Did you check if there was any sediment buildup when you installed the new fixtures? Sometimes when you switch to low-flow, the narrower openings can get clogged up pretty easily. Happened to me after I swapped out our showerhead—pressure dropped like crazy until I cleaned out some mineral deposits. Might be worth unscrewing them and taking a quick peek inside...
Sediment buildup is definitely a common culprit, but I'd caution against immediately unscrewing fixtures without shutting off the water supply first. I've seen folks accidentally cause leaks or damage threads by rushing into it. Also, sometimes pressure issues aren't just about sediment—could be a partially closed valve or even municipal water supply fluctuations. Might be worth checking your main shut-off valve position before diving into fixture disassembly...just to rule out simpler fixes first.

Totally agree with this. Can't tell you how many times I've been called out for an "emergency" only to find the main valve was partially closed or someone had messed with the pressure regulator. People often jump straight to sediment or fixture issues, but honestly, a faulty pressure reducing valve (PRV) is another common culprit that's overlooked. If your home has one installed, it's worth checking—especially if neighbors aren't experiencing similar issues.
Also, don't underestimate the municipal supply angle. Had a client once who spent days troubleshooting internally, only to discover the city was doing maintenance down the street and hadn't notified anyone properly. A quick call to your local water department can save you a lot of headaches and unnecessary work.
Bottom line: start simple and work your way up. Saves time, money, and frustration in the long run.
