hi I bought a house with speedfit plumbing , mainly their pipe , few compression fittings used too.
Not sure how old it is
I noticed on all the fittings the threads we’re slightly loose.

They weren’t leaking, but are they just working loose from slight vibration of the water flow ?
And are they generally safe ?
Thanks
 
Hi yes they're generally safe, is it the compression ones loose or speedfit?
 
If I have to use pushfit, I prefer the newer Speedfit for ease of installation and adjustment (without the need of a removal tool).
The compression factor also adds a layer of protection and enables removal of inserts from the fitting, for when they come off the pipe during modifications.

However, I have come across many that have not been tightened up by the original fitters (I've always believed this to be because the original JG speedfit just pushed on and those using them failed to adjust their install procedure for the newer "compression" versions!).
I've also seen the compression "nut", on a fitting, become loose/unwind when manipulating a length of pipe attached to it, scary if that fitting is in a space, hidden from sight!
I've always thought that they should redesign the compression nut so that it clicks and "locks" in position when tightened up properly - should be fairly simple to achieve this design-wise.

Locking "collets" are available but they're, yet another, fiddly component to have to procure, stock and carry with you!

Hep pipe and fittings are far superior IMHO..

But you end up with a box full of fittings with the metal insert still stuck in them and trying to remove them damages the o ring! :p;)

Why...use removal tools...No worse than speedfit...Pipe much more flexible..Fittings less bulky...non of that tighten loosen caper
 
Thanks, I’ll get some of those locking collets to be sure they are safe.

Removal tool still leaves the metal insert in some of the fittings... Anyway, I'm not saying one is superior to the other, just my preferred product, "if" I have to use them... I have to use them all as they are often specified without my input!
