I have relatively new setup and the valve is located all the way down by the sump pump as it should to prevent the back flow....however, I am a bit annoyed by the sound of the water flowing back along the pipes..... I have about 6 feet horizontal pipe to the exterior wall and another 7 or 8 feet down to the pit. All are 1.5 inch Would it be advisable to install another one-way valve right on top of the pipe ? I know this is purely "cosmetic" since there is nothing strange about water flowing down an 8ft vertical pipe and my only objective is making it silent (yes...I am very anal when it comes to noises and sounds LOL).... just worry that two valves along the path my impact the pump ability to work efficiently, Any input ?

What would cause a submersible well pump to turn off before reaching cut in pressure? Symptoms. Standing in shower have good pressure then pump/water turns off. Wait a few seconds and pump and water come back on. Have set and reset cut on and cut off pressure and have also adjusted water tank pressure to 2-4 psi below cut in pressure. the only way I can get water to stay on continuously now is to let most of the air out of the tank (say down to 5 or 10 psi). Water Pressure in the shower is sacrificed doing this but otherwise everything else seems to be working correctly. Pump does NOT appear to be short cycling either before or after adjusting the tank pressure (at least not significantly..... I think). One note of mention that may be a clue is that for some reason water pressure at the gauge continues to rise by as much (or more than) 20 psi AFTER the pressure switch cuts out. I know the switch is disconnecting and therefor the pump is not pumping. Any ideas?
