Under my sinks and toilet we have flexi pipes fitted. On the downstairs bathroom sink, upon putting the hot water on, the flexi burst and water spattered out non stop. I had to turn it off from isolation valve until I can get it fixed in the mean time. Do flexis have a lifespan and are they rubbish compared to good old soldering copper pipes? The flexi that burst was roughly 10 years old. I’m worried that the other flexis around my home might burst one day. Is it worth getting them all changed when I’m doing the one that is currently burst? Do people on her have problems with flexis?
