Bullheaded T on return?

I understand why a bullheaded T should not be used w/ hydronics. But, I'm wondering if one can be used on the RETURN. This would be two 1" runs going into a 1 1/4 bull. This configuration fits my boiler room set up.

    For all the same reasons you wouldn't put it in the supply....

    No. Water is like my ex-brother in law. Wet, lazy and stupid. Using bull headed tee's will produce those results. The path of resistance continually changes with bull headed tees and subsequently, the flow will also change continuously.

    There are no less than 360 ways to use any fittings. :-) You can figure out a way to do it the correct way. You won't regret it.
