You’re very lucky I’ve done some serious damage over here you’ll see …I was intending to renovate this home anyway but I’m pissed offThat sux man…I did something very similar not to long ago…I was filling my 55 gallon barrels slowly because I only get about a gallon minute return on my water…Just like you I got to multitasking and forgot all about it for awhile until I saw water running underneath my wall…what a fucking mess and another time my timers for auto watering were set to auto on instead of auto off and the water just ran all night until the barrels were empty…thank god my flood tables held pretty much all the water and I just had to vaccum all the water out of the 4 flood tables…Needless to say my plants got a real good nute flush
