I have to descale my tankless water heater. I've lost a bit of flow on the hot side apparent and its affecting the water pressure ion the shower.
I have what I need but I didn't want to go spend the only on a pump if I didn't have to. I went to my dads house and he has a half horse sump pump he said I could use. Now I'm not sure but I'm afraid that it could be too much flow/pressure to do the descale.
Can you cause damage to the unit by using too powerful a pump or should I be ok using the sum pump?
