Rust spots on flexi sign of failure?

[Matt0029]

What causes rust spots on flexi are they a sign that the flexi will fail soon? Thanks

Often, not been cleaned properly of LDF or when a weak washing up liquid / water mixture has been used instead of LDF.

In the past I have seen stainless corrode in a humid environment (swimming pool area) when grinding of mild steel has taken place in the immediate vicinity and the debris not thoroughly cleaned up.

Have never seen an anaconda that has failed through corrosion, but believe that it can happen very quickly

Thanks and are rust spots a sign the flexi may fail soon?

I would guess that another cause could be flux not properly cleaned from the pipe surface.

From a GS(I&U)R perspective, if the corrosion is significant, it could be an AR under regulation 7. That only moves to ID when there is an escape of gas.

I have no real idea as to how you can determine how quickly signs of corrosion proceed to and result in a leak.

im guessing you mean a water flex matt

If you are referring to water flexible pipes, ignore my comments.

Bit confusing this one Matt if you mean internally on tap flexis then often it's caused by condensation cold water entering a warm environment via the Flexi much like a toilet cistern in the winter months they can condensate and drip, If you mean a gas anaconda then often it's LDF not been washed off after use causing pin holeing .

Correct yes it's a water flexi

Correct yes it's a water flexi

As above then bud worth changing em when they look shabby . Regards Kop

 

[Matt0029]

That's the flexi in question

 

[ShaunCorbs]

Condensation I would say

Thanks yes. I'm not particularly happy with the set up. I can't think of a way to pipe it without the flexi. It's a wirquin cistern they sell this part separately.
