How do i connect up an exterior sillcock, it is abou 8" long and has a
male threaded end. Inside the wall it is just a copper pipe that runs
perpendicularly towards the exterior wall. Do I cut the pipe and buy
some sort of adapter? Will there be a problem with the dissimilar
metals? My pipe is copper (i think) and the sillcock is a shiny chrome
type finish. Do I then solder this? If I have to cut the pipe, is
there an easy way without full access all the way around the pipe? The
pipe is along a wall and I've only got access from one side. Any
advice? Thanks.

Get a mini tubing cutter like:

You can pull the copper away from the wall
enough to use it.

Yes, you need an adapter. One end will solder
to the copper pipe. Assume the pipe is
1/2" trade size (5/8" O.D.).

The other end of the adapter will have female thread
for the sillcock to screw into.
Sounds like a "frost-free" type. Many of those have
3/4" male pipe threads. Bring the sill cock to the
store to be sure you get the correct adapter.

You can get adapters in either straight or 90 deg style
for whatever fits your layout:

Most of the frost-proof sillcocks I've seen are visibly threaded but
1/2" copper fits inside. You can go either way depending on your
preference.

I agree. The ones I've seen have male pipe threads but also are made
so 1/2 inch copper pipe will fit inside for a solder joint, so you can
go either way. If you go with the pipe threads, then you need an
adapter which is female threads on one end, solder on the other.

Thanks for your replies. I'll attempt this over the weekend. I'll try
the mini cutter, if not I think a very small hacksaw can get at it. Is
there such a thing i can get?

Thanks

The frostproof sillcocks work with both 1/2" copper and threaded
connections straight out of the box. This is almost certainly what you
have, right?

There's no need to cut it and cutting it will almost certainly turn it
into a paperweight as the valve seat is all the way at the back of the
sillcock near the threaded end you want to cut off.

It's possible you have an older type, but unless you know exactly what
you're doing, don't go modifying a valve. If you have one that is only
threaded, get an adapter.

I think he's talking about cutting the 1/2 copper pipe leading up to
where the sillcock is going to be installed.

For once I certainly hope I misread that! Thanks.
