Today we ran the line for the gas from the septic tank and we got the water out...in other words, it was not quite as disgusting as yesterday.
It turns out that they have not had any water pressure in the bathroom we are now renovating in many years...you could not even run water in the sinks. We were talking about a work around for a while (cutting a new trench in the concrete was the first choice). Then I thought, "why don't they have pressure?" I backtracked through the system in 15 minutes and found that there were some rocks caught in this faucet which controlled the water pressure. 30 seconds later, problem solved. I am amazed they went many years without water for the bathrooms and cleaning when it took such a small amount of time to resolve it.
