Rubber Cored Braided Flexible Connectors

That says nothing. It's all may and could

Ok all I know is they have been and are being de listed by the authorities there is nothing to stop joe the plumber fitting them just like joe does not have to use Wras approved products. In my side of the business all these things matter. The only legal criminal control is GSR. However to fitting unapproved items leaves the door wide open to civil litigation and could invalidate his insurance if indeed joe has any if things go wrong, there is little difference in the price anyway.

The authorities are nanny states taking notice of people wanting to make a fast buck off of them.

I use flexis and use ones that are wras approved. If there was a real issue then they would be off the shelves

The thing is in commercial settings legionella can be a right pain and expensive to control. The bacteria hides in little gaps, cracks and porous materials. Organisations get disruption and spend money tackling it and then in systems with things like degraded flexis, blend valves and corroding systems, colonies of the bacteria are not removed properly and re-populate the water system. I think legionella is relatively harmless for healthy people to encounter too, just that when a place like a hospital has it present, it can lead to outbreak and very costly follow up action.

I can see why they'd want to get rid of rubber flexis in commercial operations or hospitals. I did some reading up on the rubber and the manufacturing of these hoses and was surprised to find they aren't extruded from a hot plastic soup, but rather made from granules that are pressed and heated together. When these hoses break down they break into their granules again. This must leave lots of hidden surface area to harbour microbes.

Finding a load of black rubbery grains inside the tapping on an expansion vessel make me start researching it. I like the idea of flexible stainless steel flexis I have to say.

I take it there is analytical data to back this up and not just scaremongering?

I dont read much or see stories of horrendous legionella outbreaks.

That could be because of prevention efforts. It's like when people said the Millennium Bug was a damp squib. It was because of preventative efforts. I worked in the IT industry leading up to the year 2000 and it was a real problem. It was overstated and sensationalised by the tabloid media but it was a real problem.

At the end of the day I will no longer supply EPDM cored flexis and will use stainless steel flexible pipes. I sold 10,000 units last year of the relevant unit and constantly try to improve my products. Anybody else can plough their own furrow, my post is for info which is a big part of PF
