I have had maybe one PLA break int the tube.
Keep your PLA in a big zip lock bag with desiccant when you aren't using it.
And of course it matters where you are getting the PLA from. I have tried a few brands that just didn't work well. Sometimes they would print great, sometimes it would crap out. I think the Ultimaker brand PLA is pretty good. Right now I am sticking with PLA from 3D Universe, but they are in the USA.
There is a ridiculous number of materials out there now. Good luck with your search. It is worth it to pay a little more for something that doesn't cause problems.

Hi it would be useful to know what PLA you are using, manufacturer and type/colour; also what printer are you using. I have been printing for 2,5 years, probably 80% PLA and have never experienced a break in the Bowden tube.
