Weil McLain ultra

Snowmelt
Member Posts: 1,428
I am going to have a chance to repiping a Weil McLain ultra and the indirect, would you use black pipe and copper.
The next question is that it’s a 155 ultra put I want to put 1-1/2 pipe . Will the bigger manifold fit the 155. The ez manifold that is made for that is 1-1/4?

1-1/4" copper L can easily move 15- 16 gpm at 4fps velocity. You could flow 18 gpm and still be below the 5fps limit for hot water.
Why the 1-1/2"?Bob "hot rod" Rohr
