"Ever considered flushing the tank? It seems unrelated at first, but sediment can really mess with overall flow and pressure consistency."
Good call on the sediment buildup—had that happen once myself. Another sneaky culprit I've run into is partially closed or failing shut-off valves. They look fine at a glance, but internally they're restricting flow. Worth double-checking those valves, especially if they're older... better safe than sorry when it comes to plumbing headaches.
Flushing sediment definitely helps, but honestly, sometimes the issue isn't even inside your house. Had a similar situation a while back—tried everything from tank flushes to valve checks, and it turned out the main water line from the street was partially clogged with mineral deposits. Ended up needing a plumber to clear it out... wasn't cheap, but fixed the pressure issue completely. Might be worth considering if you've already tried the usual suspects.
Good point about the main line—had a similar issue myself. Couple other things to check:
- Pressure regulator valve (mine was faulty, replacing it helped)
- Old galvanized pipes... they corrode inside and choke flow.
Worth ruling these out before calling in the pros.
