What Am I Working On? An abbreviated photo dump of the month's activities.

JohnNY · May 23

Troubleshooting and writing proposals is how I spend most of my time. The toughest part of it is switching gears several times per day between the multiple systems, locations, and clients.

The first picture is a municipal steam-to-water heat exchanger that provides hydronic heating to a church and food pantry in midtown Manhattan. They're overheating.
The second is of a Leonard mixing valve in Brooklyn. Water temperatures are inconsistent.

Third is an Aerco Benchmark getting too hot too quickly.

Fourth is an NTI high efficiency system installed by the irretrievably clueless.

Fifth is a duplex ejector system in a single family residence that needs constant attention because it fills with cooking grease twice a year.

6th is a high efficiency boiler installed with a back-pitched flue resulting in daily lockouts.

Last pic is graduation day for my Plumbing and HVAC students at The General Society of Mechanics and Tradesmen of New York City's trade education program called Mechanics Institute. This is a big day for me at the end of every 2-year program.

Questions and comments are most welcome.

#1 The steam to water HX. It can't help but overheat where the sensor is located its not in the hot water.

I used to have to "switch gears" all the time. I think that is what caused my anxiety.

Last is a high efficiency boiler installed with a back-pitched flue resulting in daily lockouts.

I wonder if you might need a few more pumps on that one…………………….😉

You look like the proud dad after the kids graduation from middle school. Great work John both with your students and all your jobsite work. Thanks so much for sharing.
