The reason I don't use flexis...

[MP plumb]

nope, im still not convinced, u lot r too old skol. nout wrong with flexis. ok, they may not last potentially as long as copper but they are so so useful in areas where you cant reach, or pre- pipe taps, etc.

dancinplumba and I will marry one day, ur all invited, but instead of throwing conffetti, you have to throw plumbers mait at us (yer, its sticky and messy but i think plumba n i will love it), and our rings will be made of hardened LS-X, so it fits our fingers perfectly.... oh, and my dress will be made of thousands of taps of PTFE tape

perfect, just perfect
what a dream boat!

Only place I see flexis as being the only method is for back to wall toilets.

ive just seen the newer posts, yes there is more possibility that the tap will move if it is on flexis, but the tap should be tightened enough in the first place.... it doesnt matter about what connection is beneath it

Claire, save yourself a fortune and just get married in PTS.

Being so called "old skool" means we've been around long enough to know better.

Copper pipe adds to the strength of the tap, so helps prevent it turning. Plastic or flexis do nothing.

My opinion is copper is best and that flexi's and plastic present a comparatively increased risk of leaks. But I don't know what that risk actually is and I don't think anyone here does either, personal experience or not.

I also think people are inclined to defend their usage because they want to use them. We should treat those opinions we hold which we happen to want to hold with the greatest suspicion.

And so, given the fact I'm not skilled enough to use copper everywhere, and given the fact I do a lot of jobbing work where the clock ticks fast and you spend half your time under a sink or squeezed somewhere inaccessible, I use flexi's often and plastic ocassionally and work on the hope (not assumption) that the risk is small enough that I'd have to be pretty unlucky.

But the truth is it is a niggling worry and if I were skilled enough to be able to use copper everywhere in a timely fashion I'd use it everywhere.

So perhaps the answer is practise for homework.

Good post Watertight. May I suggest that you bend a supply of usable offsets suitable for a number of applications and keep these in your van as I do. Most wash basins can use a 60mm offset and if you bend a few right angles as well and some crossovers, you will have a ready made supply that will do for most jobs. You'll feel more satisfied with your work too. Use any medium size cuttings left over from jobs, it saves a lot of time and if you make these up in your spare time, it can actually become an enjoyable "chore" as well as good practice.

Solder/pre-compress any tap adaptors before connecting to the basin and you'll soon be flying through using copper as your preference.

Flexis are very useful sometimes, especially when piping up those awkward gas hobs..

good tips there system3

Lol! - Might as well add to the list of stupid, money taking things that we can register with! :smile:

you can only tighten a plastic jam nut so much,
plastic jam nut + hot water + flexi + hep2o= "hiya, remember me, you fitted my bath, well theres water coming through the living room ceiling"
we used to keep brass jam nuts from 3/4" ballcocks and swap the inside one for plastic so we had brass for the taps, and thats with tap adaptors and copper

System3: i know where ur all comin from, but i just dont trust fibre washers... sooo many times ive come across a copper tap connector with a broken fibre washer, or LS-X, or mastic all over it, or its been cross threaded...
a great example to use a flexi is when u have to replace an old tap with a new one and the new tap has a longer thread than the old, so you have the option of cutting the copper back and putting a new valve(which so often isnt there) on and a flexi because there isnt space to solder a copper pipe on with out burning the wall or the bath.
and often, the pipe has already been bent to suit the old so ur already struggling to find a long enough lenght of copper that you can connect to.

I used to use alot of plastic pipe a flexi's when I worked for a firm and they supplied us with materials for a job, and sometimes it will just save you alot of time to use it. Now I am self employed I use copper 99% of the time, but flexi's and plastic can get you out of trouble at times. I have managed to feed plastic through under fully tiled rooms by lifting a board in the rooms either side etc, same for expensive wood flooring. This would not have been possible with just copper.

Copper pipe adds to the strength of the tap, so helps prevent it turning. Plastic or flexis do nothing.

what would you rather change, the inside bath tap that is onto copper with FI adaptor and red stag, or a hep20 pipe and flexi (ok we know what is easier to change, but the flexi has only been in for a few months and the red stag for 30yrs thats the difference)

i dont think Whn1 knows what were talkina bout...
but im fighting my corner... im listening to what ur all sayin.... but id love to see u try getting into the tight spaces ive had (jokes aside) to and try soldering a pipe or not use a flexi...

Why do you think you get in tighter spaces than the rest of us lol???

the space between a wall and bath hasnt changed much over the years, ok it used to be about 2" and now its about 50mm, but the blow lamp and pipe slice still fit in

 

[MP plumb]

whats red stag? :s

i use copper for all of first fix, but i beleive flexis are fine to use when it comes to basins, baths and toilets.

what do u guys use when u have the toilets thats u have to connect to the water before pushing them back to the wall? flexis....

thats not always simple of cost effective... in my opinion... expesh the side thats closest to the wall

coz i have boobs!!!!!

Claire. we've all seen incorrectly installed fittings of all types, including those that use fibre washers, but that is the fault of the installer and not of the material. I fault flexis as the material not for those who install them.

Copper will outlast flexis and plastic and that is why I prefer it. As professionals we have to be a cut above the diy brigade and I take more pride and satisfaction from a installation using copper.

By the way, most washing machine manufacturers recommend changing washing machine hoses every 5 years, so where does that leave flexis?
