Even if the greese does not clog the drain in your house, it can and dous
cause backups in the municipal sewer system. Call city hall and they will
encourage you not to do it as well. I often see short articals in my city
newspaper explaining how greese dumping is bad for the city.

I don't fry much so the cup a month I dump is not a problem but it sounds
like your dumping a lot more than that. If you insist, you need to run the
hot water a lot longer than you would think to flush the greese all the way
to the street before it thickens or pools. Else it will accumulate on the
walls of your drain pipe requiring a snake to ultimately clear it. If you
have a cleanout near the kitchen sink on the outside of your house, you
should run a garden hose down it every so often to act like a snke to clear
the debris.

WRT a dishwasher, It is the normal practice to connect the drain to either a
spot on the garbage disposer or to a sanitary tee before the P trap but you
also need an air gap before it, If the drain clogs, the dishwasher water
will flow out the air gap overflow into the sink basin instead of the
connection.

Every so often my kitchen sink clogs up from fat / grease residue from
frying and the
like. I clear it with boiling water but it is a pain when it happens.

What I want to do is route my dishwasher drain through my sink drains to
get a good
soapy water flush through every day.

MY sink P trap is at the right end of the double sink with the dish washer
on the
left side. So I thought I could just Tee in on the left end in order to
flush all the
lines.

Anyone see any problem with what I want to do??




Thanks for the response.
