2nd Floor Laundry with Direct Drain & Pan Drain

Hello to all! Hoping to solicit some wisdom about my 2nd floor laundry. I am having my wood floors redone and my washing machine drains directly into a 2" drain pipe but is also sitting atop of a pan drain. I would like to get rid of the pan so the flooring guys can patch the hole in the wood floor but have the following questions:



1) Do I need a pan drain if I already have the direct drain?



2) If I don't need the pan drain, how can I seal off the drain under the wood floor?



3) Should I let the flooring team enclose the drain with wood flooring?


Pictures attached. Thanks!

Regards,

Patrick

Check your local codes to see if a pan is required in your area. Since the plumbing is already there I would keep it. It could really save you if the washer ever develops a leak.

Many codes do require a drain pan for 2nd floor laundry. It not uncommon for washers to leak, and you don't want a potential leak to end up ruining the floor/ceiling or more.

Thanks Zorfdt,

I'll keep the drain pan as a precaution against leaks and a faulty washing machine.

Regards,

Patrick

PilotDane & Zorfdt,

Thanks for the responses! I was told that a pan drain shouldn't tie into the main plumbing drain and if the p-trap dries up it can cause issues. Should I keep the pan drain and just ensure I pour water in it? Thanks!

Regards,

Patrick

You can put light mineral oil into the trap. Oil doesn't evaporate and it will stop sewer gasses from escaping. Or, pour some water in the trap if you ever notice a smell.
