How can i fix these blocked pipes

[Lithrien]

I have thiş plumbing system and now 2 of my water sieves don't work because their output pipes are blocked.It was fine before i added 2 more water sieves and i had to add them because one was not enough.I also want to purify polluted water i dont have enough water in my world.(The liquid storage is just there for trial)

[Yunru]

I think the... Algae Press, is it?

Whatever the lower building is is stopping any flow, as the water is being pushed both left and right at the same time, and thus not moving.

 

Oh and of course, bathroom loops are net positive, since the dupes are, er "adding" to the system, so it'll back up without some form of storage.

 

EDIT: Oh wait, I'm missing the obvious. You've got a star branch. Those pipes leading up and across aren't crossing (you need to use a bridge for that), they're merging.

There are several problems in water flow like Yunru said (a picture of what the water wants to do below) 

Spoiler

I circled the problematic spots where the water flow has more than one options and the vent if you want your bathroom to work at all times. Every time water crosses a T or X section it splits equally to any direction

You can use bridges in order to have liquid flow a certain direction in a strait line. You can also use bridges to cross over a flow if that is what you wanted to do

 

A quick fix would be to connect the output of your water sieves and then pass it through the bathrooms (to work as -what I think- you did before the blocking and vent at the end)

It looks like you're trying to do something like this.

May I ask what's the purpose of the double buffer?

In partial flow situations a reservoir will often end up with a small amount of liquid at the output, which completely blocks flow for that second.

The double buffer delays this from happening until at least the pink circle has backed up to 10kg.

When this occurs, the pink buffer tops off the partial packet when it exits, allowing for uninterrupted flow.

[TheMule]

I've seen that happen, never understood the cause. It seems there's a 1 packet buffer inside the reservoir that doesn't refill as steadily as it should.

The double buffer fills thanks to the leftover from the merging with the algae distiller if I understand correctly. Every second 400g of p water accumulates inside the buffer.

This reminds me of a similiar problem with valves set at about 9kg/s (I don't remember the exact value), which would result in the valve emitting much smaller packets now and then. That was before a boiler and of course caused all sorts of problems. I had to solve it with 2 valves in parallel IIRC.

With only the exception of bridges and valves, all green outputs are 100% blocked when there's any content in the pipe. This is why the reservoir is unable to top off the small packet.

Yes, it is essentially the same problem. In the above image the output is limited to 9600g/s, essentially no different from a valve.

Oh. I think I get it now. I thought it was only a merging problem...

 

Instead they are blocked not only when they are at a junction (I mean, two pipes connected to the same green port) but also when they are connected to one pipe only and they emitted the blocking liquid. I knew that one green port would be 100% blocked by another one, even if emitting less than full packets.

I've never realized that they could block themselves! TVM now it makes sense.

I'm not sure about pumps tho. They definitely are blocked by the tinest packet already in the pipe, but they never block themselves with partial flow. Or at least, I've never noticed it.

It's even worse with pumps because they can output partial packets themselves when blocked and furthermore take 1 second to startup.

Although it helps greatly, one buffer isn't enough for continuous flow.

[TheMule]

Wow that's nasty. It's time I double check all my piping. TYVM again.

[nakomaru]

Here's a great 30kg buffer to fix pumps.

Wow thank you so much i am quite new to the game and i learned so much lol my brain was working simplier
