good product This spanner undid a very tight immersion element without problem, the only weakness being the user. 16 Oct 2014
Immersion heater box key Simple but very effective. £9 for the box key against possible £500+ plumbers bill if old tank got damaged using stilsions or cheap plate key. 3 Oct 2014
