Neighbor just had their 5 HP submersible replaced. Original pump was a Grundfos stainless steel impeller and it lasted over 10 years. The one replaced after that had a thermoplastic impeller I believe and it only lasted 7 years, evidently the motor was good but the impeller was shot according to the well guy. I guess the $3000.00+ question is will a stainless impeller last longer than a thermoplastic for this type of pump (high head submersible)? These wells are about 750 ft deep so they are expensive to maintain. They serve multiple properties depending on output. I have a similar situation although my second pump is still OK with about 6 years on it. I live in my house where the other folks â€“ two houses are weekend or less second home folks.
