Flexible tap tails All aspects of plumbing questions and answers, help, tips and information

[Spanner]

Just bought a new monoblock basin tap which has come with flexible tap tails with 3/4" end (female). Currently the cold water comes off at a tee to the tap, then goes on to feed the WC, the hot pipe goes straight to the tap fitting(previously had a 2 hole basin). What specific fitting do I need to add to the hot and cold pipes on the already existing 15mm copper pipe to be able to connect the two together?

Spanner,
Sounds like you have bought a bastardised tap, 3/4 is most unusual. It will probably be easiest to buy some new flexibles but take the ones supplied so you can match the thread into the tap.

Thanks Stoeyboy,
If I bought new flexibles what size ends should they have and what fitting would I need to connect them to the existing pipes?

Are you sure they are 3/4" and not 22mm? I presume you are trying to connect to the existing 15mm supply?

If so you can use a 22mm straight connector with a 22 - 15 reducer kit in the pipe end.

Personally though I'd take them back and say "these are no good for a 15mm pipe" and get FOC replacements if you've only just bought them.

Cheers

Spanner,
You should be able to buy flexibles which will go straight onto 15mm copper either with a push fit or compression fitting.

Why the hell should he have to buy new ones if the ones supplied were not fit for purpose? Take 'em back and get them replaced.

However, if he's stuck with the ones he's got using a straight compression connector with reducer is going to be cheaper for him than buying a pair of brand new flexis.

Thanks Rosebery,

Actually I think they may be 22mm, I'll give it a go.
