FTR, I close the lid and flush.
I want to know if they actually went. I also want to know if urine is too dark and if stool is too hard or too loose.
I want to know what I am dealing with.
I also want to know what they would be flushing. Shoes, socks, pocketed toys, half a roll of TP, you know... preschool stuff.
I have a septic tank in rocky soil, mishaps get spendy really fast. My last big hit was $19,000
