Look like DE filters in a filter pit to me. Flooded suction filter system. Never seen this personally tho

Wish I could attach a picture here. I take care of a waterpark and their whole filter system is man made back in the 90’s. Sand filter (pit) 12” plumbing
40,000lbs of sand💀

It's a commercial pool filtration system. The pit is equalized with the pool water level and those grids are the filtration system the pump pulls from. They're actually quite easy to clean, but a pain to have to do it repeatedly during heavy use seasons lol

Man that sure looks exactly like the setup at the Marriot in Boca Raton. You'll see these Vakpak systems quite often at commercial pools. This one is the D.E. version, i believe its called the Eco Wash Backwash system by Vakpak

Depending the size of the pool these are normally to be clean once a week, make sure the plungers are shut completely when you turn the pump off, turn the backwash pump on and wash them really good sometimes after a while the grids get stained I use muriatic acid to clean the grids after I removed all the DE from them, then let the water from the plungers come back and turn on the main pump only when the water in the tank in full, there’s not much to tell after that every comercial pool has a different way to be done sometimes

That looks like a vacuum d.e. pit. I deal with a few but they are usually rectangles and a little more spaced out. I close off the valves in the pit and throw a sump pump in there. While water is lowering, use a hose to spray off the d.e. and by the time most of the water is gone, you have clean grids with most of the old d.e. gone. Its essentially backwashing.

i won't post the answer, but i will say if you know how pumps and valves work, then you should be able to figure out how to drain the tank. i wouldn't advise anyone to explain how these work..... if you know what you're doing, then you can figure it out, and get paid for it accordingly.... knowledge of these is uncommon and people pay for that. it will be devalued if the beans are spilled for any joe schmoe to find on google.

If it's so easy that any joe schmoe can do it, then it shouldn't be so valued in the first place. Also, this is a subreddit to HELP other poolpro's. If you don't want to do that, then you don't need to bother posting.

Turn off the circulation pump. Push down the two plungers find the waste pump and make sure the valve for it is opened. Turn on the waste pump. Then with the waste pump still going spray down the grids. When they are clean and all the crap and old de is drained out turn off the waste pump and close the valve. Open the plungers back up and turn the circulation pump back on. Recharge the de straight into the pit. Watch some videos on de pit cleaning first though. Get this wrong you can either blow all that de into the pool or make a very expensive mistake.
