fagor water heater safety valve dripping

[charlie2009]

I have a apartment in portugal that has a 100 litre electric fagor water heater.On the cold feed pipe there is a sprung loaded safety valve.Once the water is heated up the safety valve starts to drip.normally when the taps are turned on in the apartment.This heater was installed around 12 months ago along with the other apartments,which also have the same problems.Any info would be welcome.

I would say based on what I know about Fagor and the French system, its not a problem, its designed to relive any excess pressure generated when the water heats up, I know the combined shut off valve/non return valve/safety valve, as a groupe de securitie, the GdS should have a trap with an air break between the trap and the GdS, with a waste pipe that leads to a drain this will or should let any excess water let by because of the pressure build up run to waste

Is this what you are looking at ?? its a GdS

Thanks.The gds is what we have.When the heater was fitted they never bothered to fit a overflow pipe to the waste,so its dripping into a bowl at the moment.Another job to sort out!!!!!!

This is what you need, just the trap not the GdS shown in the photo as well, the enlarged tail of the trap will take 32 mm plastic, and the waste needs to be run to the soil stack or drain

The overflow part of the safety valve does not have a thread on it.It just has a lip on it.Will the kit still fit?Thanks

Charlie,

I am sorry I don't know about the Portuguese type of GdS only the French type, but would assume that they would all be the same

I can only surmise that the GdS is not complete, the French models have a white plastic air break with a threaded tail, the trap has a deflector ( a circular collar, with two cut outs) that screws into the tail of the GdS,

The deflector snaps into the actual trap, its a circular disc with a female threaded inner portion (that screws onto the GdS with a spider grid surrounding the threaded part, and the two up-stands on the outer edge, with a lip for the trap to snap on to it

Hope that this helps you
