Two Flexhead connections off of a cross?

[vargasmarco123]

I am doing an add relocate job and was wondering if anyone had any information on running more than one flexhead connection off of a single outlet. I want to attach them to a 1x1/2x1x1 cross with an upright head on the top and a flexhead hose off either outlet. think this bird will fly?

or maybe even attach another tee off of the side outlet with a short nipple and run the hoses off either of those ends.

That requires a calculation big time, unless there was a huge safety factor or designed to handle that demand it may not work.

Additionally just shifting one of the outlets to a new mechanical tee would take some demand off that junction but just a sliver, try that alteration in your calculation if its close.

Calculate the system demand. Welcome to flexhead world. You are responsible for your design.

Depending on the length and manufacturer you are using, you could have 35'+ of equivalent feet per drop. Anytime you go from hard pipe to flex head, you are going to need to calculate the system.

I would also say to calc it if you were trying to hard pipe 2 sprinklers from a single outlet as well.

Good luck with it.

I don't see a problem if I understand the question correctly.

The correct terminology for the fitting is 1"x1"x1"x1/2" cross and not 1"x1/2"x1"x1". Not meaning to be picky on the fitting but it through me at first.

It may be fine, but now you are taking 2 sprinklers from a single outlet that had 1 before. Also, if it was hard piped previously, you are now adding the extra friction loss from the flexhead component. I still say it needs to be calc'd. But, that is just my opinion and is worth what you are paying for it

Travis,

Having to calc it is a foregone conclusion.

 

[TravisMack]

OK. From reading the initial post, I was thinking he was asking if it was possible without calculating it.

If the question is: Is this arrangement possible? The obvious answer is yes. Will it work hydraulically? That will have to be determined by calculations.

Travis and SD2,

It's nice to see two guys I respect come to the same conclusion I did. It helps me keep my perspective on what's right or wrong. Thank you.
