My friend has got a leak in a 3-way compression joint on a stainless
steel pipe.

The joint is for the hot-water pipe to the bath.
It is a 'reducer' type - large diameter pipe in, large diameter pipe
to the tap and smaller diameter pipe out.

I'd like to replace this joint - or at least the washers.

I have 2 questions :-

1) Is fitting a compression joint to stainless steel pipes any more
difficult than fitting one to copper pipes?

2) Given that these pipes are ~30 years old, will the pipe diameters
be 15mm & 22mm or 1/2" and 3/4"?

Thanks,
Mark.

Hi,

I don't know if this helps, but our house is about 30 yrs old too, and
plumbed enitrely out of Stainless Steel. I found ours to be Imperial.

The 1/2" and 15mm fittings worked inter-changeably without any problems.
The 3/4" and 22mm stuff was a little more tricky - needed a bit of filing to
get the olive and fittings on - but it worked OK.

I had to use compression fittings everywhere when I replaced the Radiators -
did a bit of research soldering Copper to Stainless Steel and thought
better of it !

Didnt have any problems with compressions fittings, I tightened them up
until they let out sort of a high-pitched squeeking noise, then stopped.

Cheers,
Tim.
