    Re: Boema

    Gday Maurcicem,
    the pipe at the bottom of the pic goes to the steam tap, the pipe at the top terminates into something that looks to be spring loaded. :-?
    Thanks,
    Steve.

        Steve,

        you beat me to it...I was going to ask if the pipe at the "bottom" (of the picture) goes to the steam tap.!

        So what we cant see is that the hole with something missing out of it is actually a "4 way" fitting screwed into the top of the boiler with facility for:

        a) the safety valve for the boiler (as in "over pressure release")...which is the part of the fitting going off in the direction of the top of the photo

        b) the steam "take off" to the steam valve...which is the part of the fitting & pipe going off in the direction of the bottom of the photo and

        c) the fitting which is missing from the threaded hole...which will most assuredly be the ANTI VACUUM VALVE (unless you find an anti vacuum valve elsewhere on the top of the bolier, in which case you better take another photo showing us as much of the top of the boiler as possible so we can try and work it out).


        An anti vacuum valve is a relatively cheap part (around $20ish) that should screw straight in to the hole.

        Why would anyone remove it..?

        They are a relatively ineffectual device at worst because they get blocked up with calcium coming out of solution in the steam, and get blocked shut therefore not continubng to operate as an "anti vacuum" valve.

        Very often they leak (hiss) steam continually.......this seems to upset some people but I can assure you, its nothing to worry about as the machine will always produce a ton more steam than could ever leak out from a pissy little leak like you get from this valve. They are very easy to manage. To stop the hissing, you simply hit the nipple in the top of the valve with a screwdriver or back of a spoon or anything, and this knocks it in, then it springs back up, usually re seating itself and it stops leaking.....until next time.

        Screw one back into the hole using a bit of plumbers tape...at worst you can blank the hole right off with a threaded bung (as long as you remember to always de pressurise the machine by opening the steam tap when turning the machine off, & repressurise through the steam valve when turning it back on). Its the LEAST of your problems in sorting out what really may or may not be wrong with this machine.

        Regardz,
        FC.
