I have been told that I should not use a "P" trap in a washing machine drain line due to the water in the "P" trap being forced out when the washing machine dumps. But should use a "barrell" type trap.
Any comments?

Hi Wramer1.
If you have an individual vent or a mechanical vent associated with the washing machine drain then you will want to install a PTRAP.
If you are in Maine or any other state that has similar codes then you can install a DRUM TRAP (barrel type) if you are within say 5 feet or less of a waste/vent stack.
95% of states use the PTRAP and individual vents here... :)
If you'd like more info. On how to pipe up a washing machine with vent and trap just let us know.
