A friend of mine changed his impeller after 2 years (496 ho) and when he started it up he had no water pressure. Turns out he needed to replace his pump housing. I guess some sand worked a nice groove in the housing and he could not make a seal so he needed to replace the housing ($400). Is this
a common problem? I will be replacing my impeller after this season (2 year old 496 mag) and hope i don't have to replace more then just the impeller.
Thanks Johnny
