I am thinking of switching to PEX from a copper in my current bathroom renovation. This question pertains to a possible pressure loss in a shower head.
Here is what I am planning to do. I will be using Grohe iBox Universal Plus Rough for shower/tub (two function only). The supply pipes will be 3/4", the pipe that runs out from the iBox that will connect the tub spout will also be 3/4", and the shower pipe extending from the iBox will be 1/2". In a remote area, about 5 feet away from the shower I am thinking of installing a manifold with valves which are going to be 1/2" PEX Valves (all copper). So, here is the issue I have. If the PEX running from the manifold is 1/2" with an additional coupling 1/2" to 3/4" down the road (so I can connect the pipe with the IBox 3/4" supporting supply pipes), will I loose a pressure in the shower head?
Thanks for your help on this,
