Getting out from underneath the high interest credit cards charge is vital.

I went to Cal Poly and studied Architectural Engineering so I heard about some local soil induced foundation issues from my professors.

I realize now I should have hired someone less familiar with the area, (a GIG engineer) since they would have used the proper setbacks and parking allowances per the Development Code for the vacation area and would not have cared about the normal zoning.I did hire a remote engineer to do the soils report.

If you don't understand Brownfield properties, Benzine contamination, quarterly soils testing - nobody does - hire a competent environmental firm.

Tenant in my Washington state rental moved out and we find out an active leak underneath the kitchen sink.

There was so much grease in the plastic drain pipes underneath the house, the weight of the grease caused the plastic drain pipes to bow, the drain pipes snapped of at a joint and the entire underneath of the house was flooded with the stinkiest grease and odor anyone could not imagine.

They look under the hood and crawl underneath and just stare at something in hopes that they see something major out of place but don't actually know how to look for things that prove the car wont break down 2 months after they buy it. 

The only 'sure' way is to correct the problem underneath the house.Although you're right that is a good quick fix....

They weigh tons fully loaded.If that's the situation, you will need to address the soil compressing the line or install a line designed for this environment.Talk to a plumber about it and see what your options are.The water line next to it seems unaffected, but might also be leaking. 

I read about the soil problem in the North East side of SA, and will definitely look out for that.
