Flexible tap connectors breaking

[doddsie]

I would be checking the rest

How do you check? I can't see that there will be any obvious fault.

I intend to swap them all over, but first I'd like to establish what the problem is so that it doesn't happen again. eg. faulty hoses? badly fitted? not suitable for the job because of high pressure?

I would swap them all to be honest. I cant' understand why you would have had three in the same property especially as they were from different sources.

Pressure wise, most things here are tested beyond 10 bar so If Matchless is correct with the 4/5 bar pressure, I cannot see it being that.

As far as the Plumber goes, I would not accept responsibility for materials that a customer supplied themselves either but the question still remains as to 'why' they broke. I can only speak for myself here but I would be wanting to investigate the cause of failure before I refused to accept any responsibility for it. Even if you had supplied it because the failure could still be due to an installation fault or error.

Can you not remove one of the flexes that are still in and see how tight they are?
Normally, you would be able to unscrew those with your hand. You might have to start it with a spanner/key but they shouldn't require much force.

Yes I can do that and if they are too tight, at least I know that was the probable problem. There's no way the plumber will accept that it was his fault though.

When I do replace them all, is there a better flexible pipe I can use? Any that are rated to a higher pressure? manufacturer's that are better than others?
I don't care about the price, I just want to stop the problem. The first time one broke was in the mezzanine at the top of the house and we bailed out over 300 litres from the basement.

I couldn't tell you a name to be honest. I don't tend to buy them separate. I always use what comes with taps. Your problem is an unusual one in my opinion. I think you'd be best off, replacing all the flex connectors and then at least you'll know you've more than likely eliminated any further issues.

Out of curiosity, are these all on hot water or is it both hot and cold.
If it is hot only, do you know what type of system you have. e.g. pumped, tank fed, unvented etc

if you supplied the taps then its down to you to do your home work contact the tap company who make the taps find out the working pressure of the taps ! what is the working pressure of your property! most inlet pressure is regulated to 3 bar
if your pressure is above this it needs to have a pressure reducesing valve fitted
