Very low supply pressure to the hot water for one bathroom sink. No issues to the other sink, shower, or bath nearby. Checked the aerator & replaced the handle cartridge before verifying low pressure from supply valve to the handle.

Next step will be to remove the line from the supply valve to the sink to verify pressure at the valve. If pressure is still low (& assuming the plug doesn’t release with the valve open for a bit), what are next step suggestions for potential plugging in the attic supply line to only that faucet?

Your problem is one of inadequate volume. Are you sure the supply valve at the wall is fully open? No kinks in the supply line from the wall valve and the faucet?

I can feel water moving as soon as I open the valve, but the flow/pressure remains the same as I open it further. No kinks in the line.

Hoping the test at the valve will indicate a blockage between the supply and the aerator, but we shall see sometime this week.

Years of unfiltered well water filled my pipes with iron. Some were worse than others. Several 3/4" lines had only a pencil width of free space in them. Could be something like this, or sediment. Hopefully its just in that hose.

Have you worked on this any more?
