Weil-McLean Boiler

Since about the 1990s WM has been placing a small yellow label on the left side of the boiler. That label has the date on it.

Otherwise, look at the gas valve, relief valve, circ. pump. fill valve, aquastat, etc. for dates.

The CP lookup often works, but I know that for some reason at least one model they have made in the recent past is not included in the database.

Does someone have a picture of the dates on a gas valve or TPR?

I have yet to find them. I even just went and looked at my boiler and water heater. No dates.

Here are a few examples. The label on the boiler water feed valve looks the same at the PRV. On Conbraco PRVs the year is usually stamped into the round metal label on the top of the valve.
