Everyone is raped if they buy schedule 40 end caps over 4"! I mention on
our report tape #3 about building the giant rolled caps that you should look
at the 6" "drain caps" and not the pressure caps. Note that some drain caps
in this size are styrene and will not fit schedule 40 pipe. They got you
comin' and goin'. The drain caps were a friendly $7.00 each
