Hello All,

I'm looking for some advice on repairing my Silvano Evo. Recently, while backflushing, water started pouring out from the frame of the machine, and upon removing the case I discovered that a brass connection for the water line had sheared. I don't have a local repair shop, but the repair looks relatively simple, provided I'm able to source the part. I've included a photo if the damaged connection and would love it if anybody can point me in the right direction, or provide some advice for doing the fix.


*EDIT*I should add that the connection fed into the nut in the picture.

I'm not certain, but that looks like the priming valve.

Pump? OPV? Check Valves? Wit's end!

Chris Coffee's parts/service team has always been very helpful for me in making sure I got the right part without buying what I didn't need.

Thanks for the info! I'll look into it and contact Chris' coffee. Also, I should have noted in the original post, but this valve is downstream of what appears to be the pump, if that helps with diagnosis at all.

I've confirmed from a parts diagram that it is the quick release air valve. Thanks for pointing me in the right direction!

I can only find one half of the broken connection in your pictures. The only issue I see might be removing the other half of the broken piece which is what I can't find, assuming the part in the first picture connected to the tube with a ty-wrap is the broken piece.

Jeff had it in the first response. The "bubbler" side of the priming valve was broken off. Jeff even included a link to it on Chris Coffee.
