Too much soap is normally the culprit but not cleaning off all the food before putting the dishes in will cause the drain to become blocked and bad things happen. 

@Ramon Smothers Based on your assessment description, I would bank that the issue is in fact a leaky drain pipe and not the water lines.

NOPE - I had faucet off and new one on and then the drain piece broke, actually fell out bc of the pressure I had gently applied and was already broken anyway - just waiting to fall apart in my hands.

I do have a bit of cash I can bring to the table  which should help in partnerships, but not quite enough to be bringing all cash to the table, nor do I want to bring all cash to completely drain my capital.

My previous secretary manages our "production" lines, aggregate production, motor shop, and supply chain, then she graduated to 3 projects (20-30 people per project) doing it only by phone and bi-weekly reports and one foreman meeting each week, but those are more easy, just doing roads and small structures like drains and ditches.

She's emotionally drained right now from this property or dealing with the bank or whatever lead to her falling behind.

Had to replace the main drain (lateral from the house) to the main in the street.Hired a Pro to perform trenchless, sure glad I did. 

The units I used were designed to install under a standard kitchen counter (24in deep), so the back of the unit was not just a flush panel, there was recesses to account for hoses & drains on the washer, and space to route the dryer vent.My units were not much more than I would have spent for comparable set of units, but I did have to order them.

As for the separation, I'm no expert but I think it's a possibility that the previous owners started a french drain project but gave up..How much money would you expect a finished basement with added bath and structural fix, gutted and redone rooms, complete conversion from drop ceiling to drywall, an expanded kitchen/reno, and added bathroom to the main floor, cost?

Treat with Termidor on the outside perimeter.On the inside, treat with Phantom, around pluming drain and supply protrusions, window sills, behind electrical plates, door thresholds.Phantom: http://www.amazon.com/Phantom-Termiticide-Insectic...Termidor: http://www.amazon.com/Termidor-SC-Termiticide-20-o...This one two punch is very effective.
