I am told that the mains water supply pipe entering my house is an old type alcathene pipe (about 22 mm OD). How do I connect a metric (22 mm) compression fitting to it? Can I use Hep2O pipe inserts for 22 mm pipes? Can I use 22 mm olives or do I need 3/4" ones?

If it black alcathene then it will be imperial, also there are different types or classes of pipe C & D were the most popular.
Cut a section out & take it with you to the merchants, you will need a special fitting for it as well as an insert for that class of pipe, you can't just use 22mm conex fittings on it.

Thanks very much, Keego. It is black alcathene indeed.
