Strange sized WC inlet connector

[plummet]

So now I'm confused. I'm fitting a new WC and want to use a flexible tap connector to the inlet - but a 1/2" tap connector is too small (just) and a 3/4" connector is too big! I've heard that there is also 3/8", but unless I've really forgotten to do maths then that's smaller than 1/2" anyway.

Any idea what size connector I should be using?

Thanks

Not really.

Take the water inlet to a plumbers merchant or change it for a 1/2 inch one.

Where did you buy the WC from? I've fitted one for a customer who bought their WC from Bathstore, you should have an adapter that converts the 3/8" to 1/2". Its usually a plastic fitting.

Usually the hole for the water inlet is smaller than the standard 1/2", it just won't fit.

No vinny, he said it's too BIG.

With Bahco on this one!

How is the OP measuring his tap connector and fittings, bearing in mind the thread sizes refer to the bore of the pipe, not the overall diameter of the thread?

1/4"BSP is about 1/2" OD
3/8"BSP is about 5/8" OD
1/2"BSP is about 3/4" OD
3/4"BSP is about 1" OD

I have encountered some oddball pipe fittings (made in poland IIRC) threaded M16 X 1.5mm pitch, which is neither a standard pipe thread or a standard metric thread.

Thanks everyone for the help so far - impressed by the great support!

So funnily enough it is from Bathstore, as per Vinny's reply. I'll have to look later whether there is an adaptor in the box - I didn't spot one.

Still confused though...if this is the solution then that means that a 3/8" fitting is larger than a 1/2" fitting!!!

had a similar thing a few weeks ago, the original inlet had a plastic connector on whic had split!

Easy solution (and quickest): throw the inlet away and buy one that conforms to British sizes. Saves loads of hassle now and in the future!

When I fitted one it wasn't in the box, my customer went back to Bathstore where they handed one to him....maybe worth a try.

So just to complete the story, the reducing adapter that converts to 1/2" was indeed in the box as Vinny suggested - I should have checked more carefully. Thanks all

Nice one.

I'll remember that one.
