So i just bought a used emperor 400 it moves water just not that fast or well. Can a impeller lose it's magnetism??? if so i'll jsut buy another and we'll be good. anything else i can do its an older model
They make a little round brush that fits right down in the hole.CHOMPERS;2482638; said:Take the impeller out and check for lint build up around the shaft (yes it's weird but I have seen it several times). Also clean out the impeller housing. Growth in there adds friction to the impeller which slows it down.
