Pump works just fine for water, you just have to have a proper water supply underneath it that won't get sucked up too fast. Odds are, you used something other than 4x redstone engines to power the pump, so it all got drained before it could act all infinite-like.Def works though.. And seems to supply plenty of water.. So strange how I pretty much have to give up buildcraft for TE with just about everything... I don't think I have any BC stuff running anymore.... Except the power... And that is not even using bc engines.
Ya. I pretty much live without it for many versions of Minecraft at this point.. I do give it a chance every update though.. And usually end up dropping it..Yes, I'm aware that Infi-Water is vanilla, just mods make use of it for mass transport.
Ultra always seems to be the most unstable of optifine versions, best to wait for standard, and version 4+ really to iron all the bugs out.
