With GT fluid pipes, is it wrong to make a “loop”?
For example I have a large tank downstairs for sulfur dioxide, and I don’t want to have a pipe for adding new SO2 and a separate pipe for withdrawing SO2. I have been using one pipe for it all, and an underflow configuration from the tank output. The output of the tank uses a tiny pipe, linked back to the main pipe. This should keep a minimum amount in the pipe without blocking adding more.
Are there TPS or other issues with that configuration?
What about adding a pressure valve to dump excess on a loop?
