I'm sure this is a dumb question but today is the first time I have heard that term. I've looked for a definition but can't find one, only references to future tees. My assumption is a tee with a stub out for connecting new work "in the future".

Is this a good assumption? Are there any issues with them? I was reading some NYC plumbing codes that prohibited the use of them.

If that is indeed what they are, I have installed them on water lines and a gas line in my current renovation.

thanks

Yes, it's for "future" work.
I've seen in the codes, that they don't like them, has to do with dead end pipes that don't have water regularly going through them, thus becoming old.

However, many times, we do put in futures to make it easier on the next plumber.
 
thanks Terry, I'll leave mine in and hopefully the inspector won't have an issue with them.
 
I put in futures all the time in commercial work for domestic hot and cold water and dwv. Of course what is usually being constructed are office buildings where futures are needed for anticipated tenant finishes.
 
tees

Inspectors and codes do not like them because it makes it too easy for the residents to add on and do unapproved, and uninspected, additions to the system.
 
I haven't run into any inspectors who have a problem with futures here as long as they are labeled as such. Guess thats just another example of how things vary in different parts of world.
 
With things going to pex whats the 'future' an extra manifold with barely any connections on it?
