Hi,

I plan to install dual-fittings floor trap for washing machine and sink outlet, with anti-odor and insects functionality.

My concerns are:

1. If I use floor trap with anti-odor and insects functionality, does it will impact on the outlet flow in general i.e. overflow as water drain from washing machine usually will be in high volume and high pressure. 

2. If I proceed to use dual-fittings floor trap with anti-odor and insects functionality, which type of floor trap is the best self-sealing or long-sealed? (see picture below)

Mine needs to use dual fittings i guess, as there will be 2 outlets coming from sink and washing machine. Now i sked already, overflow is high chance?
