When my ex husband lived here, twice he went outside and did something to force the septic sprinklers to come on. I assumed he turned the breaker off and then on again. Sometimes I "loose" my sprinklers because they were placed in an area that's hard to mow so to find them, we'd activate them and follow the water. Well, while clearing a part of the yard I found one of the sprinkler heads and I'm so excited because this is the first time since a couple months after they put them in, that I've got the area where I can mow around it. There were a lot of fallen trees, ruts in the ground, thorny vines and giant ant beds. Well I've got that all taken care of and can get over there with the riding mower now so I can keep it kept up. I'm trying to set the sprinkler head off to see if it's going to spray the newly cleared area. I threw the breaker off then on, that didn't do it. I went to the septic tank and there is only one button called reset and I pushed it and nothing happened. So I called the septic company and he said to remove the concrete cap, remove some hose and let it drain into the tank and that should force it on. Then when I've got the spray adjusted, throw the breaker off, reattach the hose, put the concrete cap back on and turn the breaker back on. I told him my ex husband would go out and just do something and they would come on and the septic tank guy said he didn't know what I was talking about. So, does anyone know where this magic button might be to make the sprinklers come on? I don't know if I can lift that concrete cap off of the septic tank.
