Sent out today for the Dairy Walk In reported as having a water leak from a pipe. I found that the leak is at the termination of all the coolers shared drain lines. They terminate at a branch of the store's Evac Horizon Jr Vacuum Overhead Drain System.
I found that the riser for the Dairy Walk In cooler is the only branch experiencing water flow issues. Found that the Pinch Valve is failed and causing water to pour from the Activator Ports during defrost cycles high water flow. Also the Vacuum System is losing vacuum pressure and a leak needs to be fixed. Had to depart at 11:00 PM per manager and return in a few hours. I will be returning early in the morning with a second technician to help identify this leak and replace the pinch valve If it can be acquired at our local distributor.

I always seen these/stared at these when I was there shopping. Nice to see the behind the scenes of how they work
Yes, pretty awesome. I need to do a better job delivering the information though I think. takes time to get this content creating to a good place. I'm glad you liked it.
not bad. maybe start out with an overview of the system and describe the problem you are trying solve. It was toward the middle where you showed all the vacuum drops to all the units and explained the system. be careful working at height too@@mastertechnicianmindset2181
Need a scissor lift for any repairs and do it after hours for Costco , don’t miss those calls!!
I work on this system for Costco. Its a learning curve but easy once you do every component. System needs to be kept CLEAN for maximum performance. I am a walking EVAC knowledge base.
This set up is new to me looking forward for part 2
Cool man. I'll get it up for you tomorrow, hopefully. I'm on call till Tuesday, but I'll try for sure.
this is a great video bro, i wouldnt have known where too start. lucky for you, your system has ball valves on the floor
I didn't really know where to start when I first saw these systems. Spent many hours researching And reading to understand how everything works together. Out here they just throw you out there to the wolves. Pretty much and gotta figure it out yourself.. I've ran maybe 4 or 5 calls on it already and I'm starting to get a pretty good handle on it.
I never did any super market refrigeration. This is something new to me but I can see where it makes sense to have in a large number of display cases. Next time I’m grocery shopping I will have to look up and see if they have this type of system.
Yea i dont have too much knowledge About this type of system but it's really cool. I wish I would have invented it. it makes perfect sense. Yeah look up it's gonna be in your big wholesale Sam's competitor
@@mastertechnicianmindset2181 Yes I kind of figured those are the types of places that would use it. I can see where it gives them freedom to remodel and not be limited by floor drains. Basically just a huge condensate pump but more expensive and elaborate.
@@czechmate6916 That's a great way to look at it. Because that's exactly what it is.
it's inches of Mercury, not inches of Hg (Hg is the symbol for Mercury on the Periodic Table)
Yes, you're correct
where do you get that pinch valve? I've only seen them for tiny 1/4"-1/2".
I'm not exactly sure. I'm gonna have my parts guy place the order for the parts I need on Tuesday. And the have to just wait and deal with the water leak until then. That's coming up in Part 2
Why would you NOT have floor drains? Why would you use this crazy system?
im not exactly sure. it could be a different process for builing large scale. instead of DWV piping within the concrete slab, this is a different option. Actually seems easier to maintain since it can all be accessed in the future, as piping buried inside a concrete cannot
Remodel/Adding new cases, easier to have this system instead of all that plumbing work I suppose
That is basically what the manual said. @@hvacr_wa4282
I think you are correct. They would be cutting concrete to move floor drains around every time they rearranged the store.@@hvacr_wa4282
@@hvacr_wa4282this is the right answer. For remodels and moving/adding new cases.
I can understand the reasoning for the overhead drain lines, but, it seems this system is overly complicated.
Why not just allow the waste water drain into a pan and have a pump push the water overhead to the sewer system.
This appears to be the overuse of technology when a simple pump could be used.
Keep it simple.
I believe that the purpose for this design is to have a fully pneumatic system, requiring no electricity through the collection network. If we use pumps-we require power. I think also they promote the smaller diameter piping compared to DWV. Don't get me wrong. I don't sponsor them or anything like that. that's just what I've read on the literature.
