There's a garden tap at our new house in the garden!

I've tried to attach our Hozelock 3/4" BSP adapter but
it does not fit. The tap thread seems to be very slightly bigger.

The only markings on the tap's brass body is what looks like a
BS kite mark and the text 'No2'.

Any thoughts as to what size it might be and if I can get an adapter
for my Hozelock? The Hozelock will also attach to 1" BSP so a
'whatever my tap to 1" BSP' adapter would be ideal.

TIA

Guy

I've come across smaller than 3/4" BSP on garden taps. I'd just put a
new tap on FWIW.

Have you removed the 1/2" BSP adaptor ring?

I've never come across a garden tap that wasn't 3/4" BSP personally. They
cost a fiver, replace it. Easiest option.

Sorry about the blank message - hit the send button by accident!

Are you sure that your adapter is really 3/4" BSP? The acutal size of BSP
threads is larger than the nominal size, as shown in
http://homepages.tesco.net/~A10bsa/bspgo.htm because the BSP size refers to
the nominal bore (inside diameter) of an iron pipe, so the thread on the
outside obviously has to be bigger than that.

Can you measure the thread diameter of your tap with a vernier caliper and
post the result here.

Most garden taps are 3/4" BSP (actual size 1.041")

Some are 1/2" BSP (actual size 0.825")

I've even seen some which are 5/8" BSP (actual size 0.902")

I'm now pretty sure the tap adapter is a 1/2" BSP in a 3/4" BSP
fixing and that the tap is not quite 1/2" BSP.

I think I'll be getting a new tap!

Could it be 5/8" BSP? You can get 5/8 to 3/4 adapters.

I'd still go for the new tap option FWIW.

Yup. I had. I did.

Fit one with a check valve built-in if you don't already have one in the
pipework.

Could be, but very rare - especially in a new build?

The havn't sneaked in metric taps without telling us have they?

It is already an EU requirement that we only use metric threads, which is
why BSP is, officially, a metric thread.

The house is 1935 but with a 1990 extension. The kitchen was done
in 1990 and it's possible that that's when the garden tap
was fitted.

I don't think so.
