today’s plumbing adventure is it is it Rinnai. I’m taking over this job.I don’t know who did it I don’t know why we have a new heat exchanger here so we got to do some research on why there’s a new heat exchanger and it looks like it’s a burnout or something so give me a minute to try and figure this out and we’ll see if we can get some hot water – I know what this is – it must be – the hands sinks thinking it looks like this tank is in addition to this tank they’re working together they have this off hot and cold so I’m gonna turn it on and see what happens I got a felling that’s gonna leak right there right there baby a lot of corrosion in there who knows if we’re gonna get this baby running this thing’s nine years old I’ll shut it back down that’s why there’s a new heat exchanger.
