Tool is the metal bit sticking out from behind the label.

Yes you need to drain it, usually not the whole system though!

Yeh thats alls you need, you just need to drain boiler, i personally would NOT isolate boiler, open drain tap on ISO valve and as its draining pull and push diverter pin to get as much water out as poss, when it stops change the cartridge really easy to do on these, or you could use iso valve to turn off boiler or drain the whole thing if you feel better doing it like that

Never touch isolation valves if you ask me! Asking for a leak!

I am sure a more talented worker than me could do the ISO valve method. I'll do the long hand method as I'm heavy handed.

Thanks again.

Pipes look ok, pressure gauge fitted on the return doesn't rattle.

New diverter fitted.

Heating behaving, hot water hotter than before and boiler much quieter!

Thank you to everyone who has contributed. You have really helped me out.

To be fair, after all the advice given here it was a simple job. I'm used to working to greater torque settings, but being gentle and following the instructions carefully meant no nasty surprises.

Had I not been given the advice I have been I'd have been up the creek without a paddle!
