaked to me and all seem surprisingly well done. They even include little blue latches for the hardware. I have 2 separate reverse osmosis systems installed at home: one for drinking water, the other is a RODI system for my aquariums. Before purchasing these check valves, I would have had to turn off one appliance if I used another because I was using the same faucet and waste line. You don't want water to flow back out of whatever device you're using. do not use. With these check valves, I can now keep both devices on at the same time without worrying about backflow. Some reviewers mention that the check valves are buggy and won't let air in as there is a rather heavy, spring-loaded check valve inside that only opens when you suck on the right (gigity) end. Attempting to force air out (even from the right side) does nothing in terms of opening the check valve. My guess is that it probably takes 5-10psi of air/water to open this spring. Both ball valves in the kit work perfectly, there are no leaks.
