Hello I have an Gitrac VHEF 80 pressured water tank installed. However the water pressure in my taps are now either really high (water splashes averywhere) or very low and water is just dripping out. What could be the problem? I don't see any pressure meter anywhere.

First a little more information. What are the cut bin and cut out points on your control box? What's your bladder tank charged at? What type of well and pump? Did your problem start all of a sudden or just come on slowly? The original question asks
How does well pump and expansion tank operate If you don't know here's how they work, (see image)
