Waterproof 2: And This Time, It's Serious
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeWater. The bane of redstone engineers and tracklayers everywhere. It flows all over your builds and causes everything to fall off... Right?

Not anymore! Waterproof 2 simply blocks water (and other fluids) from flowing into redstone and rails. The list of blocks is configurable; the defaults are shown in the above image. Or, if you will, it puts the "oof" in "waterproof".
This makes use of a class transformer; it's a coremod, so keep that in mind.
Waterproof 2: And This Time It's Serious is a continuation/port/recode/whatever of Waterproof, by Vazkii.
Of course you can use this in your modpack. Idk is having to beg modders for modpack permissions still a thing? I hope not.
