Works great

Great irrigation box I used to place my submerged pond pump within. Sturdy with a great top grate!

Very pleased with the sturdiness of the shell and top grid, *BUT* there is definitely a manufacturing precision failure in matching the side screw-in inserts to the size of the pre-cut hole. Poor fit. There are way too many gaps. I had to use silicone caulk so it would not leak. Some of the gaps were so large it took three layers to get them sealed. Thankfully I had read of this issue in other reviews so had a small tube ready. I used 4" solid corrugated flex tubing. It fits over the basin's side tube flanges. The fit is NOT secure, so plan to caulk bottom crescent of the corrugated tube to prevent too much leakage out the bottom lip. Also purchase stainless steel short screws to attach the pipe to the male flange so it stays connected.I would NOT recommend using 3" piping even though they say it 'fits'. 4" slips over the flange so water flows out onto/into the pipe. A 3" would have to be caulked or glued to the INSIDE of the side flange, creating a greater possibility of leaks.I purchased two basins, one using the top flat grid that comes with it to receive a hefty flow of water that runs off a driveway, surrounded it with drainage gravel over weed fabric.The 2nd is installed directly under a downspout. We're in Florida, so have daily heavy rains. To be sure there was not a splash issue, I also bought the 12x12 sloped top grid. It replaced the top grid that came with the basin. (I wish they offered that duo as a combo!) Very pleased with the result. No splashing on side of house.There are weep drain holes in all for corners, but they need to be punched out. Easily done, flip it over at tap using a small flat tipped tool. No drilling necessary.To be extra sure no mulch or small leaves entered the buried corrugated pipe system, I also purchased 12x12 filtration netting inserts. Very pleased with the combo!! See images.

Solid construction, good choice for my project!

Works Great easy to install good quality

We have used prior versions of this unit. This is the "New Version," so I figured there were improvements over the prior version. The outlet adapter slots (4) around the perimeter don't line up and leave large unsealed sections where water leaks out. Although it should not be a huge issue, it will saturate the soil around the basin where water can escape during a difficult storm. The manufacturing seems low quality, given the poor fit. I think the manufacturing cost savings are the "improvements."

These are well built and do a great job. Installed three of them in our ditching/french drain system.
