Pond Boss Forums INTRO Questions & Observations Ok, I dont get this siphon stuff

Ditto tough weekend here. The well/pump that feeds our house is acting up - pump won't deliver over about 55 psi without (somehow - pressure safety switch using wrong value?) shutting itself off (fortunately horse barn and water are a separate well; cattle drinking pond water from hydrant below the dam). Then it turns back on when it feels like it. We put in a new P-switch and have (probably) ruled out electric supply problems; I currently have things running in a reduced pressure range (42-50 psi vs usual 40-60 psi) until we can assemble all possible spare items we could use and then pull/replace the pump. All in about 400% humidity
