PTF Tape and Compression Joints

[TMHM]

The flex is that I use do not have a built in ballofix ( is that the correct term) valve built in, they are seperate items. I understand what you are saying, but why not just get a tap flex that has the correct fitting?
As an example...

In my experience what tends to happen is that there is a 15mm ballofix in place as isolation to the tap with 15mm copper running up to the tap rigid all the way with a tap connector on the end... someone wants to replace the tap, they shut off a ballofix, undo the nut and olive then remove everything from ballofix up to and including the tap...

A new tap is fitted that comes with copper tails, the person fitting then gets a tap connector flex, fits the compression/ pushfit end to the tap tail and the tap connector end to the ballofix ...

Personally I'm not a fan of tap flexes, in the above instance i prefer to hard pipe up to the tap tails, but that's just me

Agree with you on separate taps but not mono blocks

I am a tad confused here, as I am regularly using flexi hoses connected o a ball type stop valve when connecting to taps. All the flexi hoses I have, have got a compression fitting at one end, so I cannot see the problem.

No problem at all if you use a compression ended flexi.
It is the flat washered ended flexis that are the problem because the majority of work I see, they have been tightened to a isolating valve. The sharp edge of an iso or any other compression fitting risks an eventual leak.
I prefer to fit full flow iso valves where handy and pipe up from them in copper to correct distance for to meet the tap flexis, connecting to them using male straights, or sometimes male bends if pipes a few inches to the side, for example. That gives a flat face against the flexi washer. But some on here have the exellent idea of using spare radiator valve tails tightened onto iso valve for the flexi.

Here is one I had to replace the work because the hidden pipework had been leaking and eventually came through the ceiling. It was the flexi rubber joint leaking because of onto the iso. Idiot plumber did the bathroom. A year later the unsupported shower waste pipe fell out of the trap below the floor and kitchen flooded. 🙂

Does that not beg the question, which I have tried to put (badly) is "why didn't the op's plumber use the correct flexi? In which case the op,s problem may never have arisen!
Using the incorrect flexi, in my opinion, is the cause of the problem and can be laid firmly and squarely as the plumbers fault. Irrespective of ptfe tape, etc.

Monobloc, you mean... One word with no k.

Yep, it is the plumbers fault if the flexi end wasn't compatible with the fitting it connected to.
But we don't know exactly what the flexi was used for, - if the plumber supplied it, or if it was part of a new tap mixer.
If it was supplied with a tap and was the type with flat washer connection, then plumber should have used correct fittings, so no blame could be put on him later if any leak occurred.
Personally I hate flexis and only use them if supplied as part of taps. I rarely see the point of them and they are a weak link

Shaun is always talking Monoblocks! 😛

 

[GH77]

If I'm supplying the monobloc then I always look for one with copper tails, not a fan of flexi
