IMPORTANT NOTE: At 5:30 when Alex says they are using “Red PEX” instead of “White PEX” what he meant to say is they are using “Oxygen Barrier/Closed Loop/Radiant Heating” PEX or “PEX-AL-PEX” instead of regular PEX. The color of PEX DOES NOT indicate it’s official capabilities, but is just meant to helpfully color code to keep track of things like which line is hot or cold. So regular PEX can come in white, red or any variety of colors, but that doesn’t mean it has an “Oxygen Barrier/Closed Loop/Radiant Heating” PEX. “Oxygen Barrier/Closed Loop/Radiant Heating” PEX and “PEX-AL-PEX”, while typically found in red, can also come in other colors.

But the manifold looks jank and I don't think he has any sensors checking loop temperatures, pressures and flow rate. Also he would need to slow the pool pump down once it gets cold outside, to avoid condensation inside. Check the temperature of the heat exchanger and set a minimum temperature for it and shut the pool pump down once it is reached. It's very well possible he has done this, but its not covered in the video.

I like source - device in - device out - return. Arrows are very important because some pipes can see reverse flow in some conditions so specifically calling that out is an important marker.

[@mirror71]

HOT and COLD are the correct labels as there is no way to confuse those. Since he's using QDCs on the computers, those should also be gender-matched so that the COLD port on the computer is female and the HOT port is male. Even without labels, gender-matching QDCs in this manner is the correct way to do it. The flow direction should be from male to female. Thus, the COLD supply side of the manifold should have male connectors, and the HOT return side of the manifold should have female. Apologies for the reply to an 8-month-old comment.

With your reservoirs, you should have placed the bulkheads at the top with internal tubes that reach the bottom of the tank. This leaves you without needing to worry about leaking. Plumbing 101. Something else I would do with the distribution blocks is place them outside of the server rack and below your servers (or at least just below if you do keep them in the rack) that way if they do begin to leak in the future you have much less, if zero chance of the water flowing down the tubes directly into the backs of your servers.

With the dist blocks below the servers you'd need to worry about air bubbles resting near the quick connects. But I do agree outside the rack would have been smarter.

[@greggv8]

Should have used PEX-A instead of PEX-B. The expansion connections for PEX-A have almost no flow restriction because the fitting inside diameter is the same as the tubing. An expansion tool is used to stretch the tube and a compression ring. Since it takes a few seconds to return to original size, it's easy to pop the fitting in or slip the tube on then wait a bit. Next to impossible to get it wrong. The tube and ring is constantly trying to return to its original size so it's always exerting pressure on the fittings. If an angled fitting isn't pointing the right way, it can be carefully twisted around inside the tube without causing a leak. PEX-B fittings have an inside diameter that's smaller than the tubing. The metal crimp rings can be crimped poorly in many ways. The tubing is always trying to return to its original size so it's *pushing outwards* against the crimp ring, the same way water pressure is pushing on the tubing. All that's keeping it in place is the metal ring. If the fittings will be exposed to conditions where metal can corrode you must use stainless steel crimp rings. Otherwise the rings can corrode though then there will be leaks. If PEX-A gets kinked, simply heat it up with a heat gun and manipulate the kinked area to help it restore to shape. If PEX-B gets kinked the kink has to be cut out. Installing a coupler* to fix it adds another flow restriction so it's best to pull the whole length of tube and replace it (use the pieces for shorter runs) or cut it off and pull more from the roll, being careful to not kink it again. *Or decide that the kinked spot is where you were planning all along to install a T. For redoing connections on PEX-A you use a sharp utility knife and a heat gun. Carefully slice across the ring and heat. Slice deeper until the ring splits - without cutting into the tube. Heat up the tube and it can be pulled off the fitting. It is not recommended to re-crimp PEX-B. A bit of the tube should be cut off after cutting off the crimp ring. With either type, if the tube gets cut or nicked when taking it off a fitting, cut the end off to get a fresh end. If the sealing surface of the fitting gets scratched (especially across one of the ridges) it's safest to discard the fitting because it could leak.

Around 11:49 they talk about labelling the flow-direction. This comment is soley based on my experience as a Marine-/Operations & Maintenance-engineer, in Denmark, working with district heating, sea water heatpumps and what not, within those categories. Practices vary based on location. The flow direction is best labelled (example ANSI A13.1) with arrows, description and color coding (hot, cold, in, out etc.). Even on smaller projects like this it makes a huge difference doing the proper groundwork before commissioning, if it ever goes south (probably will, them manifolds sketchy). AND for the love of god, get those manifolds out of the cabinet and put a drip tray under them! Also saw another comment suggesting putting leak-detection on the system, also a very good idea.

It’s hard to tell what happened because after he yanks the cord out like a child would, it cuts to all the new cables connected so who knows. The amount of smoke makes me think the cable worked for a short time and something got super hot. If wires were crossed it would have tripped the breaker instantly with no time to heat up.

[@TheEmpowerment1]

In reference to the switch blowing up and what most likely happened. You need to have your rack directly grounded with a strap and grounding rod (best practice is 2 rods 16ft deep). Rack power strips and equipment have high leakage current and in turn high ground potential and basically stray power can then discharge to the nearest most receptive equipment causing exactly what happened to your switch. So when you unplug something in the rack any residual power in capacitance gets discharged thru ground and because you yanked from your c13 end and the grounding pin is barely longer than the power pins it allowed the current to discharge into an already charged grounding system it was enough to blow up a power sensitive piece of equipment. Also you should bond the rack from top of rack to bottom of rack with a cable large enough for it to be the path of least resistance usually with a big beefy copper braid cable. Also all the rails (Rails meaning your verticals of the rack and not your slides) should be grounded and bonded with a large strap as well because everything is powder coated with only screws bonding grounds to all the pieces of the rack. Also I know you dont want to hear this but your manifolds should be at a minimum be bottom of the rack and optimally externally mounted. Datacenters spec 12 to 18U bottom rack mounting for "leakables".

[@geoffsmith82]

The hoses from the manifolds should have had a drip loop.... as in the hoses should have gone down below where they were connected to the computer and then come back up again. What will happen with the current setup is if there is a leak at the manifolds, the water will trickle down the hoses straight to the outside of the computers. The water will likely then have a good chance of finding a way into the computer cases.

[@WackoX1337]

Also Iodine itself is a relatively reactive element it may straight up attack your cooling blocks/plating's etc. You don't need anti-freeze but there's other types of algicide and corrosion inhibitor type stuff you might really want to look at instead.

Calcification in his pipes pump and block where the water gets hot or even just slightly warm is going to be a HUGE issue within 3-4 months as well because of potassium added, actually to further expand to this, this entire project failed the moment they didn't even realize they borked it up immensely.

And there isn't even a performance reason to forego it, the pool water has plenty capacity to keep the heat exchanger near the same temperature as the pool water itself.

[@zierlyn]

@graealex It was never the actual pool water. There's piping running through the concrete floor of the pool. Like reverse in-floor heating. On an unrelated note, the only thing I recommended last video that they didn't implement is a heat-exchanger bypass through a simple fan coil. As it is, if they have to shut down the pool glycol loop for servicing, the server will have no cooling whatsoever. Secondly, if the glycol circulation pump dies, the server will have no cooling. The bypass valve would be set to automatically switch to the fan coil loop if the pump stops running. Thirdly, if the glycol loop drops close to zero in the winter, there will be condensation issues. The bypass valve could be set to modulate between the HX and the fan coil to maintain a minimum safe temperature for the indoor loop. I was an HVAC Automation Controls technician, so it was my job to program these kinds of setups. Now that it's coming up on winter, I expect to see a part 3 where they deal with condensation issues.

Pro-tip when troubleshooting a short on a DC fuse without needing a ton of fuses or cooking circuit breakers. Put a light bulb (sealed beam headlight works great) in place of the fuse with jumper wires. It will limit the current flowing through the circuit to a max of whatever the bulb will pass (usually 3-5 amps for a car headlight), and if you still have the short, it will light up bright. Once you eliminate the short, it will drop to dim to not at all depending on the resistance left in the circuit.

I hope you are going to put some foam around those pipes outside, pex is not to be used outside in direct sunlight, the UV rays will kill it over time.

If that's true, this is an important comment! Hopefully they see it

I give it three months max. In the summer.

I don't think they know considering they used PVC outside for pressure and PVC along with PEX don't do well with sunlight. It's why PVC should only be used outdoors for drainage and not pressure What they should have done was used copper and then transitioned to PEX when out of the sun. Take that conduit pipe the pex comes through put a box on top of it and in the box make the transition from copper back to the pex. Also if his plumber told him it was ok to use pex outside, get another plumber. Honestly you should just get a plumber that works with wells, there are quite a few things you could add that wouldn't kill your pressure. For example get a uv light system installed as well like they do with well water, it will kill the bacteria in the loop. They make rather larger sediment filters, and pressure tanks that could work with your pump so the pump is not running 24/7 burning itself out all the time.

For the "in vs out" confusion, you should be naming it "chilled water supply" and "chilled water return" for the Server loop, and "cooling water supply" and "cooling water return" for the pool loop. That would remove any confusion about which line you are talking about.

Keep it simple - just Hot / Cold and Inside / Outside

I actually had the same issue with tubing. Core memory, I was playing Half Life Alyx, and my cat was sleeping ontop of my computer, covering one of my exhaust fans. The other fans didn't ramp up, and over temp protection didn't really work, and it just caused the tubing to get hot and melt / deform, causing a massive leak.

For the amount of holes in the manifold, you either need an extremely high headpressure or a much bigger pipe going into the manifold. Another problem with a manifold is that the loop with the least amount of resistant will get the most amount of water. Just some things to keep in mind.

A small pump in/for each system would be much better. But that's not as janky 🙃

@@triplestaff isolate each loop and use Air to cool the radiators and it's a perfect system \s

At the end of the video you talks about turn on/off the computers. You have Home Assistant already, you can use it. You can create virtual sensor to see each computer if it’s on or off. Option 1 (soft option): If the computer’s connected with RJ45, wake-on-lan (magic packet) and better if the computers have static IP. Option 2 (wire connection ): Use Shelly 1 (or similar) use it as dry contact to the wires of the power button and you can set a virtual switch in Home Assistant that will turn on and then off after one second. As well for force off create an automation that will turn it on for 6 seconds then off. Even if Home Assistant is down, you can do it from the Shelly app (but then you might have bigger problems…)

I love the edison motors hat. Glad to see someone else supporting them!

I'm surprised you've not rigged this all up with moisture sensors to avoid this in future
