Injection System spacing

Injection System spacing

RE: Injection System spacing

Can anyone give me info on how injection/rejection works?

RE: Injection System spacing

I don't know that there is any typical spacing versus pipe diameter.  

...which may be the reason that no one else has answered as well.

RE: Injection System spacing

Maximum spacing between the tees should be less than 4x the pipe diameter of the primary pipe in order to minimize the pressure drop between the supply and return tees. You want to minimize the pressure drop to hydraulically separate the injection pump system from the primary system.

John Siegenthaler has some great articles on hydronic system design.
