This problem has been reported and analyzed in the commercial nuclear industry. Industry studies indicate that the formation of the substance does not significantly degrade the current carrying capability of the wire or insulating capability of the insulation. The main concern with the substance is dripping onto electric contacts. Routine inspections or maintenance of electrical components should determine if any of the wires … text/html 2008-04-17T22:06:27+01:00 http://www.diynot.com/wiki/electrics:lighting:downlights:firehoods?rev=1208466387&do=diff Intumescent fire hoods INSTALLING RECESSED LUMINAIRES IN CEILINGS by Bill Allan THE IEE receives a number of enquiries from designers and installers and others regarding the application of Regulation 527-02-01 when installing recessed luminaries in ceilings in domestic premises.

This is done via a silver braided pipe under your boiler in which the valve is opened to allow water through until you reach the correct pressure. More details here.

They are designed to let air IN to waste or drain system, so that siphoning does not occur. Such siphoning can “pull” the water out of a trap so smelly air passes upwards. They do NOT let air out. Individual fittings are available from 32mm diameter up, or they can be built in to a trap, such as this one - the little part which looks tacked on the top is the… text/html 2008-03-28T20:41:49+01:00 http://www.diynot.com/wiki/plumbing:automatic_air_vent?rev=1206736909&do=diff Automatically vents air from system whilst filling. AAV's have to have their caps left unscrewed for them to be able to let air out. They are used at high points in pipework where air could collect. Sometimes, for example in or near boilers, they MUST be left permanently open. When they get old they are inclined to scale up and leak water out, in which case they should be replaced. Note that when the cap is left undone they will let air in if the water is drained from the connected pipe, whic…
