Evening All,
Just looking at installing an immersion heater in to the top of my tank, only to discover the thread is there for one, but it seems to be sealed, did think it would be some sort of cap, but seems pretty solid bit of copper, Tank is probably well over 20 years old, guessing it just a tease or did they have to be drilled out back in the day ?
Any help appreciated.
Thanks
Gary
