Stack Plumbing Fixtures - Connectors

[Anonymous]

I have my plumbing fixtures reporting their fixture units, very cool, but When I go to connect a stack i don't know how to make the connector take the Fixture Units that the pipe is carrying and ad it up to it's own, I'm attaching a screen shot of a section where you can see that if I connect the plumbing fixtures to the pipes, the pipes carry the FUs (image left) on teh right you can see that the FUs don't carry when I pipe it as a stack. Any ideas? the connectors are linked within the family, Y just need to figure out how to add the FU from the pipes.

Thanks so much

Hi @Anonymous

Try this and I hope you can solve your issue

Hi @debimmanager

thank you for the prompt response. My workflow is a take off of Derek Main's class from AU 2016, and it all works great, until the plumbing fixture has to add FU and act as a fitting which is the case in a stack.

Thanks so much

Awesome because this class is great, so I understand your request and according to my knowledge of plumbing, what I could appreciate in your model is that direct connection of the stack with the plumbing fixtures cannot be done (right model in your pic), you can not connect directly the stack with the pipe. It is not an appropriate connection. It is just an advice.

Hi this is a great conversation but if you notice on the left when I take a pipe from the fixture and connect to a main the main keeps adding the FUs? This is not happening on the right when the pipe goes straight from one fixture to the next. They are the same family, it's two connectors set to global, it's working fine as a plumbing fixture (image left) when it has to do the doble task to work as fixture and fitting which is what it does in a stack it doesn't work. I tried changing the connector to fitting and the result is the same.

Thank you

Can you share your model?  if you prefer can you share via email? maybe you can show me just this part because of it is very difficult to give you a solution without the model, I would have to build the same scenario, and right now  I do not have much time.

Hi all,

I'm uploading a model with a vertical stack where you can see both ways of connecting the fixtures and where you can see what happens when it goes straight through.

Thank you for your time

Hi @Anonymous

Sorry for the delay but I had a lot of work, I leave the rvt. file with the solution and 3 photos with the changes you must make to the plumbing fixture.

Let me know if it works.

Thank you soo much for your time, for that I'll give you "Kudos" but I don't think you understand my problem, I need the stack to the right to report the FUs just like it does the one to the left, meaning each fixture ADDs fixture units to the pipe, that way I can size my pipe at the end. At this point notice that when they are stacked it reports it's own units but doesn't add the units it brings from the fixture above it. And that is the problem, I had changed the connector to fixture to see if that way it would solve my problem.

I missed the stacks the one to the right has to report like the one to the left. In short:

I need the pipe to continue adding FUs

I understand your request and try to solve it in several ways and even with a shared parameter and it was not possible for me to add the fixture units with a direct connection to the plumbing fixture. Even that direct connection to the plumbing fixture, in reality, is not allowed, only if, with a special system, I do not remember its name right now, but it is not very common to use it. I recommend that you make the connection as the model on the left has it. It's the right way, with an independent stack.

Another solution was using a shared parameter with called DFU but not appears in the TAG the FU. If you need I can share with you.

Hello,

Set the top connector to fixture unit and associate it to an input FU parameter, change the connector to calculated, this way, this connector will read the FU from the pipe on top, then add the value from the plumbing fixture and set this value to the exit pipe.

Hi @fabiosato

Thank you for illuminating my mind I forgot this part "associate it to an input FU parameter,"   I can solve it @Anonymous

I had it linked to the WFU (waste fixture units) shared parameter, could you explain your DFU parameter? or upload the model back, that looks awesome in the screen shot.

Thank so much

Thank you very much for your effort, again I want the same functionality of the fixture to keep track of the FUs, your solution still depends on someone imputing and adding FUs, and keeping track. If you notice when it doesn't go through the stack if you take a fixture of and cap that pipe the FUs change automatically. The whole idea is to help the engineers keep track of FUs to size the pipes and to use as much ADESK functionality to automatize.

Thanks so much

Hi Judy

Thank you for your interest in this subject. I really appreciate the effort that everybody has put into this, I still haven't gotten what I'm looking for. I want to keep track of FUs without having to manually add them, like in the example where the fixtures are not piped through but diverted to a separate riser. It works awesome in the flat, it's just this one last issue.

Thank you
