There is no theoretical limit on the number of Tee’s used on a main – provided you are only asking for one of them to deliver at a time. In the real world, you may be in the shower and the toilet flushes – you get the picture. Then the question becomes the desired GPM per fixture.
With sixty PSI you should have no problem with your bathroom install. That’s my $0.02.
I get the difference between theory and reality...makes perfect sense..and if someone flushes...I'd have to survive
I guess my concern is that if I would go through all the work of extending the pipes, and if we'd have really poor pressure and flow, it would be quite dissapointing
What are the options for dual showers/shower heads?
I was thinking two seperate valves would make sense to save water if only one would be used. Could I then split it to two 1/2" pipes?
