A while ago I asked the question about removing a tank heater from its
glass tube for repair,
I have worked out a way to do this, in under 2 minutes without any
damage
or even marks to the rubber seal.
Consider the rubber bung, to be like a cork in a bottle, external force
will not remove the cork, unless damage is done to either the glass tube
of
the rubber bung, But internal force will remove the cork / bung within
seconds.
I have a small air compressor in the workshop, this together with a
S****ts
ball inflator does the job, If you push the inflator down between the
glass
tube and the rubber bung, then attach the air line, and slowly fill the
tube
with air, the internal air pressure will force the rubber bung out.
The inflator will need to be inserted in front of the temperature control
as
anywhere else there is a plastic ridge under the rubber bung, which will
prevent the inflator going into clear air space, but where the temperature
control is there is a clear space below the bung.
When you have the bung clear of the tube, carefully remove the two
pressure
clamps holding the element to the thermostat, leaving the element in the
tube.
When the repair is completed simple push the rubber bung back in the
tube.
