Chilled Water Pump Station

We replaced the chilled water pump station in a 52-unit apartment building in Arlington, VA.

One of the pumps had failed and the piping was rotted out and leaking. It was time to replace this.

Here are the before pictures:

    Poppy and his crew spent close to a week piping in the replacement Taco pump station.

    We finished this up in May and started it up in early June.

    FYI - Poppy is retiring on August 31 and moving back to his home country, Bosnia. He has worked with me for close to 20 years. When I hired him in 1999 he could not speak English and did not know which end of the wrench to grab ahold of.

    He went to night school to learn English and finished first in his apprenticeship class. He is now my right hand man and runs my biggest, most complicated jobs. We will miss him.

    Everyone does thing differently. I would have used a flanged CI reducer on the discharge instead of the PP reducers. Also why the Y strainer? is their not a strainer in the suction diff? Nice looking job, solid and straight.

    Congratulations to Poppy on retirement. I am counting the months myself...less than a year.

    My best wishes to Poppy, I hope he has a well deserved retirement. I think you both learned a great deal while he was on the team.

    Still looks oversized? Why two pumps? Why such a big expansion tank? I know it's none of our business. At least replacement wasn't a variable speed to further muddy the waters.

    Not oversized. One pump is a back up/ Standby. Pumps are rotated for even wear. Flow is adjustable with VFD's.

    Great looking job, Dan! I’m always surprised to see mechanicals rooms in Arlington that I’m not familiar with! Lol

    How much commercial work do you guys do?

    @ Ed. Yes, there are many ways to do a job. I like your idea of the CI flanged reducer.

    @ Hot Rod. Yes, we both gained from the experience.

    @ Mike. Maybe 20% of our work is commercial. Mostly boiler work with some rooftop units and chiller work mixed in.

    This one was on N Meade St. near Rt. 50, directly across the street from the Iwo Jima Memorial.

    @Dan Foley I work at 1310 N Meade right next to that several times a year. Never been in that one though. Great area. I think I’ve worked in about every one of those new buildings across route 50 from there. Great looking work as always.
