Hello All,
I'm fitting a new bath and wanted to use flexi connectors for the taps.
Only snag is, the system is gravity and it seems that 'full bore' flexi hose is actually about 14mm, not 22.
If I use a flexi, do you think that will have a drastic effect on the pressure from the thermostatic mixer tap I'm putting in? The water pressure to the current mixer tap in the bath is already pretty feeble.
Far as I can see, there's no such thing as a truly full bore 22mm flexi... Is there?

Thanks

No there isn't. What is supplying cold to the mixer tap? If it is mains then it won't work properly. If it is tank feed then do the same to both taps and the flow/pressure will be equal.
 
you can get 22mm copper convoluted pipe, which is flexible enough to wiggle it up your taps. You can bend it to shape in your hands.

It's shaped a bit like a vacuum cleaner hose.

That's called 'plumbers stick'......quite handy really but some will no doubt disagree. Its thinner than the normal copper though and doesn't like a pipe cutter.

Why do you want to use flexi's? Is it for ease of installation? If so then use plastic with push fits, it will give you a degree of flexibility over copper whilst retaining the bore for maximising flow, fit it all together prior to clipping.
 
Copper all the way with solder ring fitting for maximum flow rate possible and give extra support for taps.

I never will use flexible pipe connector any where.

Thanks all. Main reason for flexis is that the hot and cold are the wrong way round, so it seemed easier to put flexis on. Until the tap arrives, I don't actually know if I have a problem there but I saw on the web that with thermostatic mixer taps, they actually regulate the amount of hot water, not cold, so I thought I might need to redirect the supply pipes a bit under the bath. Flexi seemed a good way to do that with minimum fuss.
@Madrab - yes I think plastic push fit will best as you say, it is full bore and I can redirect the supply pipes more easily if I need to due to it being a bit bendy.
When you say "fit it all together prior to clipping" - what exactly do you mean - clipping to the wall..?

Wavin list a 3/4" x 22mm Flexible Tap Connector as "Full Bore" their part no. Is HD225c/22w Hep2o x 3/4" BSP swivel
 
Thanks, but looking at those, it seems to me that the diameter of the braided/flexible pipe bit is pretty narrow... I don't think they're 22mm from end to end.
However, it's not a problem - I plan to use plastic/ push fit as they're easy to manipulate, join etc and I can maintain full bore for more of the run.
 
I would be very surprised if they weren't "Full Bore", I can't see a company like Wavin claiming something like that and not actually delivering.
I would imagine they would be pretty pricey and would be tempted to use a 3/4" x 22mm Hand "Titan" one piece tap connector with a length of plastic pipe.
