So, sometimes you have those days where you realize you're an idiot. You know? Today I had a little 'moment' of that. I realized that there was a good chance that the vibration I was hearing came from the tools I had on my stainless countertop that is keen on vibrating sympathetically with the things on it, namely the Robur and, in this case, the Elektra. I took all that stuff off of the table, and went through the test again:
Run motor + pump... Irritatingly noisy. I pulled the pump, and ran the motor. With the tools off, it's super quiet. Impressively quiet. I guess the grease I stuck around the bearings last night helped out. That's good news. Meanwhile, I tried turning the pump shaft. It has a very uneven motion to it. Sometimes it gives a lot of resistance, other times very little. It feels like it has some really bad-off bearings. Rats! I was wrong! I suspect it can be repaired, but it looks like you'd need some special tools to pull it apart. I don't want to mess with it, particularly since the seller has agreed to refund me the money I need to buy a new pump.
I did reinstall the pump and try some heavier-duty descaling, sucking the solution from the bottle. I ran it every 5-10 minutes for about an hour before I gave up and flushed it out... No change. What a disappointment!
I know that the motor could just be quiet because it's not under load, but I guess I'll cross that bridge when I come to it. It's encouraging to know that motors are typically reparable. If I need to, I'll look somebody up. You would expect such a service to be available in the 4th largest city in the country, huh?
As for the carbon filter, I am not sure what its deal is. It significantly cuts the water flow out of the tap (it feeds a sink tap via a T in the line before the pressure regulator, for drinking water) vs. what I get with just the water softener alone. I just bought this new filter about a month ago, and the water flow has been disappointing ever since. It's a non-issue with my Vetrano, but with the Elektra, it makes an awful sucking noise at the filter, not to mention the pump cavitation. The flow rate on this pump is really insane!
I'll post more tomorrow. I'm hoping to make a template for the boiler insulation while the boiler is all disconnected and easy to get at, then patch a few spots on the black frame with rustoleum to prevent rust, reinstall the plumbing and boiler, and test the machine out. The pump will be noisy, but it ought to work.... I hope.
Thanks for all the help, Dave.
