Plastic Compression Elbows ("speedfit")

compression will blow if it freezes, what makes you think you think it won't ?, theres nothing wrong with using speedfit common sense would tell you to lag it in a roofspace

Sorry first of all but I have no faith in speed fit or the like...I just feel better putting in the effort and using a comp fitting....

After all if a job's worth doing it's worth doing to the best of your ability everyday

if you actually follow speedfit mfis to the letter, your supposed to pump the sytem upto around 10 bar from memory for about 30 mins, long while since I did it, in order to get the steel rings to bite in and grip. If the fitting fails the rep pops round cuts off the failed fitting for a bit of an inspection, no grip ring marking no payout. The problem normally is the the plumber just pushes and goes. Used some on a buildings conversion I did, tested and pumped up 4 of the units, didnt bother to do the same with my own part of the conversion whee I live and months later who had a slipped joint leaking away!!! Always remembered to practice what I preached fm then on and no leaks to date
