I know this is a silly question, but to replace a gas hob with a new one. Do i simply turn the gas isolator valve next to the cooker to off(this is in the kitchen cabinet under the worktop below the boiler). Once ive removed the cooker which i'm also replacing, can i simply disconect the gas supply from the hob?
Ive obviously isolated the cooker circuit before doing this, but if the gas fitting on the hob is situated in a different place on the new one, can i use copper tube and compression fittings to extend it?
Ive seen people say only to use solder fittings, but is this really neccessary?
Also if I can use compression joints is there a substitute to PTFE tape?
Also when i disconnect the gas there will obviously be gas in the pipe from the isolating valve to the hob, any problems or recommendations with this?
thanks......
