Good day I have a problem with my hydroelectric, since it turns on every 10 minutes it loads up to 40 psi and cuts in 20 psi, all that is normal, but without using any key the pressure drops gradually during the 10 minutes and returns to turn on. I already checked the internal camera and it doesn't leak I put and calibrated the camera at 18 psi Turn off at 40 Psi and turn on at 20 psi I'm not leaking Even closing the key that distributes to the house drops the pressure Any advice you can give me please Thank you Regards!

Hello if you are fully sure that there are no losses in the pipe or in the tap, what may be happening is that the internal membrane of the tank has been punctured, or some ring of the same; if an air whistle is heard, it is surely an arosello Cheers !
