You should be able to rotate the level indicator tube to remove the vast majority of the water. If you want to remove all the water, which really isn't necessary, you can make an access hole on the lid and insert a tube connected to a pump; plug it when not in use. I always treated dwc as an aquarium and only did partial changes every week or so; never had any nute issues.

i have a little bit bigger tubs (60 or 70L) what i have done i drilled a little hole the same size as a little aquarium pump the pump does 200L/h the hose reaches my toilet soo you dont have to carry anything. same with the readings of ph and ppm same hole just a little suction thing hand pump

Siphon hose works in a pinch.. then add pump later

Yeah this is pretty much what I do, I just have a big 100L DWC though, and nothing else, so I have a cheap water pump and 10m of hose, and just drain it out into the toilet in the next room.
Takes about 40 mins to drain or refill, as its quite a slow pump, but it's good for this purpose as it doesn't pump so fast to make me rush around too much!!!
To refil I do the same in reverse, but I prepare the new solution in the bath tub, so I can adjust PH, EC etc. And when I'm happy with it, pump it back in from there.
It's a dedicated pump and hose just for this purpose, so I can pack it up after use, but I do run some chem-san (sanitizer for beer brewing kit) through it before and after use, to keep the hose clean.

I pump outside through a window. If I grew in basement if the drain there goes back to the city idk what id do.
Whatever it took though. If Im not mistaken fertilizer going back to the city cant remove it. Bonds are too strong.

Similar process.
I have a "35 gallon" res that holds 28 gallons of nutes. My pump is 330 gph so it empties the res in 5± minutes. I make a new back of nuts in a 32 gallon trash can, pumping the water into it from a 55 gallon cistern filled with RO. Once the nutes are mixed, I pump the res out into the backyard, move the hoses around, and fill the res from the nutes in the trash can. I adjust pH in the res and then turn on the pH controller.
The whole process takes a bit over an hour.
Fortunately, I only do a few res swaps over the course of a grow.
I saw this scrolling and it's been my age old question as well. I like to bucket swap minei once every other week ( at least )
When mine are feeding heavily sometimes the shits empty but I just swap for a clean bucket of new solution. Been doing dwc for like 10 years and I think this is one of those one or the other type deals. In my opinion it would be more important to swap for clean buckets and wash roots rather than have the scrog. Keep em fed

RDWC is the best solution.

I have seen the light and am converting dwc to Rdwc with the 27 gallon black and yellow tote from HD. 1 inch jaccuzi spa for only 2 buckets.

I have similar. I plastidipped the yellow tops black, then top coated it white. Helps keep light out, while also reflecting it.
Also, the bigger the return pipes the better to avoid roots clogging the pipes. 2-1/2 sch 80 is good, 3" sch 80 better.

At the recommendation of a master grower I am making a dam around the exit of all 3 containers that will stop wandering roots from finding the hole in the bucket. It will not stop a verticle decent by the roots but once they hit the floor they will not climb until the root mass is 3 inches tall. At that point it should be to big to get into the 1 inch hole.
If I was doing a 4 bucket I would go bigger and the future plans are to do so.
I actually went to a hydro shop and checked out the larger tubes. Due to my tent footprint the 90degree bend arc is 1/2 my tent. Unless I exit the tent in 2 places with a 3 inch water tube out on the basement floor it was a no go.

I use cheesecloth in my buckets to "catch" the roots and it prevents any roots from clogging any holes. I use the ones with elastic for 5 gallon buckets of paint. Makes changes easier and quicker.

do you leave them on all the time or just slip them on for res change ?
