The new EZ Drain Reservoirs use a gradual interior slope to allow the solution to drain completely without manually tilting the units. The EZ Drain makes maintaining your hydroponic systems hassle-free. The EZ Drain also includes molded volume markers in gallons and liters so you'll always know how much solution you have left. The basin of the 100-gallon White Eazy Drain Reservoir is gradually sloped, allowing liquids inside to drain without difficulty. After hobbyists attach a separately-available bulkhead fitting with an on/off valve to the reservoir, drainage is as simple as connecting a hose and watching it empty. The dimensions are 81.5 in x 30 in x 13.75 in. TRUCK SHIPMENT CLICK HERE
