    Hello dear specialists. There is a problem on my printing machine equipped with a Thermostating of the inking apparatus. The pressure constantly drops below 1.5 bar. I turn on the water pump and the pressure is back to normal around 1.5-2 bar. But two days later, the pressure is back on zero. Found a minor water leak in the pipe fixed it, but it didn't help. We examined the entire car every inch and there are no water leaks anymore. What should I do? Thanks.

    Hi, I had a similar problem. After removing the leak, we checked all hose clamps

    If there are no leaks in the hoses as you say you checked them sometimes it can be the auto air bleeders leaking but more likley it will be the expansion tank has either no or little air in it.
    The air pressure in the tank should be 0.5 bar with no water pressure in the system.
