Problems with pipes

[BrendyBear]

I recently got this game in a sale and I'm really liking it, however I have an issue that I haven't been able to figure out. Can someone please explain why the water isn't getting past the T-intersection in this screenshot?

The water goes up to the T, but the T join itself is empty. Both pipes entering should be under pressure, and there's no water after the T, and a water vent shortly after that.
Do pipes get blocked by objects and need clearing?
Is there a glitch at that T-intersection?
Something I've missed?

I had this issue as well, I rectified it by making a seperate cut off seemed to do the job. Thinking maybe water pressure is glitched with T sections.

When you do systems like this (2 producers on different ends with some consumers between them) plumbing gets confused and does not work properly. Try to avoid it. The reason is - there is no pressure, there are "packets" which have to "decide" which way to go. Because of it when there are multiple available path things break.
To fix specific system connect the pipe from water sieve to the system near battery/hamster wheel instead of where it is connected now and it should work properly.

You can also use bridges to set flow direction (liquid can flow through bridge only in one direction) and set "priorities" (water going from pipe into bridge branch-off always has higher priority, from bridge into pipe - lower).

In this case you should use a liquid bridge instead of the T-section, the pipe behavious does take a bit to get used to.
But 2 inputs meeting eachother in the middle mostly end up bugging.

Use bridges to enforce the flow direction you want. This also helps with packet merging and priority,

This is my solution. I can really see how the water is being treated as packets here. The water packets in between the greenhouse and water vent seem to want to try to go back to the greenhouse instead of going out the vent. I've turned off the hamster wheel to the pump for the greenhouse, so I'm hoping the system will clear once those packets between the greenhouse and the vent have been used.
I guess I could use a plumber to empty the pipes if I wanted it cleared ASAP, but I'm not in any hurry to empty that pool of water.
Cheers for the advice on using water bridges to force flow direction, I'll keep that in mind.

One issue here is - water from sieve will never reach the plants this way. Because when you run the pipe directly through consumer (or bridge) it always has higher priority than water continuing to flow down the pipe. In this case you did it with vent, which will never be full (unless it is submerged), so all the water from the sieve will always go into those vent.

I never wanted the water from the seive to reach the plants, I just wanted both pipes to output into the water tank. Eventually I will reconfigure it so the farm is irrigated from the tank, but atm I'm using the water I'm pumping into the tank to irrigate so I have less pumps running.
Haha my solution didn't even work. The water through the farm just stopped halfway through even when both pipes were connected directly to the vent.
I ended up adding a water bridge between the farm and the vent to force the direction, now it works perfectly.

A good rule of thumb is to not have extra inputs including looping pipes on different sides of T sections and if you are use bridges at junctions to force one way flows.
