    It WILL leak out of the box!!!
    2 Stars
    It WILL leak out of the box!!!
    First, before you do anything, replace the one-touch fittings that are on the UV sanitizer!!! Mine came with silicone and thread tape on them and leaked once the system got up to around 22psi. Almost all of the one-touch fittings on the system are pretty bad quality. Some of the fittings can’t be replaced so you just have to cross your fingers and hope they don’t leak. One way to give yourself a better chance of the system not leaking is to go ahead and replace all of the tubing that comes with the filter system (including the tubing already installed on the system). When you install the new tubing add a small chamfer to the outside of the tube before installing it into the fitting to avoid nicking the o-ring (they make a tool to do this). Check the pressure on your supply tank, mine was at 2psi. The flow rate is pretty bad on this system and the RO membrane definitely isn’t 2:1 rejection, it’s 4:1. My tap water has 178ppm TDS before the system, 4ppm after the RO membrane, and 42ppm after the (mineral?) filter. I placed a T next to the tank so I can access the RO directly for my fish tank. My system is inside of a leak proof enclosure with an actual leak detecting sensor. I wouldn’t mount this under my sink at all, you’re asking for damage trusting this. It’s ok for what it is but probably better to look elsewhere.
