There is water coming from the pressure relief valve, is that normal?

"Yes, a boiler is a pressure vessel. When pressure gets too high, the boiler will lower this by releasing water through the pressure relief valve. The installer of the boiler should have attached proper drainage."

Water is constantly coming out of the relief valve. Is this a problem with the relief valve? When I raise the relief valve, hot water comes out, and when I lower it, it stops, but after that, water continues to come out.
