In older houses (like mine) many sewers are plumbed with 2ft clay tiles, one
end has a bell shape and the male end fits in the bell.....tree roots can
readily penetrate this type of drain line.....luckily the neighbors Popular
tree decided to croak and no longer plugs my line annually although said
tree just dropped a rather large branch on another neighbors roof (Big
tree)......the sweet lady whom originally planted the trees (since deceased)
in 1966 had not idea such little twigs could get so big....Rod
