that's a good point, Ben, so far i don't think my opv has been acivated ever! the vinyl hose that leads to the drain pipe never looks wet inside. it should be a backup so your boilers expansion from heating up. i am useing a Swagelok relief valve to replace the stock unit everyone has problems with, but the newer Brewtus's have good opv's. my machine was one of the first sold.- Dennis

Do you use a rotary (plumbed in) pump, or a vibe pump with reservoir? If it's a vibe, the drip tray holds more than the reservoir, but I'm guessing you have a rotary. You said, "...it fills up too quickly if the OPV output goes there"--which leads me to wonder if your pump is setup correctly. I just learned a few days ago that it uses a different paradigm than the vibe pump, and if properly set, it shouldn't drain anything out of the OPV under normal circumstances, right? I'm not totally sure on this--but the new directions from Todd last week had me set the OPV to 11 bar, and the pump to 9 bar (or preference). When not in use, the system routinely gets up to 10 bar, but so far doesn't get to 11 and therefore hasn't opened the OPV at all that I can tell. ??? I wonder if bumping your OPV up would solve your dog bowl problem, i.e. overfilling. b On Mar 22, 2011, at 5:37 PM, Dennis wrote: > that's a pretty tricky way to kill two birds with one stone! i share the > clothes washer drainpipe, so i am lucky enuf to have plumbed drain and my > opv water goes into the same drain. > > -----Original Message----- > From: [email protected] [mailto:[email protected]] On Behalf > Of Bruce Keeler > Sent: Tuesday, March 22, 2011 12:51 PM > To: [email protected] > Subject: Re: Boiler Descaling > > Ooh, I like this idea! > > Though my brewtus already caters to the dog's needs.
