[@WarrenGarabrandt]

Anything capable of moving a large enough amount of water that it makes waves involves an ENORMOUS amount of energy transfer. Any time you have flowing water, or waves moving through water, there is a frightening amount of energy moving that can sweep you away, pull you under, or trap you in a circular flow, all of which can result in drowning. Pools are designed to be as safe as possible, of course, but the parts of our brains that have been molded by evolution to recognize danger are acutely aware of the hidden dangers that water can pose.

Thank you for your explanation on how the drains work! I’ve always been scared of pool drains since I was a child because I thought they’d suck me in. I feel less scared now!

[@sgspec2]

Gravity feed doesn't suck you in. Instead the entire weight of all the pool water pushes you in.

[@thepoolguy]

Just to clarify my comments, not all pools in the US are gravity feed systems. Many are still direct suction. However, all pools in the US are required to meet VGBA standards, which include drains and sumps.

[@thepoolguy]

Hey there, you may be interested in reading this article that describes testing conducted on gravity drain systems, and where the chances for entrapment were very unlikely. aquamagazine.com/builder/blog-the-gravity-drain-advantage.html

[@KenKen-ui4ny]

You think about it, the pool drains and pump system, is almost the same circulation principle as the forced air heating and cooling system in a home, expect it's handling water, air moves through cold air return registers, much like how water is moving through the drain grates and sumps, and they all connect to a plenum, which relate to the surge pit before getting pulled into the filter and furnace, relating to the pumps, filtration and chlorinating equipment, then it distributed back into the rooms through supply registers, relating to the jets in the pools bottom and sides, the reason VGBA standards was due to entrapment, but also entrapment involved in a child sitting on the grate, usually those small round hotel pool type grates, causing a vacuum lock that resulted in disembowelment and death, that why now those small round grates are now dome or concave shaped, so if a child happens to sit on one, a vacuum lock is less likely to occur.

[@jrh5544]

@@thepoolguy “The force produced at the drain by a pool pump is staggering, as high as 1,800 pounds of hold-down force. Depending upon body position, this can even result in evisceration (disembowelment).” I looked it up thinking it won’t be that bad, I am now scarred from this😂

Same here, and wow, Alec was grate for suggesting it; i'm enjoying this channel so much

[@justsomeone89]

As a child i was always scared to get sucked into those chambers. Back then, many pools did not have any protection in front of the large holes. (Some pools were very deep so you couldn't really reach them anyways) It looks like there is a lot of empty space above the waterline in those chambers so if you got sucked in, you would be able to breath. Nice to know that there was at least a way to survive such an incident. Wonder what they would do if it would really happen to get someone out of it. But I still will not swim near them. With the protection it is probably even more dangerous because you can be sucked against it for a few moments. But, Thanks for the information👍 I really learned something today.

[@thepoolguy]

Yes, in theory you could easily survive inside one of these.

[@mrunixman1579]

Going by the Duty Manager of my old Leisure centre who actually swum inside the wave machine chambers as a dare. Providing the machine is not operating, you are able to survive inside them. If the machine starts you will probley be a subject to pressure related conditions or be thrown about with the force of the water. If you was in front of an operating wave machine you can get away when waves are being formed, as this pool is using a mesh instead of bars, there is no way of getting your body parts pulled in to the chambers by returning water. Loads of kids used to enter the wave machine chambers at Letchworth by removing a bar or 2.

[@ryanmalin]

surge pit is a great idea. I cant tell you how many leaking main drains or skimmers i delt with doing residential pool service when I was younger. I would sell everyone new jandy valves, new shaft seal, new leaf basket oring for the pumps. If that pump leaf basket wasnt 100% filled with clear H20, I would not stop looking for the culprit. My StaRite DuraGlas pump lasted 13 years on the oem motor and another 8 with a new AO smith and PS100 shaft seal + copper heat sync. I loved that pump that thing was a beast. Sold a ton of Great White cleaners to my customers as well because they held up to tons of neglect.

[@thepoolguy]

I would say that I have fallen in love with surge pit pools. They do have their own issues however.

[@OmizaruHaven]

I did Solar Installation in the Caribbean for a while. For those grates try hammer-drilling out some 1/2" holes (at least 3" deep) and use some Simpson Strong Tie to epoxy 3/8" stainless all-thread into those holes. Drill corresponding holes in some fresh grates. Keeps solar panels down in 165mph hurricane force winds!!

That room fills up with water that becomes the next wave and in this case, submerged Penn in it. “The room would fill up with water to the top and I would hold my breath and then it would push the water out to make the wave and it was really rough inside there,”

This was great. Thanks so much for the information. I bet it sounds and feels crazy in that air chamber when the pool is running. With all the opening and closing of valves and the mass amount of air moving between those chambers it would be a neat experience. Do those fans that control the air pressure in the wave chambers run continuously and the output is controlled with valves? It looks like a centrifugal pump, is there any issue with stalling the pump? I dont know much about the fluid dynamics in that type of equipment and centrifugal pumps are not positive displacement so i guess it would be ok. This video just makes me want to learn more about specifics in the principles of operation.

[@thepoolguy]

These are setup similar to a squirrel cage blower. The wave system soft starts the motors on a timer. Approximately every 15 minutes the waves run for 10 minutes. The forces inside the wave pool are fun. Windy but very loud. 120db. Double hearing protection required.

@@coondogtheman ahh, I see. Unfortunately no. These are made of a Glass fiber reinforced abs plastic I believe. For sure not plastic.

[@TheUnknownExplorer666]

Question if u go near the wave thing where the metal fence is under water can u get stuck to the grate due to the water pressure going back in the chamber

[@thepoolguy]

Ive been near them, the forces are not too terrible, but you really dont want to be on them. I was using scuba gear at the time so I had no issue with breathing.

[@marsrover001]

Here I sit at 1am watching a guy talk about pools. Thanks youtube recommended.

[@thepoolguy]

Welcome sir.

[@brandoniron4011]

Thanks for showing this kind of stuff. A few things you might consider. One is just because it’s not “direct suction” Does not mean it safer or will not cause an entrapment. They definitely move water into the pipe. Hence the reason water flows from the pool into surge pit. It’s called Delta P. And is a very dangerous situation. Depending on the difference between the two water levels, it will increase or decrease the amount of vacuum that’s created. The plumbing being hydraulically split helps keep it from happening. But it’s still dangerous and I would never trust that. If a few pipes got plugged up it would render that safety feature useless. Please be safe if you ever work on your drains while Pool has water in it. Looks like someone has Been using carbon steel anchors to bolt the grates to the wall. Should be using 316 grade stainless steel. Also need to use antiseze on the threads. So you can remove in the future. Also them grates should all be bonded to the shell reinforcement and any other metal parts of that pool. Lights, handrails, pumps. Bonding any metal in the water is a must. Should probably put a Acorn nuts over the tops of the threads sticking out to. Again not hating on you. Just trying to help out. Been in the industry for 20 years. Have plumbed Olympic size pools using up to 12” schedule 80 plumbing down to hundreds of residential pool. So I’ve been around it like yourself. Just never took the time to shear it like you have. So thanks man.

[@thepoolguy]

Thank you for your suggestions.

“One is just because it’s not “direct suction” Does not mean it safer” @ Brandon Iron. Umm hello..yes it is DEFINITELY SAFER than direct suction lol. Smh

[@ultimatedude5610]

Those drains always were a nighmare for me, it was just they were huge and whenever i swam I started panicking if I was overtop of them. One time I actually got stuck to the side of one of these they were on the wall and near the top where you exit.

[@hammerdick82]

Just a thought, but would a channel at the base work better to hold those grates instead of bolts? Then all that needs fasteners is top and sides. That way its mechanically held against the pressure on at least one long side

[@thepoolguy]

Hey Chris, we haven't actually thought of this. I'm gonna see what I could do to try this on the one we currently need to work on.

[@hammerdick82]

@@thepoolguy I worked on a oil rig for 10 yrs and with high flow stops it always has more longevity if the screen has recess to lock into as opposed to fasteners. I imagine a concrete saw for a groove and lay in a c-shaped iron piece, it would also help alleviate pressure on all the other connection points as well, if the groove was deep enough. Though youd have to make new grates that were taller. I always enjoy efficiency improvements. Best of luck to you buddy

[@RGRrgracingfrrgr]

Great video!! do you know how many presure are in the chamber to push the water ?

[@thepoolguy]

That I do not know

[@SweetestYaya]

I have an intense fear of all drains and I made it 1:13 before I stopped, I just can’t when right behind me when I’m watching this at work is a pump room for all the fountains and pools in our hotel. I’m dying. I’m going to try and watch this when I get home. These seem interesting and I should face my fears 😩 It doesn’t help some pipe keeps bursting and drain keeps failing and we keep getting water flooding through the bottom of the wall into our side. Just on the other side of the wall.. I can’t 😭

[@OC3AN1X]

I made it to 1:02 before I nope-d out 🙅🏻🏊🌊

[@beachbum4691]

I watched another video on wave machines and got the impression it worked by sucking the air out and producing a higher level of water within the Cassion, it seems I was wrong? And is air pressure pushing down creating an artificially low water surface within the Cassion which displaces water into the pool creating a wave? perhaps there are several ways of achieving a wave? great video thank you for taking the trouble to produce it and post it :)

[@thepoolguy]

Your assessment is correct. And there are a few ways waves are made

[@ChrisLuvsRoses]

So if your near the grates when the valve opens and those fill back up with water do you get trapped until it fills fully?

[@thepoolguy]

That's not something I have ever tried, nor would I.

[@arongambino2500]

Sick

[@racookster]

I heard about a maintenance worker at the now-defunct Water Mania park in Kissimmee, Florida getting sucked into a wave pool turbine and decapitated, but it turns out that it wasn't a water turbine. It was one of those big air blowers. Apparently, he got his head too close to an air intake (shown in this video). I guess it's about like getting too close to the intake of a jet engine. So much for being afraid of the underwater sucky-parts! It was just air suction that got him.

[@neongirl]

If I understand correctly, this worker was at his post in the engine room and for some reason decided it would be fun to stick his head into a running centrifugal fan? Well, idiocy can be life-threatening.
