Bathroom sistem input/output

[Primus]

Hi... So i play this game a lot... To much actualy...

Ok... back on topic

I made a self-sustaining bathroom. (3 showers, 6 lavatories, 2 water purifiers) After a while i noticed that the output pipes are full of polluted water, so i made a pipe buffer and connected it. after 2 cycles or so i noticed that the buffer is also getting increasingly full. So i need to ask. What is the Shower and Lavatory input/output ratio? Because it seems that the output is larger than the input. So that means infinite water?

You can easily check it yourself ingame.

Lavatory is the culprit. You need to get rid of excess.

So... Make a buffer with pipes and a separate water purifier and when the buffer is full run the purifier till its empty. Its like cheating   The more your duplicants ****, the more clean water you can get. No more shortage of water lol

You can use a variant of this design:

When water reaches the bridge, it will enter it unless the other end of the bridge is blocked. So when the purifier stops working because the clean water pipe is full, any excess liquid will go to the vent (or whatever other device you put there) but as long as the pipe is not full it will keep cycling.

send the extra to fertilizer machines

Well food requires water, so assuming the game conserves mass, then you would have a net increase of water in the system. So if you want to make it a perfect cycle, you'll have to outflow some of the clean water to a reservoir that your duplicates use for making food.

 

I did try a closed loop once for my polluted water, but ran into the same backup problem. I tried to fix it using an outflow pipe and a liquid valve to minimize loss. But I had trouble getting the liquid valve to work, it ran at full capacity even when I set it to zero flow, and there wasn't any kind of work order on it for me to prioritize assuming it required a duplicate to apply the changes. So I just went back to dumping everything into a reservoir and sucking it back up with a liquid pump.

That's very bad assumption for this game.

That's a bug, dupes won't come to adjust a valve if it's blocked. Safest approach is to build a valve on empty pipe and adjust it before any liquid comes to it. But you don't need a valve for this.
