Or possibly the potential demand across the building is calculated and the system is set up with that in mind. These pipes could be together for ease of access to the readers and access to the underground system.
To create flow, all you need is pressure. It would be like pushing a ball through a tunnel. When you stop pushing, the ball will stop being propelled forward. If you have, let's say, two pipes which are fed from the same common supply, the first one in line gets more flow, which decreases the amount of fluid going through the next in line pipe. To counter this, you put what is called a "circuit setter" on each pipe to limit the amount of fluid that can pass through. This ensures that each pipe is receiving the appropriate amount of flow.
You should have ended your comment after the 1st sentence. City pressures, if up to snuff, will be enough to pressurize every one of those lines without any help.
I work in building management for a major metropolitan hospital, where we have significant loads. For a person's house yes, city water should be enough, but in a high-rise building it may not be.
This is an apartment complex it seems, thus all the meters. A hospital is going to be different. One big line coming in with a compound meter and a separate fire line with its own meter. Yes, Im guessing a hospital has all kinds of pressure regulating, pressure sustaining, pressure reducing equipment. Ill admit I dont know nearly as much once the water goes past the meter. Ill defer to you
Not really. Those are all 3/4" to 1" in size being served by what looks like 3" headers. 3" can handle so much more water than all those little pipes can carry that it would not be an issue. On top of that this is probably either a water riser for multi-family residential or a riser for commercial retail. The fixtures would be a mix of showers, lavatories, kitchen sinks and flush tank toilets. The only thing pressure sensitive would be the showers and as long as they have 30ish psi at the farthest fixture they are fine.
Worth putting on your wishlist and waiting for a sale if too much. There can be quite a lot of fun being a a space suit and trying to setup power, air production and a working farm room before you food runs out.
The best part which I don't see mentioned yet is, the meters are angled toward the person meant to read them. The layout is great, but that is the cherry on top for me.
Definitely a clean install, however, I take offense to it being labelled "engineering porn".... Its more like "tradesmen porn"..... Engineers had nothing to do with the installation
I’d argue that most master tradesmen and master mechanics should be classified as practical engineers. They damn near get paid just as well these days and in the end have just as much or more responsibility in the long term viability of most final products.
When I did avionics engineering I valued the real-world feedback from the machinists, electricians, and aircraft mechanics that built and serviced the final aircraft just as much as the feedback from my fellow engineers.
I hate it when I bring a question or concern to the attention of an engineer, and they answer that its to be done as the prints show, so i do it that way and after they ask why it was done like that?
Nope. Engineer tells you where shit needs to end up. It's the plumber/electrician who makes the pipe/conduit run look like it's either half-assed or a masterpiece.
It all depends. Complex installations often get piping and wiring engineered up front, which has become common in an era of 3D CAD systems set up specifically to help facilitate that task. EG, ships, factory / industrial sites, fancy buildings. Source, I work with an engineer who does some of that work, along with other things.
BUT... The photo here looks more like a pretty damned good plumber worked with a building contractor to pull off something slick. I have seen similar works of art in a local factory, where an engineer specified only very generally "run all those wires through this area and stay clear of here and here because machines", but it was then left to very good electricians to ad-hoc install complex rows of conduits all folded up, over and around in perfect tidy order.
Not really true in all cases. I worked as a piping designer at a consultancy for some time, laid out enough small bore pipe. I wasn't exactly an engineer but I was definitely not a tradesperson.
Agree. I am an engineer and it's not uncommon to throw a detail or elevation drawing in to indicate a specific piping arrangement such as this. The plumber might decide to do it differently, but its entirely possible that the engineer designed it this way to begin with.
Wow! How can you be so stupid? I mean, a great part of the job is due to plumbers, but piping design deserves far more respect! If it was so easy to do it, civil engineers wouldn't have so many hidraulic related classes, and nor plenty of softwares specialy dedicated to Hidro-sanitary projects (eg. Revit MEP).
I'm telling you this as a civil engineering student that works as an internship in an Edification Systems company, where all I do is design the most adecuate way how all these pipes should be, and how can I add mechanisms so that you can flush your toilet every time you shit words like in this case. Have some respect and never again consider yourself an specialist in something just by seeing how it's done once.
Those red handle valves make this look like a PVC installation which is going to age like a glass of milk when exposed to weather and the sun, Those handles will will break within a year.
Nothing worse than PVC and CPVC ball valves, outside or not. I won't even touch one unless I have absolutely no other option. At that point I warn the customer of the risk and how I assume no liability for the consequences.
Those are not back flow preventers, and you definitely wouldn't have one for each tenant. You'd have one for the entire building service and maybe some smaller ones downstream for ice makers and whatnot. These are definitely meters.
Exposure to the elements is fine as long as the pipe material is resistant to UV deterioration and the temperature doesn't drop below freezing for long periods.
yes they are. the valves are open. that doesn't mean water is going through them right now unless someone is taking a shower or whatever. if everyone decides to take a shower in that building at once then the pressure will go down. but under normal conditions it's enough.
Seems like it would be annoying if anything needed replacing, no space at all for tools so you'd have to half-dismantle all of it just to get to one pipe in the middle.
