Water pressure problem with boiler
I have a vaillant Eco Max 828. I filled the water pressure to the max (in error!!) Pressure valve hit the red!! I turned the valve off, water gushed out of release pipe outside. Pressure bar dropped to 0. Now , when I add water , using water valve tap, pressure bar is not going up. Should I keep trying to add more water , as not sure how much came out?
