Diverter Tee Spacing

Tom Minz

I Want to extend my mono-flo system and add some cast iron baseboard to it. One 12ft section and one 4ft section. Is it advisable to keep the tees the same distance apart as the width of each section and how close would be too close without installing a valve between the supply & return tees? Thank you for any thoughts!

Yes

Keep the distance the same as the length of radiation. The flow would diminish as the distance of the tee are set smaller. Using two venturi tees rather then one would increase flow. If the radiation is lower two tees are a must . If you stagger the tees between two loops, it increases flow for those loops. Using a valve between the tees would increase flow on that loop but would slow the flow for the rest of the house.....
