Replacing the hot water sink valve in the master bath

The hot water faucet valve leaks through the shaft of the valve when turned about 45 degrees.

Will remove the old valve assembly (Price Pfister brand) and replace it. 

Removed the old assembly.  The valve seat area looks ok.

Local hardware store had a replacement valve. 

There's a plastic washer that goes under the valve.  Will put some Teflon tape on the threads to seal also.

Applied the tape and put the plastic seal on.

When starting the repair, the hot water shut off valve was very difficult to turn.  Had to work it loose by turning back and forth quite a bit.  Though I might have to replace the shut off valve but it worked loose eventually & worked OK.

The cold water supply like has corrosion on the metal sheathing.  Will have to replace the line soon...  (project for another day)

Finished replacing the valve.

There's quite a bit of hard water deposits around the base of the fixture.

After cleaning the hard water deposits...  All done.  The new valve works well.
