Home DIY

This has worked for me in the past

• Buy new tap
  
• Turn off the water before the old tap (either isolate all mains to the house or any stop cock before)
  
• Take off old tap with a huge mole wrench
  
• Cut your hand open / swear / etc
  
• Put some waterproofy stuff on the new tap (new rubber disc seal it came with, ptfe or apparently hemp on the thread) - Screw it on tightly
  
• Swear because whatever you do it is upside down
  
• Add way more ptfe like 8-10 wraps more and try it again, now you can get it the right way up
  
• Nip tight with adjustable spanner
  
• Turn on stop cock/ mains
  
• Check for leaks
  
• if leaks, put more ptfe in places that seem sensible
  
• repeat
  
• Use tap
  
  

If the frost damage is further upstream, replace more bits
