Unfortunately we do not provide a repair service at all. You should have the pump replaced under warranty. See on the receipt how long HD will warranty the pump, if it is not longer in warranty with HD, then send us a copy of the receipt, name, address and telephone number and we will take care of the warranty.
you can contact us, CustomerService@BeckettUS.com or 888Beckett and take the option 2 for customer Service. We are in 8-5 Mo-Fri CST.
