"that is what back flow preventers are for, similar to a check valve, the city system SHOULD be at or above 60 lbs to prevent any contamination from getting a foot hold inside the pipes. it is required around ohio to have these check valves/ backflow preventors installed up stream of the meter and is usually the citys equipment (some do charge a feeuntill it is paid for though depending onn city charter & regualtions.)
anyhow there is a good concern about certain terrousts activities that most people are not aware of and that is pne of the primary reasons for higher pressures to KILL BACTERIA which could be introduced and prevent any from taking any footholds."
Uh, yeah, it doesn't work like that. The higher pressure has nothing to do with bacteria's ability to live or contaminants ability to spread. Filtration and chemical treatment (chlorine) is how we handle the impurities. The backflow device functions to prevent backflow but is not dependable enough to be used to prevent backflow in a system with dual feeds such as when you have a well feeding your plumbing AND the city supply. We do not want the risk of some yahoo backfilling the city system with his well water.
It is not typical in Washington to have a backflow prevention device on every water service. It is only required under certain circumstances such as when a sprinkler system is installed. So yes, your neighbor can likely pump nasty water backwards into the city system if he is so inclined and is willing to do some simple plumbing and pumping. Yet another argument to maintain your private well system instead of switching to city water.
