draining down wb 28cdi

angelf · 4 May 2010

I note from a lot of posts on this site that its best not to use the iso valves under this boiler to drain down the c/ h and hot water because they leak.
I need to do this 2morrow (to change a water to water hex) so what is the leak free alternative please?
