Esshup,
Thanks for replying!
1. Thanks, I will look into the poly. We had a couple hundred feet of pex on hand would be the only reason why we would use it.
2. How long do you think a run needs to be before I should upgrade from 1/2" to 5/8"? 1/2" is significantly cheaper, but I don't want to use a product that wont work.
3. Maybe I will make my own manifold. I was reading somewhere else on this forum that sometimes PVC isn't as easy to make small adjustments on.
4. Would you happen to know how much CFM a diffuser can handle? For example, if there is 3 cfm, is it better to run all through one diffuser or is better to split into 3? Scratch the CFM question, I see that it is on the item description at your store/ Are Vertex diffusers good below 16'? Or do I need to look for a different diffuser below that depth?
