Hi Dave Not necessarily, could be galvanic reaction due to dissimilar metals, or electrolytic if you have some stray electricity grounding to the pipes. (seems a common problem with pumps or if you have "earthed" to the water pipes). Particularly bad in water with a lot of dissolved solids, that will remove the zinc coating very quickly. Galvanised fittings on steel pipe can be worse than plain iron fittings in certain circumstances. 304 stainless (passive type) or 316 stainless are much better. All the fittings we used to make had to be to the appropriate standard, those for potable water had to be approved by the UK water authorities and all had to carry the BSI Kite mark. Those approvals still apply and anyone found importing, selling or installing non approved fittings could, in theory, be prosecuted. Seems nanny state, but not if your house floods, your boat sinks, or your sprinkler system fails ;) Steve Blackmore -- ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
