hi, i am new to the forum and hope someone can help me. i have a ariston sx 20 mffice eurocombi which is leaking water from the stem of the divertor valve (just beneath the diapham housing and the ports) there are 2 grub screws holding them together so they do come apart. does anyone know what type of seal is in between the 2 parts? ie o ring or what?
thanks duckman
 
There are small O rings on the mains water side and a large O ring on the heating side. You need special tools to remove the smaller O rings. Best to replace the whole valve with a genuine Giannoni.
