closely spaced tees seperation

Alaska Joe

is there a minimum that one set of tees (loop) must be seperated from the next loops set of tees?

Alaska Joe

minimum seperation distance between

two sets of closely spaced tees would be???

The closer,

the better, usually I use "close" nipples between tees(I`m an IPS guy). I believe the rule of thumb is 4 pipe diameters.

Interesting question Joe,

and I contemplated this myself the other day, so I decided on this drawing. It shows the distance from 90`s, so I used this measurement as my spacing between the sets of tees also.
BTW-Remember that the more secondary circuits you have, the lower the temp drop in the primary loop is as it approaches its end, so cooler secondary runs are typically picked-up last.

Nice job!

Thanks for the submittal. It was exactly what I was looking for. Have a great weekend!

I have successfully used the extruded manifolds from Souix Chief that have 1-1/4 trunk with 3/4 outlets at 4" centers for multiple zones of injection sub sustems without any apparent problems. I did take care to rank the temperatures as the trunk got longer. makes a nice neat header.

Do You

Have a part # for that Sioux Chief manifold? Thanks!

I don't...I've gotten them at Ferguson before and at Pacific Supply. They come in one inch, 1-1/4 and 1-1/2 with 1/2 or 3/4 outs on them at 3 and 4 inch centers. I usually use the 1-1/4x3/4x4 so there is room for pump flanges and valves. Makes a neat manifold, and, though not strictly proper by the numbers seems to work very well when using pumps for zone control. Trunk temperature is pretty even as all the primary circ has to do is get through the boiler and around the trunk. The secondary circs pull right off the trunk and back into the next outlet down-stream.
