I've noticed that before, and I think it may have something to do with the water going into it. I assume you use BuildCraft pipes to pump water in? In my experience, the Pumps in BuildCraft kind of flux in their pumping. Maybe try using engine generators or an energy link to power it? I know that kind of defeates the purpose, but that's all I can think of. If all else fails, I guess just try uninstalling technic and reinstalling it (copying your saves, of course).
