6 hand bays, whenever all handbays are busy, when one switches over to rinse, it continues to dispense soap and not a clean rinse. Anyone know what the issue is and how to fix it? This is not an issues when 2 or 3 bays are in use.
On my 5000 d & s car wash, i can only get 20 lbs of pressure on the output side of the pump. This worked fine before shut down for cold weather, issue has been since we tried to come back up after shut down. Any ideas on how what might be causing this? Thanks for your help.
