Hi, i am looking for a little assistance in an issue at the car wash i am working at. i have a foaming spray arch and yesterday it started making a buzzing noise at the top right of the arch. the solenoid piece up top had drastically worn and today upon test runs the arch itself turns off any water or chemical that passes through it but the air pressure is staying on which is causing the arch to constantly use up air pressure inside the tank in the back. this issue than causes the tank to get to hot and allows me to not run. i believe the issue is a the solenoid valve but after changing it the issue has persisted and not stopped . any tips or help would be greatly appreciated.
