Hello. My washing machine drains directly before the tub drain in the adjecent bathroom (same line). I wish to filter the water exiting the washer with a trap, to prevent lint from entering the main sewer line, and reclogging. I was thinking of installing a utility tub, and extending the waher drain line with a trap to go into the tub, and then reconnecting the tub to drain to the original spot where the washer's drain tube is now connected. Does this sound feasible, and how much higher does the bottom of the tub need to be in relation to the high spot of the drain pipe it will be fitted to?

1. a trap will not filter the waste water...it is not meant to!
2. if you do not already have a trap on this line you should install one. it's purpose is to prevent foul sewer smells from entering your home. the water 'trapped' in the trap acts as a barrier.
3. the bottom of a new utility tub would need enough clearence
for the waste connection and a trap. anything extra is a bonus
