I dont doubt that the pex is more restrictive. I just think that the flow rate is so low due to the low flow taps that the restriction in the plumbing is a nonfactor. This could be checked by checking the pressure at the input to the tap vs pressure in the basement (while the tap is on) if someone is really interested

11 pressure reducing pex fittings in the first 3ft... That's just the first 3 feet. Copper fittings are female with a larger ID than the straight tubing.

It's as much a factor or as the areator is..

There are many ways to plumb a tankless or tank. The better way just costs more

pressure drop across a restriction is dependent on flow rate - 0 flow means 0 psi loss - I just think those low flow taps just dont allow enough flow for it to be a significant factor. Ill stop beating the horse now though.

Thats quite a hack job. The fittings cost more than the pipe so surprised they used so many. So much for gently curved corners instead of hard 90s
