Hmm, then, new single piece pipes would be better to avoid leaks from joints.
Thanks man.
I hope he fills proper gas and charges it well.
And one more question,
He is charging me 2000 rs. for day22 kagho gas and vouch for it. While when I asked him to install honeywell, he first complained that this is not available readily, many mechanics will fool u by filling chinese gas in honeywell named cylinder, I will charge 3500 rs. for it. So guys, is this kagho gas good enuf?
