I am in the process of building a home and just installed new delta shower mixers. One shower is near my pressure tank and has two shower heads on opposite walls. When the test caps were on I had ample pressure throughout the house as the well and 60 gal pressure tank are set to 60psi. Then when I installed the cartridges I noticed everything in line past the showers had a severe lack of pressure, down to just a dribble at the far end of the house. I narrowed it to one shower, even swapped cartridges thinking I had a bad one, but the same thing keeps happening. Regardless of which cartridge I use, when I hook up that one shower everything past it loses pressure. I am stumped, all the lines are red and white PEX. Easily identified and ran correctly. Anyone out there have any ideas???

How did you size the piping in the home?
1/2" PEX works for two fixtures and then you need to bump it to 3/4".
A two bath home needs to start out at 1".

It does start at 1" coming out of the pressure tank then tapers down to 3/4 after about 15-20 feet.

Are you talking about when they are in use, or not in use

WHere you branch off to individual fixtures, you really want at least the next size up pipe to help maintain maximum flow (depends on how many simultaneous uses will be off of that feed line). Plus, the smaller the pipe, the more dynamic pressure will be lost due to friction.
