Mekanism version: 1.7.10-8.0.2.201

Now levers and redstone dust affect a range of 3 pipes/tubes blocks, instead of just one. Also "redstone sensitivity"=on is the default on placement.

Suggestion: wouldn't it be better if Mekanism had valves instead of levers cutting off pipes? http://en.wikipedia.org/wiki/Valve

Fixed.

By the way, I love the idea of valves. Definitely considering!
