Yes sir, there is a check valve for the supply line. I just didn't connect everything before the pic was taken because I neede to move it to the tent. It's in the tent now but I haven't hooked the drain and fill lines to the res yet. I ran out of time yesterday and I won't have plants in it for another couple of weeks so I'll get that part taken care of between now and then.
