Jesus Christ I wrote a million things and my stupidity took over me and accidentally closed the window losing everything
Argh! what I just wrote a few minutes ago is that I'm working on a catalogue made for the town council wich they want to explain the process of water treatment. I have modeled and downloaded several pieces and I have it all separated but the final work will look like this
Took from the warehouse
As you can see the level of detail it's not what you can say "outstanding" but it does explain itself. I started modeling some pieces but when my bosses looked on my work they kept drooling on the keyboard because they never saw Sketchup before, now they are asking me to model some special pieces wich are A LOT and for my great luck they need it ASAP. That's why I came here hoping that a miraculous link could be delivered solving my problems haha. 
At the end I guess I'm going to model them. I already downloaded some rubys so that would help. When I'm done I will upload the valves and fittings hope you guys could use it.
Thanks
