More than likely ChrisR watched a few and decided he'd fix his neighbours lead to copper pipe leak for a crisp tenner.
I can't understand the mentality of the few on here who constantly try to put others down. Pointing out that soldering copper to lead is illegal, does nothing for the trade plumbers are in. The phone goes at 6pm on a Sunday evening,,,,,,,,,,,,,,
" My incoming waterpipe has sprung a leak, Can you come round straight away?"
Plumber gets there and realises he doesn't have a leadlock fitting on him and can't get one till Monday morning. What's a man supposed to do? Turn the water off and leave them till morning? Leave the water on and let their house become flooded?.
Nah,,, a real plumber would do exactly as Tomp shows in his informational video and leave the customer pleased that they at least have water for bathing etc. Then call back round in the morning and do the job properly.
ChrisR would probably answer the phone and say he was too busy to go round, or politely ask them to call a real plumber.
As the old saying goes.
Those who can, DO,
Those who can't TEACH.
No wonder he's working at the local college doing assessments.
