Compression fittings

[rocketmanbkk]

Does anyone put compressions under floor?

I understand it's better to solder

How about if connecting to chrome pipe or no space

Thx

Sand of Chrome and solder if possible.

Thx.

no tbh your asking for trouble (you only need one to go) and as above sand/file a decent amount of chrome off eg half an inch above said fitting

I go to any amount of bother and time just to use solder fittings everywhere, especially below floors.
Only exceptions are somewhere that in the future you need to disconnect the pipes, - like last connections to a monobloc mixer, or heating pipes crossing over and in front of a cylinder.

Yes I've done it before as a last resort on a system that kept releasing water and wouldn't solder even after full drain and wet vac although if theres ever a problem its only under carpet not tiles or laminate

I try to use copper and end feed fittings all the time. I use compression if I have too such as 3/4 pipe etc. That said I've done some jobs recently all in push fit as that's what's on the job spec.

The only reason not to use compression all the time is cost and they're very time consuming.

Been to about 5 weeping solder joints in the last week. A compression joint on smooth pipe with good olive with ptfe/paste and not over or under tightened is going to last long enough not to worry about. Maybe it'll be a risk after 25 years instead 100 for it's soldered buddy but that's good enough for me. But as Leo says, much more time consuming. Push-fit however....

It's no wonder soldered joints leak. I don't think many plumbers actually know how to solder properly tbh. Makes me ashamed of the trade

Nothing wrong with high standards. But doesn't qualify everything below as low standards.

Sometimes I feel like a plumber who is vocal about their high standards is a not too distant cousin of a jobsworth, albeit given legitimacy by the threat of collapsing ceilings.
