FAQs

What sizes of copper pipe are common in UK homes?

15mm and 22mm are the usual sizes for domestic water and heating, with 28mm on larger runs and 8mm or 10mm on microbore heating.

What is the difference between end-feed and solder ring fittings?

End-feed fittings need solder fed into the joint by hand. Solder ring (Yorkshire) fittings have solder built in, so you only need flux and heat.

Do I need lead-free solder?

Yes for drinking water pipework. Use lead-free solder and a suitable flux, and flush the pipework after soldering.

Can I join copper without a blowtorch?

Yes. Compression and press-fit fittings join copper pipe without heat.
