Water bottles

Just heard report on radio Manchester saying there’s been an increase in accidents with bottles bursting.
Life span is max 3 years.
Chuck on the tip
next to mine which is ancient.

Most hot water bottles will have a big number embossed into them inside a symbol that resembles a daisy. This number shows you the year that it was made, so for example, 15 would mean 2015, and 20 would be 2020.

Yes...very dangerous...they do perish
....over 3 yrs old...Bin them...not worth the horrific burns they cause.

The oven shelf won't burst..
