Flexible connectors

[Dave1980]

Has anyone had any trouble with flexible hose connections? I have fitted some to a bathtap as the bath was tight to a wall, and after a year the hot water connector burst. I replaced this with another (longer) flexihose in case the first hose was stretched and under pressure, now 6 months later this new hose has burst (fraying the metal sheating in two places) The rating on the hoses was 65 degrees C. and the hot water is set at 57 degrees C.

Is this a known problem on flexible hoses? or are the hoses poor quality? I won't mention the make as I do not want to give the manufacturing company a bad name they may not deserve. Lets just say they are sold in B&Q so not some cheap internet buy!.
Any help would be appreciated. Thanks

System3 is your man for these.

IMO you should of used bent tube.

But yes. Flexi's do fail. I would look at the Hws and see if there is any potential for over temp or high pressure

Flexible connectors have a rubber washer/seal and like all rubber, it degrades over time.

Are you tightening them up too much? Should be hand tight then a 1/2 turn tweak with a spanner (imho).

Agree with SimonJohns.

System3 will give you the best advice on flexis.

Thanks for the replies, I realise that bent tube is the best but in this case it was an existing bathroom and to try and get to the bath, meant taking out a sink and plinth that had been tiled around. This is proof that the easeist way is not always the best way !!!

"dontknowitall" I don't think I over tightend it, but if I did, would that cause the flexihose to burst a couple of inches from the connection?

As I am new here, I assume System3 is another forum member. Am I correct? and how do I get intouch with him?

 

[SimonJohns]

Yes system3 is a forum member. And he's not a great lover of flexi's

If you do have to use a flexi. Get a good quality known brand. And tbh I never tighten mine any more than 1/2 a turn over hand tight

I cannot see any reason for the failure. Do you have any photos you could upload

Doesn't look like
Corrosion?
Pressure?
Heat?
Mechanical damage?
Rats?

You're correct. Over tightening wouldn't cause it to leak at that point. (I'd assumed it was at the tap joint.)

Re System3, it's a recent "in joke" on the forum. He hates flexis with a passion (and he's not the only one.)

By the way, Welcome to the forums!!

No Pictures, sorry I have dumped the flexi pipes.


It does look like a pressure failure, and I did tighten them more than people are suggesting, so could be my fault.

Funnily enough I joked about a Rat chewing it, but it has been the same flexi burst each time, the hot supply, the cold seem fine, I suppose that then opens up the "Heat" question.

Looks like it is going to have to be out with the sink and tube the bath for safety.

Just seen "dontknow it all" reply so it is not me over tightening it then.....PHEW! bit of a relief there!!

just because you bought the flexis from b&q doesn't mean they are the best quality only higher prices imho
