Most kitchen taps and some bathroom taps feature convenient swivel spouts.
These taps usually have rubber orings and a nylon bush in the spout for water seal and swivel action. To maintain good spout swivel action try the following:
- Turn off the water supply to the tap
- remove the spout (normally held in place by a grub screw at the back)
- clean the exposed part of the spout and the open hole where it came out of
- apply some vaseline to the o-rings and nylon bush
- replace the spout
