Fresh Water Tank Vent Leak Fix Question

[Docsouce]

I did a search on the Fresh water vent line leaks. I have a 26XD, it has 3, 1/2 inch vent tubes on the drivers side of the fresh water tank. If I put a cap on 2 of them, and on the third drill, say a 1/8 inch hole in the cap, would that be enough to let the air escape when I'm filling the tank? I understand some water will still escape from the cap with the hole but I'm thinking not anywhere as much as it would if they were uncovered, and after a while the tube with the holed cap would drain off and enable the tank to breath again. Just trying to think of a way to not have to crawl under the RV if I end up in a mud hole after a rain and need to add water.

Just got out from under the RV and I think I answered my own question. If I happen to get side tracked while filling the tank and because I have everything plugged up, The overflow has nowhere to go and could possibly make my a real mess out of things. I think I'll stick with the suggested fix.

In the "for what it's worth" department, our TT has two wide, but shallow freshwater tanks, so if we're off-level to the driver's side when we back into our site, water starts to run out. I put two 1/4 turn valves on the overflow lines, but I have to remember to open them to fill, close them until I get the TT level on the site, then open them again to use the pump.

We don't travel with a lot of water in the tanks, so I'm not worried about losing it on the road, just until we get from the potable fill to the campsite.

Thanks. I'll just have to put up a reminder or something. The city water feed fills the tank slowly. My last RV didn't have slides and the tank was under the dinning seat. It had a 1/4 inch line for an over flow. I don't understand why this tank has 3, 1/2 inch vent/overflow lines. Seems one would do just fine. We will boondock on the spur of the moment so I like to have 1/2 to 3/4 a tank of water on hand. After some mountain driving ,there have been times when I checked the water level only to find I've lost 1/4 of the water.. Gonna grab my inspection camera and get a good look at this setup.
Thanks again.
