Re: I built the wall...............after I knocked it down
So your 2" header doesn't even meet the minimum spec from WM. Using both risers doesn't allow you to downsize the header.

Re: Delta T pump, circ controlled zones, with a Prestige Excellence
could it be in the lag time of the sensors? Different types of thermistors respond differently. Here is a link to some good reading on sensor types and how they can be engineered to specific needs.It looks to me like those time constants are mostly about internal heating from current flow.

How the thermistor is potted will make a difference, but I'm pretty sure a thermowell would solve most of the issues with inputs for the pump controller. Unfortunately, adding thermowells to an already crowded near-boiler pipe job is not always practical.
I'd still like some kind of configurable loop gain (even a low-medium-high would probably do it) to accommodate different system characteristics. An external speed input would still be best.

Re: Dayton 3UH62 furnace house blower not working.
Could you post more pictures:
Remove all the fan motor wires from the board so all the writing may be seen. Picture of that please, I am not familiar with that board so I need help.
Also a picture of the wiring diagram that shows the board connections.
Thanks

Re: Trouble filling hydronic system to second floor
1/2 PSI per foot of vertical system elevation above boiler, plus 5 PSI. Bottom fill, top vent (which you are doing). Adjust the pressure reducing valve to meet your elevation needs, typically 12 PSI for residential. May have a plugged strainer on the Pressure reducing valve.
Take pictures.

Re: Sch. 40 pipe pitting off the equalizer after 4 months
Thanks @Fred. I'm going to check water quality. New fill this fall is as explained.
Curious thing is it is ONLY that one 3" nipple, at the dead end as the equalizer goes down to a tee, one side goes back into the boiler, and the other into that dead end 3" and a cap - pic 4 in 1st post. Cap is fine. That's why I'm wondering if it has to do with a combo of large weld ridge inside the length of the nipple and the swirling or vortex of flow from the feeder motor and equalizer. You know how copper line can pitt inside a water line if saulder runs through and into the pipe creating an obstruction inside the flow, and running water creates a small vortex around it that eats the tube from inside.

Re: Does a boiler pressure relief valve need replacement after a single leak?
What @JUGHNE said is 100% correct
Re: Recommendations on wall hung lp water heater for radiant.
I am afraid these boilers are just out of my pricerange.
I might have to just set a 40 gallon water heater in the corner and do it that way
I thank you all for your input and time spent.

Re: I couldn't find this one in the search box.
It was a high end system in it's day. Modulating control, possibly with centrally controlled night set back. There's plenty of this still in service, parts shouldn't be too hard to source (although $$$). You should be able to rehab it cheaper than "updating" it to modern controls, which will entail replacing the actuators or using solenoid valves to give on/off control.
