Re: Best Material to Use for Drainpipes in Residential Homes.
if you're putting string down the drain it is likely to get tangled on something regardless of material.

Re: Best Material to Use for Drainpipes in Residential Homes.
No-Hub cast iron has always been the top shelf material here and of course, the plumber installing it has to be of equal quailty as well.
No-Hub cast iron drains, ABS vents. For commercial work or houses over two stories, the materials had to be all metal, so we used DWV copper for the vents.
In the beginning, we used a chain snapper to cut the cast iron, but then transitioned to a chop saw as it was faster and the cuts more accurate.
Re: Boiler
The best one is the one that’s installed and maintained properly by a competent hydronic pro: he’s 95% of the equation.
Find the best hydronic contractor and go with his recommendation.
However, the Buderus is the best cast iron oil boiler.

Re: Is the circulator pump too powerful?
I suspect that a Flo Control (check) valve would solve this. I Imagine Zones 3 and 4 are next to each other?
Really, each zone should have it's own flow control valve.
Re: Correct system, plumbing errors
With those tees in the main with plugs I wonder if the counterflow drips were removed?
Re: Heat will Not Turn Off
I did another heat run - heat comes on with thermostat call, and shuts off when temp is reached. Heat LED goes goes off for the zone on the HZ311 and purge LED comes, and stays on for 2 minutes, until relay clicks, LED goes off. Blower stays running for 4 additional minutes then goes off. I think this is normal.

Re: Heat will Not Turn Off
One step at a time. Heat continues with thermostats "off"? OK. Remove thermostats from wall and disconnect. Heat stops? Bad thermostat. Heat continues? Go to other end of thermostat wires at control, and disconnect BOTH wires (or all three (note where they go). Heat stops? Bad wires. Heat continues? Now you can start investigating the control.
Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
Might be the socket for the CAD cell too- I've seen them go bad.

Guys were using the Cell-Core Foam Core for Mod Con exhausts and they were degrading quickly. That seemed to be the time, they outlawed regular PVC as well. Mad Dog
Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
In the first picture it looks like a burn mark on the cad cell wire. Maybe it got pinched between the transformer and the electrode.
Your technician is an idiot.
How does replacing electrodes improve a cad cell reading? It doesn't. Nozzle ….maybe.
Could be the burner end cone is damaged although if he got a good combustion test probably not.
How do you spend 2 hours on a burner knowing the cad cell reading is high and not get anywhere?
