No car wash operator wants to lose or frustrate customers because of a weak vacuum with bad suction. If you’re having vacuum performance issues and problems with suction loss, you may have a vacuum leak. There are several common problem spots to check.
Check Air Flow
Make sure that the vacuum hose is in good working order and is not clogged, so that air flow is not restricted. Also, keep the filter bags clean. Proper air flow creates the suction that allows the vacuum to work. If the bags are dirty, air struggles to filter through the bags. Shake out and wash the bags regularly.
Next, check the gaskets on the doors and under the motors. Be sure that the door gaskets are creating a tight seal, as it is common for these gaskets to get dirty. Check that the motor gaskets are creating a seal and are in working order. Vacuum gaskets can become damaged or compressed over time, causing the vacuum leak. Replace the worn gaskets or clean dirt buildup and your vacuum should be well sealed.
To help test performance, you can also purchase a vacuum test gauge and a vacuum check. The test gauge measures vacuum pressure inside the hose, and the higher the pressure, the better the suction. The vac check is a small cap that instantly seals off the motor and prevents suction loss in case of a vacuum motor failure.
Maintaining your vacuum is necessary to keep customers happy and bring in revenue. If you know how to check for vacuum leaks, you can prevent issues so customers have the same great experience every time they visit your wash.
