I've just had a flexible hose burst.
7 years old under the bath and connected to the hot tap. The braiding was completely corroded and the rubber pipe split. The flat below flooded.I had no idea that there was an issue with these but can see from old posts that this is a common problem.
Now I have to try and think of all the other places/jobs where I have installed them.
A plumber has told me only to use WRAS approved, which the ones from Wickes are. Pretty sure the duff one came from Screwfix.
