Drilling Galvanised Steel Tank

[stevetheplumber]

forgot to say remember to get every bit of swarf out of the tank we used a big lump of putty to pick it all up thinking about it we used putty for a lot of things back then

I think the drawing shows the type electricians first used I know the plumbers type you are thinking of I knew these as Cookes cutters I think I still have some in the shed but finding them well thats another story...regards Turnpin

And these can cut a galvanised tank
Bit thicker than sixes shown!

I cut a stainless steel stockpot with one. It had a much thicker wall than a galv tank

Stainless will cut easier than galvanised imho

You need a top quality steel hole cutter, Bosch or similar

I like that, if been plumbing for 48years but haven't thought of that one as a temp' although I always drain down cylinders by syphonige( mains filled hose pipe attached to copper pipe placed in cylinder and hose chucked out of window.

I seem to think that a galvanised tank or unlidded plastic tank without byelaw kit does not meet legionella hygiene requirements so would be illegal to use for a cold supply for a pumped shower. (Perhaps this is just for commercial work - Please correct me if I am wrong)
