So I just received this. As many reviews say, the filter comes with no documentation. It should be easy to install (and probably is) but there is NO marking on the filter to show water flow. There are also no white markers/arrows. So, to everyone who gave 4-5 stars, how did you determine the water usage? If installed incorrectly, this could have caused one of the reviewers' filter to "leak"
