If you set the floor mats correctly thru the carpet then insert the plugs after that you'll have no leak problems either wat in or out! See video I guess, great mats IF installed as instructed!
Not sure about the Sahara, but on the Rubicon, the carpet is already cut and is being held in place by two tabs. Take a look at your carpet where the drain hole is. If the carpet is cut, pull out the carpet plug. The drain plug is located beneath that; pull it out and insert it in the floor mat.
The carpet should be already cut on top of the drain. It is held on by a small piece of each end, you can literally pull them apart with your fingers. Pull the drain out of the floor pan and install in the mat. Make sure when you put the mat back in you seat the drain into the floor pan.
Installed! Thanks to this thread! And the rear is slick too because it’s in 2 pieces but locks together in the center.OP take a look at this link.
I have the updated ones with seal, still no chance of keeping water out in a creek crossing where water is above floor heightThere have been some design improvements to prevent water from leaking in, including the addition of a seal to the drain funnel. I haven't tested it, but it's definitely an improvement.
Use a better, thicker O ring maybe? There's always this https://www.jlwranglerforums.com/forum/threads/mopar-all-weather-floor-mats-drain-sealing.9836/ , but I'll admit the 20 year old inner tubes I used eventually deteriorate and need replaced.I have the updated ones with seal, still no chance of keeping water out in a creek crossing where water is above floor height
