There is a rather sorry tale behind this accidental acquisition, but it is what it is. Here it is as found: Underneath all of that filth was a lot more solder than one might suspect; in fact even the pressure screw had been soldered down, presumably to prevent it leaking (not the first time I have encountered that!). So some determined cleaning and de-soldering was the order of the day. Once the filler cap and pressure release were melted out of their solder encapsulation there was absolutely nothing wrong with either, all that had been required were 2 new Viton seals
Hi Ian. @igh371 Looks to be running well. What is the best way to remove all the excess solder and how was it an accidental aquisition? Regards Jeremy
Removing excess solder Jeremy, if you are lucky, just heat until softens and then wipe off with a damp cloth; things get a bit more trying though if there are other fittings nearby that need protecting from the heat But as to the 'accidental acquisition', lets just say I went for something else which was grossly misrepresented …
