2.  Relieve pressure from the water heater through the T&PR valve or a hot tap. 
3.  Remove the drain line from the T&PR valve. 
4.  Unscrew the T&PR valve and remove.  
A quantity of hot water will discharge from the tank during this process. 
Personal Protective Equipment should be worn to prevent scalds or burns. 
5.  Confirm the replacement T&PR valve is the correct rating and refit using thread tape.  
6.  Refit the drain line. 
7.  Close the hot tap and restore water supply.

T&PR valve. 
5.  Outdoor models: Remove holding screws from the jacket top and remove jacket top 
and flue terminal assembly. Indoor models: Remove the plastic anode cover. 
6.  Using a 27mm tube or socket spanner unscrew and remove the anode(s).
