Or, sometimes it's the little things....

This tiny (<1/2") ferrite impeller broke in half, reducing our brewery's ability to make hot water by 1/3, which means taking half again as long to make beer:

I was able to glue it back together w/cyanoacrylate glue, which lasted for two days:

Of course, I can't just replace this little bit of magnet, but have to replace the entire "water control assembly" at the cost of $80. Rinnai on-demand water heaters are a PITA.

And, of course, Rinnai's distributor won't sell directly to me so I have to go through our propane supplier. Three days and still waiting for the parts....

Protected dealerships.  That's the way it goes.  You probably remember when it used to be worse, like if you wanted a head gasket for a B&S engine you had to go to an authorized Briggs dealer, or no dice.  Or, when VW fuses could only be bought at a VW dealer.  The good ol' days.

You would have to notch it so as not to reduce side clearance, but I'd want to glue and wire it together.

I got three full water control assemblies today, at $81.50 each. I'll try the wire trick for a back-up. I had no idea anyone else here would have torn this deeply into a Rinnai water heater!

BTW: These things suck. I'm running three C199s to heat a 1,200 gallon tank of water, several times a day. They under perform as advertised, and can't handle a water hardness (160 ppm of carbonate) that was advertised as within tolerance. I clean them constantly, and replace parts at about $200/year each. Not impressed.

Remember, I'm a commercial user. For home use, you likely won't put as much water through one in a year as I do in a day--unless you have teenagers. But the units I bought were advertised as commercial units.

Find some old standing pilot Palomas. Guy I knew had a laundromat/ car wash and ran 2 of these on the laundry side.  Exceptionally tough units, he had a water leak under the slab and these units ran 24/7 for at least two months straight. One stuck the actuator valve for the gas which was an easy fix, the other one shrugged it off as if nothing had happened. They were a couple of years old when this happened and soldiered on for a few more years until the new owner did a total remodel on the place. Our water has a TDS of 400+ here. The Bosch unit in the car wash was crap and difficult to get parts for. I resealed a Takagi for a restaurant and I was not impressed with that unit either.  I wonder if yours are underperforming because of your altitude?  E.

I would suspect that part is part of a flow measuring instrument, and it trips a field effect semiconductor for counting revolutions. Adding metal to it might affect the counting measurement. Close monitoring might be needed for a while.

Thanks for the ideas, all.

Eric: Our units are set up for our altitude, so supposedly that would make no difference. The main difference is between claimed and actual performance. Salesmen have a funny way of twisting things. For instance: "You can expect about 9-10 gallons/minute throughput." Is absolutely true--as long as you're not heating water. Once you start calling for heating, the units throttle the water down to get the desired output temp. When heating water from ~45F to 185F, the throughput drops to around 2.5 gpm. We recover our cooling water from the wort cooler, which comes into my tank at around 140-160F, and the heaters can get nearly 6 gpm for the smaller delta T.

400 ppm TDS? That makes our water look like rainwater!

Zoom: That's exactly what this impeller is. The impeller is a ferrite magnet that triggers a Hall effect counter to measure the flow through the water heater. Once broken, the heater sees 0 gpm, so never turns on, even 'though cold water is now pouring through the heater at nearly 10 gpm. This really screwed up our attempts to make water hot enough for brewing until I figured out what was going on.

I have the replacement parts on hand now, so will soon have all three heaters back up and running. Until next week, when it'll be time to acid-wash them again. That means three days of running on only two heaters, as it takes about 6 hours each to get the lime scale out of them.

Ed: Does anyone do 3-D printing with ferromagnetic materials?

Tell me about it. Our purchase supervisor bought a Regenerative air sweeper even though told him it wouldn't work for our purposes. But the salesman said it would. Now instead of 30 mi aday I can only sweep about 7, 11 on good day. Can't wait when we start doing chip seal in July. I see alot of OT in my future. More money for GPAs

I always thought that was a lawyer or politician... like there's any difference.
