Hi Folks,

Ok so I want to try and do this myself but need some help - or its time to call a plumber, but I am determined I can do this.

Basically the bathroom wash basin taps are shot. Need replacing. However its hard pipe into them - I measured across (no calipers) and its seems to be 15mm. However it tapers into the taps with a reducer as far as I can see.

So my question is - how do I figure out tap sizes to fit the hard pipes into or will the bottom length variance mean its better to take off the hard piping back to joins and presumably do flexi 15 mm (female or male?) into a new set of taps ?

There are taps along the piping - so I can isolate while I do the work - excuse the state of it, recently bought house and bathroom is on list after a long list of other things!

You will I think find, that many modern taps use flexi pipes - stainless steel woven outer, to a flexible pipe, so fairly easy to just cut the original pipe and fit.

More important, is to find out whether you have a low pressure HW system (CW tank & cylinder), or a high pressure system (combi boiler). The taps need to be suitable for the HW pressure.
 
Its a combi but the pressure is rubbish - but noted.

So can I just remove that vertical pipe from that angle and replace that section with flexi and bolt it straight on?

Pressure is not the same as flow. You can use low pressure taps on a combi, though not high pressure taps with a low pressure cylinder.

More or less, yes.. You just cut the copper pipe length to suite, so the flexible has no kinks.

It’s not a reducer, it’s been done properly! Copper is proper (remember that :mrgreen:). So you have a compression elbow, 15mm pipe and it goes into a tap connector and seals using a fibre washer or sometimes nylon. Flexi’s aren’t the be all and end all and can actually reduce the output of flow. When you obtain your new taps, if they don’t come with fibre washers buy some they’re less than £2 for a packet of about 10. You just need to ensure you have removed the remnants of the old fibre washer - you can do this when the tap has been removed and look in the hole where the tap was. Oh, and you may need a basin wrench - that’s using either method.
 
So just to finish this off. My confusion was that there are different sizes etc so thanks for the help. Turns out i was being stupid - got some taps, used the existing fittings and new washers and viola that was it.

I couldnt quite get the nut underneath tap quite tight so need to sort that but no leaks
 
Since you mentioned a reducer, it's possible that the taps require a different size. It might be best to remove the hard piping back to the joins and use flexi 15mm pipes to connect to the new taps.
For the connections, you'll need to determine if you need female or male threads based on the taps and pipes. It's a good idea to take pictures and measurements to ensure you get the right fittings.
