Main supply reducer.

[Burro]

Hello,
I need to remove the very old tap that (used to) close the main supply of cold water.
The pipe is not in copper (to be honest I dunno what is made of).
It' a 22mm pipe and I am thinking of reducing it to a 15mm.
Any suggestions??

thanks
Burro

Leave the old one in situ and put a newer one 12 ins away.

the aim of my post is to remove that tap as I am fitting a corner unit so it must go.
I was reading about Dielectric Union, but if I cut the "iron pipe" would i still be able to fit it.

ps congrats.. I haven't touched a fag for 5 years and I feel great.

Thanks
Burro
