But from past 1week we notice that after switch off regulator still the gas was passing to burner, so I've contacted to my hp gas service center they said we will send mechanic he will help you, then he came to house and checked all the things is good but there is problem in regulator and suggest to change regulator, so i went to service center they ask me to pay some 236 amt for replacing regulator. But how should I pay money if i have already pai 250 on December month after a in just 3 month it start getting problem.. So is it my problem to pay money if regulator is not working properly.. One more thing there is no sign off any broken area on regulator.. Help..
