Michael Posted February 8, 2008 Share Posted February 8, 2008 Yes on compression ,If you are connecting up a Cylinder or Boiler I would run the first metre or so in copper or as in manufactures instrs. Michael Link to comment Share on other sites More sharing options...
tj Posted February 8, 2008 Share Posted February 8, 2008 HiCompressions are ok, if it makes you feel more comfortable, fit a pressure reducing valve on the mains inlet ( 25 euros ) they are preset to 3 bar more than enough for the average house.

BIG MAC Posted February 9, 2008 Share Posted February 9, 2008 compression is fine just make sure that you lock the olives to the pipe? righty tighty then a tweak. I use PTFE tape these days to wrap the olives rather than BOSS white or water hawk. Due to cost I would only use compression fittings in areas where heat could damage surroundings I prefer to use end feed. Link to comment Share on other sites More sharing options...
LesFlamands Posted February 9, 2008 Share Posted February 9, 2008 Pressure reducers are required by regulations for chauffe eau installations but a good idea on all installations, even if the incoming pressure is low it can vary quite a bit Link to comment Share on other sites More sharing options...
P3 Posted February 9, 2008 Share Posted February 9, 2008 Cannot remember the name of the English fittings but, many years ago when I was a fitter, I used fittings on pipes that supplied 3500 sec oil at 300 degrees F and 300 psi with fittings whereby you placed the nut on the pipe, as per compression joints, and then inserted a tool in the end which, when you turned it, a ball bearing was forced out. This created a ridge in the pipe. When you did up the nut this ridge was flattened to form a sort of flange and a very secure joint was made. Think they mught have been called 'Klingerite' or something.Paul Link to comment Share on other sites More sharing options...

Will see how good some of my colleagues memories are tomorrow.Paul Link to comment Share on other sites More sharing options...
