So it turns out we've been doing this plumbing lark all wrong,
Spending money on flux solder blow lamps and gas all's you need is a bit of silicone and some tape!
Went to a call out where there was a leak on gravity fed system when the boiler is on,
I found under the floor a tapped and siliconed up tee,
First I thought it must have a pin hole or slight crack on the joint, but after draining down I was wrong
The straight part of the tee was soldered all fine, but the branch was just pushed in and silicone smeared round then tapped up...
