oh hope someone can help me come up with a solution quickly for this issue..
I am using rolling benches and drain to waste.
-12 inches off the ground (these are low benches. not much room under)
each bench slides about 8 inches to each side, so location of flood drain/trays are moving..

I want the water to drain/pumped out through a wall at about 10" off the ground..

how can I connect three trays to drain down to the floor and then be pumped out through the wall..

has to be some type of self priming pump..
how can the three, 3/4" drain lines all connect and pump water away.. obv I will want to keep the water contained/no sitting water in room..

thanks to the savage who can solve this one!

I can swoop this up locally today.. 1.6 gal/minute is a lot less than your 1100gal/hr .... but I am using Rockwool so I assume I will have a lot less run off?
and maybe this 1.6gal/min would keep up? is your 1100 overkill?

It’s sufficient to pump up to 30’

My 1100gph

I had a condensate pump for my set up. It was ok with 4x 5gal hempys. It lasted 5 ish grows and packed it in.

I figured how to get mine to gravity drain into a floor drain and went with that. Simple is better IMO

Another option (which I use) is a ShopVac Pump Series. I have 3, 20 ft sliding trays, and they have a 2 inch drop from one end to the other. When Im done feeding, I just set the vac hose at the end of each tray to suck up and drain it into my sink. The ShopVac pumps out the water through a standard 5/8th garden hose fitting. I drilled a hole in the side of my sink for the waste water connection, and a 90 degree PVC elbow to keep it from splashing everywhere. I never have to take the lid off of the Vac because it pumps out as it sucks up water. There is only about an inch of water in the tank at all times. I do clean it out every grow tho. It does pump like crazy!.. pump is rated to pump vertical 50 ft! To the OP,.. I had thought about connecting the 3 trays at one point, but the hoses would be in my way, as we use mechanics stools to scoot around checking and feeding plants.

Also!... I've overfilled that tank more times than I can remember, and it's handy for cleaning up my mess. I think it was like $125 on Amazon.

I did buy that condensate pump I linked above. I am super happy with it. I clogged it up once the first day with some plastic shavings but it has been running good for over week now. It has 4 holes for I can hook up all my trays and my dehumidifier.

Bilge pump with a float valve built in. Once the water level reaches 2” it’ll activate the pump to pump it to desired location.

I use a 1100gph one to pump my waste to the opposite side of my basement directly into my floor drain.

Exactly my method as well

Hello, if the collection tray(s) are plastic, drill a hole at a low spot that is 1/16" smaller than you drain tubing (eg. 5/8" garden hose (drill 9/16" hole), or any size tubing, cut the end of the 'hose' at a 45degree angle and pull it into the container IT WILL BE TIGHT... cut it off square close to the containers wall...water proof. Put ball valve if necessary.
