Closely Spaced Tee's?

Unknown

water does take the path of least resistance, that`s true, so you space your tees closely, so one pump wont over-take the other. OK?.........Whoops, sorry Brad!

Using 1-1/4" Primary loop piping, can the Closely spaced tee's be 1-1/4 x 1-1/4 x 1" therefore the secondary loop being 1" loop or do the tee's need to be 1-1/4" all legs?

Yes the secondaries may be smaller, they often are. Just be sure to keep the tees close together on the primary loop. No such thing as too close.

I thought I read somewhere that the tee's needed to be the same as not to restrict flow? Something about the water is going to take the path of least resistance and if the leg feeding the secodary loop was smaller it would affect it. I just don't remember, thus the question. Thanks

Closely Spaced Tees....

The tee run should be consistent but the branches should be sized for the loads they serve. Your main could be any size, 3/4", 1", 1-1/4", whatever, while the branches can be 1/2" if it serves the load.

Remember the branch is a controlled port (injection to the secondary on demand) and is unaffected by properly sized closely spaced tees.

You can even go up a size for the tees to further minimize unwanted migration into the secondary zone (or vice-versa).

Got it. Thanks.

ps. maybe I was thinging about monoflo tee's

Monflow Tees

Similar, only different! On the outside they look like closely spaced tees (on my old system inappropriately so) but inside, as you know, they are restricted.

Monoflow tees illustrate what happens when you DO restict between the tees; of course with Monoflow tees, that is what you want...
