ripping a bathroom out today and removed some pipe i assumed was threaded iron , all painted up. but its actually very thick walled copper and brass fittings , never seen this before, anybody else seen this ??
Did one before christmas, got some comp reducers. That was thick walled od was 16mm the reducers were £4 each house was built in 1936.
Tom you beat me to it....... at £4 per kilo, it would be in the back of my van and off to the 'recycling centre' pronto DH
Fairly common on Hot water systems in old houses(circa 1900-1930), fine threads screwed into brass sockets & EF soldered. Just imagine standing behind a CC/CCC in the merchants, when he asks for a JG fitting for it.........:^O :^O :^O
seen plenty in Manchester even had the pleasure or striping out a heating coil in 2 inch screwed copper years ago in an hospital cloak room ,,every one just though it was mild steel until we tried to burn it out and if that was not good enough we had the identical coil upstairs,, with the 16 17 mm if you have pipe ex panders with care you can expander bit of older pipe to make a socket,, or prestex make them
it's whats called 20 thread copper, 20 threads per inch . i work in a stately home and weve got loads of it. if you need to connect to the 1/2" size use a 3/8" bsp x 15mm fiiting. all other sizes you are stuffed unless you save fittings and braze to modern pipe.
