Floor pan drain plug

Has anyone ever installed a floor pan drain plug, behind the rocker panel? It seems these floor pans always rust there, in this same area among YJs, likely where water is able to settle. Even with bedliner, theres processes that'll degrade materials inside out - corrosion, etc.. I've had a most of my drain plugs pulled for awhile for this reason.

Not sure exactly where you mean, but you can punch a hole wherever you want. If that's what you mean by installing a plug. I think most of us just leave the plugs out of the original holes. More holes isn't going to stop rust caused by road treatments, and the only holes that are going to do anything are those at the lowest point.

I mean.. curious if, because of the "common issue" at the drv & passenger front floor pan (the low spot where water settles), if anybody thought of or experienced this or a fix. Also affected is the adjacent rocker, alongside the floorpan. Just putting that out there. Also, what kind of insert, grommet is in there to put the plug in, if for some unforeseen reason it should need to be plugged.

The plugs are readily available. Here is a source a quicky search turned up.

https://www.amazon.com/Upper-Bound-F...s%2C178&sr=8-3

If I was going to add new holes, I might go with a 7/8". Because that is a common conduit knockout size and all kinds of plugs are easily found. More common and more variety than 1" size.

I bought some rubber plugs at lowes...I think 1-1/8"? Work like a charm for me.

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

1 1/8" would be 3/4" conduit knockout, also a common size. So any home center would have that size. I'm surprised those fit in a 1" hole, but then I don't trust Amazon on the actual size either.

7/8" is 1/2" conduit knockout.

You could move out here and solve the problem permanently without drilling holes in anything. Thousands of miles of off-road trails and hardly any bugs. Very few things want to kill or eat you here.

Both the gasket under the windshield frame AND the body seam between the cowl and base for the windshield frame. You know, the seem that is a couple three inches below the gasket. I KNOW one of mine leaks there.

If you cannot fix it with a hammer then it has to be an electrical problem.

One might argue that you can fix the cause or source of the leak or where the water is coming in (or have the top off) only to find the repair failing or another leak at another time. Still the problem exists that once the water finds its way in, it finds this settling point, rusts, etcetera You know this @Boojo35 , @bruinjeeper

Then you fix that leak...and the leak after until you are leak free.

If you get caught in rain and/or do a deep water crossing... at least you know the water is in there and act accordingly.

If this is such a big issue for you... seriously by all means get a hole saw sized to your liking and just add in a hole at that spot and treat it well... sand...prime...paint... top coat and get a corresponding plug and plug it up.
