I don't think a typical sink faucet (with an aerator) would flow that fast.The water meter should be spinning like a top at that rate, assuming it's the mechanical type I'm familiar with.If the property is three houses with one meter, I'd say there is likely a broken pipe underground somewhere between them.

We also seem to have similar backgrounds as I have a mechanical design engineer background.

Capex  should also be factored in as long term expenses for roof and mechanical items.  

My dad was a mechanic, and some of my best memories as a child were just being with him, watching him work.  

For most of you who do not know me, I love woodworking and working on anything mechanical, especially cars.

You need all new electrical,water, mechanical, sewer line, siding etc.  

The sale includes two Haas CNC machines and a literally every single welding and fabrication tool/mechanism known to man.

I wear an orange Field and Stream hat, blue jeans, navy blue mechanic's shirt.

Have him provide a SOW of what the costs are for his labour for each part, and figure out a mechanism where you can fire him if he isn't performing, and only owe him for the labour for the parts he has completed correctly.

Do you know any Day Labor guys or Carpenters or Electricians or AC mechanic types?
