I assume the pipe thats tied into the top of that 2" combintaion is a similar fixture on the opposing wall and they are using one pump to serve both.

It's all 1.5" and yes it's catching an additional lab sink on the other side.

A broken clocks right twice a day and nobodys perfect but it was still a hypothetical and theres not a water ram that operates with HIGH reliability at those pressures...water is too viscous

You know I'm right. But I will argue. I have some time. The Bachelor doesn't come on for 33 minutes.

Try reading post number 14 that I made explaining it could be done with a loop vent....but its already roughed in and the only option is rip it out or install a mechanical vent. Mechanical vents are legal in Fl as i understand. My first response was to say you cant just plug off the inlet and run everythign into the vent......the pump will not work like that..it must be looped some kind of way to allow the circulation of air. The pipe sizes are too small to do it any other way.

You cant use mechanical vents on these pumps. This is the closest thing for specs I can find right now. Loop vents are illegal too.

Ok here I found it. The reason it was done that way was because the sinks were not back to back. They were offset from each other by about 2 feet. So I had to go between drawers to get to the pump. And being an orthopedic rehab center they need all the space for drawers that they can so they wouldn't shorten any of them down. It passed inspection, it was in lakeland, Protech probably knows the inspector. I didnt have enough depth to drop straight down with the ptrap its self going right into the pump. http://www.lgpc.com/ProductFiles/OM/993167.pdf

What the fugg are you talkin about man? Are you serious or is this just a personal attack?

I was slow from Nov of 08 until around March of 09. It has been steady since then. Now it has gone from steady to busy. I'm not big time compared to some. Compared to you, I prolly am.

Back to topic.

Do manufacturers instruction trump code in Florida House? Here they do not. I think they do in certain states or areas though.

I always think of right or wrong as compared to my code.
