even 18" is not reliable. my existing system is 18" inches with gravity drains and I get that blown out to be sure.
there is a drain plug at the end of every zone line and i will add a couple more in the system at low points. i wish i could get decent drain cocks. pvc plugs look pretty dubious to me.
