Hi there,
RTFM would be the appropriate response if I hadn't already done this...
So, in a fit of enthusiasm I plumbed the whole of my new extension last weekend. It's a single room with 2 radiators, one at each end. These are plumbed with 15mm copper pipe, and I also laid an extra 2 pipes from the kitchen through to the far wall in case we ever want a basin, washing machine etc.
Was very pleased with the result until I actually read a proper plumbing guide rather than the rudimentary instructions I worked from.
I used solder ring connectors, and no flux at all throughout.
My instructions stated that the joint was complete when the solder boiled and started to appear. So I basically blowtorched each joint for ages (15mins!) until a bit of solder came out. On a couple of joints, at the solder ring a weak point developed and solder burned through the copper! I made sure any hole was patched with solder. All joints feel secure.
I did 25 separate connectors, all very consistently as above so I figure the behaviour will likely be the same throughout.
So the question I have is, what do the experienced plumbers on here think will happen if I pressurise the system?
This weekend I'm working on it again, and am wondering whether my time is best spent making a temporary test connection to the mains cold water to test pressure, or just going around every connection with some fulx and run solder around each connection as if it were a plain copper connector.
Anyone got any experience to bring to my self-induced uncertainty?
Cheers,
Alex
