Im getting the feeling someone is on a wind up with you guys
If not i wish i was a fly on the wall when the work starts
actually to much risk to be in the house
If its not a wind up my advice is get a plumber and ask him to show you how to solder e.c.t
I have had so many friends call me and say
jay help i cant solder or my waste pipe is leaking
when i get there they say "but it looked easy when i saw you do it"
a little water was still in the pipe on this one
