Re: N/A
Sounds like that contractor does not understand steam. The piping has issues but I don't think that is youe problem. This is a one pipe steam system so pipe pitch is important, check all your pipes in the basement and see if they consistently pitch back to the boiler.
Does the water line in the sight glass jump around when it's making steam. If so there is oil in the water and the boiler has to be skimmed - drain and refilling it will not help, it needs a nice slow hot skim to float any oill out of the boiler. If that seems to work but the boiler starts to bang again after a couple of days it needs to be skimmed again.

Re: Rinnai Cycling on and off
I think Hilltown is on the right path. I would guess issue with either the flow sensor or the bypass valve.
Flow sensor can also be checked by monitoring flow rate in the performance data menu.

Re: Rinnai Cycling on and off
even know it has been flushed for 3 hours, is it possible that it is overheating? Still yet, go 8th performance data and watch #11. That is the hex temp.. then compare to #2 which is the outlet temp. Should be about 20 degrees difference. If #2 isnt getting to the set temp but overheating on #11 then replace the bypass valve. You can learn to get into performance data by the tech sheet in the pouch on the backside of the cover

Re: Weil McLain Cga Gold flame error SOLVED
I'd leave the tangled mess alone for now, (maybe not in your case) moving things can temporarily mask intermittent issues. Also IMO you are much better off doing AC voltage measurements than resistance measurements in this case, you will be seeing how the system dynamically works with the normal system loads. With voltage measurements you don't have to disconnect anything. With resistance measurements you have to shut the power off and/or disconnect the device under test. Also with resistance measurements the current provided by the meter is much lower and DC which in some cases may give you misleading information.
Voltage measurements may be easier to understand logically. Power sources (a transformer) should have a constant nominal system voltage. Loads should have nominal system voltage when turned on and zero voltage when turned off. Switches should have near zero voltage across them when closed (on) and nominal system voltage across them when open (or off).
A closed switch (like a Zone Valve End Switch) that has 5 volts across or an erratic voltage, for example, it is bad.
Inspect for loose wires and poorly crimped wire connectors, if any.

Powerpiles
We usually get many questions on power piles and what should the millivolt readings be etc.
I can never remember what the millivolt readings are supposed to be. Used to work on a few now and then but not enough to remember. Always had to look it up. Can't remember where I found this. Maybe it could be posted on this site for others to use @Erin Holohan Haskell
Re: Rinnai Cycling on and off
Do you have a mixing valve after the unit? I've had a similar issue where a bad valve would cause the tankless to cycle.

Re: EK System 2000 hot water tank
Hi, It's clear that the temperature and pressure relief has been leaking also. Put a little bucket under it to catch any drips and see if that lets the floor dry. If it doesn't change things, the tank, or fittings on the tank are seeping as well.
Yours, Larry
