I have a Triangle Tube Solo 110 propane with internal pump. Taco 504 controller, Two pumped zones being supplied off main and returned to the return main.The photo shows the end of the loop with radiant and mixing valve. Do I need a bypass  between the supply and return before mixing valve. This system has been working as is for 4 years with no problems. Had a HVAC  friend look at it and he indicated I should install bypass.
