Connector Diameter and Flow?

[TimeDivided]

Hi folks,

LTR,FTP here. After years of reading and trying to get a handle on what it will entail, I’ve decided to DIY a PEX Conversion on my 4BR, 2BA Ranch. Current system is mainly copper trunk and branch. I’ve checked with code office and no permit is necessary in my area.

New system will go from well pump to a sediment filter, through a water softener, through the water heater, and into a 20 port pex manifold with ½” ports to fixtures. The Manifold can accept either 1”, or ¾” inputs with included reducers.

My Question is this: My Well Pump appears to have a 1” Output pipe, but all of the pre-manifold appliances (Filter, softener, heater) appear to have ¾” intakes and outputs. Would there be a noticeable gain to using 1 inch pipe pre-manifold, considering that I’ll be restricting flow down to ¾” at each appliance? I understand that flow rate will be that of the narrowest piping in the run, but I cant seem to find an answer as to whether or not ¾” fixture ins and outs are going to reduce my flow to that of ¾” pipe. If so, I’d rather forgo the added cost of 1” pipe and reducers.

Any insight would be greatly appreciated.

common practice would be to run your line 1'' full size. use 1x3/4 reducers at the equipment, keep line full size to the manifold block

a tip, run 3/4 to your bathtub/shower

Thank you very much for the reply. So even though my connectors temporarily restrict the diameter, I'll get better flow with a larger pipe?
I mean I guess it makes sense, bigger diameter, less resistance. Thanks for the help.

same thing your saying,

more volume, the bigger the pipe the more volume you will get at the fixture.

even tho you are reducing at the equipment, you will still maintain your volume.

pressure is always constant, it is determined by the pump, good luck, any more questions. holler back
