I have a Honda GX120 water pump for use at camp. I set it up in the spring and remove it the fall. Our lake is high in iron and each year the scale builds up inside the pumphead.
Have you any opinion on spraying the inside of the pumphead with vinegar or something like a CLR product to remove this scale?
One season it was so bad the pump was actually seized right up and I had to send it off for cleaning so the issue is fairly serious.
