3/4" Thread taps in WC / Utility Room?

[DIYNotIan]

Hi

I'm putting in a new sink and taps into a downstairs cloakroom / utility room. The sink is a reclaimed baby belfast, and I want some old taps to match. I've found some NOS pegler taps at a good price, but they have 3/4" thread.

Is this ok to connect to 15mm pipe? Will the flow rate be a LOT more than 1/2" thread? Any other potential problem in using these?

Many thanks

No ,flow won't be any different.
Will the 3/4 tail fit through the hole in the sink ?

All the baby befasts ive come across didn't have holes for taps, they were fixed to wall behind or came up through the adjacent work surface

So they are ,missed that bit

Thanks for the replies. And yes, we'll be having a piece of wood between the sink and wall and the taps will be fitted to that.

So, aside form the different thread size, there's no other difference or potential problems?

Cheers

Flow rate will be determined by the 15mm pipe anyway, can't see any problems if you use proper 15-3/4 tap adaptors

Excellent. I've gone ahead and ordered them. Thanks for the help.

Just an Aside
Are the NOS Pegler OLD washer low pressure taps , what supplies you hot /cold water
Cold at mains pressure will be OK - BUT hot from a tank with high pressure tapscan be an issue depending on the setup
I cannot find the NOS Pegler listed
I suspect its all OK if old washer style taps - But thought i would mention in case

Hi

That's an interesting thought - thanks for pointing it out. Here's a link to a couple of websites showing the taps and some details for them... Does all of that mean anything to you/anyone,. with reference to your point?

We're on oil, not a combi (we have a water cylinder).

Cheers

They have compression washers so should be ok for your low pressure hot water and mains cold

I was just thinking about this... If the flow rate is no different between 1/2" and 3/4" taps, then why are bath taps always the larger size? Is it because they are usually fed by larger pipes? If not, why aren't they all the same?

Sorry if I'm missing something blindingly obvious!

You have answered your own question . Historically , bath taps were fed from gravity fed plumbing systems ( a lot still are), so larger diameter pipes to baths . That allowed greater flow with the limited pressure. Obviously taps would need to be larger so as not to impede that flow.

Gotcha. Thanks for explaining / confirming
