Connecting pvc to threaded galvanized drain pipe.
Brass steel and galvanized pipe that are not used in residential waste systems as often are either a threaded or soldered connection which gives a moderate amount of mechanical resistance to movement.
Abs to pvc threaded fittings.
Insert the pvc pipe into the other end tighten the clamp and you re done.
One inexpensive method of connecting abs to pvc drainpipes is to use male and female fittings.
Apply pipe thread tape before screwing them together and then glue the pipes into the fittings using the proper cement.
Arrange the fittings so the water flows past the threads on the male fitting not into them.
Pvc pipe is glued and the glue actually melts the two pieces of pipe causing a chemical weld.
