Guys,
Was working at a house the other day where a couple of sections of 1" pipework had to be removed (for underpinning purposes). These have had to be put back. I used 28mm compression fittings to reattach the pipework together. Had a few issues getting the nuts and olives on the pipework but managed. Tightened the fittings but when I refilled I had several leaks (quite fast drips). I didn't overtighten and further tightening reduced the leaks but did not stop them.
I was unable to use soldered fittings as the pipework was wet, sludgy and furthermore needed a 1" to 1" solution not an 1" to 28mm fix.
I'd not encountered a problem with using 28mm fittings before and given how tight the nuts and olives were on the pipe I was suprised to see they leaked so bad.
Any advice on how to rectify this would be appreciated, thought of PTFEing them but not sure that this is the best solution. Any advice on the best way forward or most suitable fittings would be appreciated.
