Soldering under floors

Postby alanjacobs » Sun Oct 19, 2008 2:43 pm

Hi, silly question ... but how do you solder joints under floors?

I have restricted access which means I have to point the blow torch downwards but whenever I do this the torch flares and blows itself out.

Are there better torches out there that can work upside down?

Mines a Bernzonmatic butane/propane.

as the can enough gas have you tried tilting the can at a different angle and is it strong enough
failing all this can you not use push fit connections

some times the torch just needs to warm up so burn it for a little while and check... also very new full cans will do it more than emptier ones and try starting with a gentle flame... open as you need

Mines a Bernzomatic (88230 from Screwfix) and it works fine upside down, or indeed at any angle.

benzomatic torches can work upside-down so if it's extinguishing then either you need to open the gas valve a little more or there is not enough gas in the bottle. unless your torch has a fault.
