Hello. I am getting ready to replace my ~20 year old dishwasher and took a look under the kitchen sink to find a separate drain for the dishwasher (dishwasher rubber discharge hose connected to copper pipe in Photo1). I also took a look in the crawlspace under the kitchen where these two pipes pass through the floor. There are p-traps on the sink drain and dishwasher drain underneath the floor before they connect into the main stack.
1. Should I continue to use this separate drain line? or use the dishwasher drain connection on the garbage disposer and cap the dishwasher drain line?
2. Is there any benefit to having a separate dishwasher drain line?
Thanks.
