We offer a complete factory repair service for Flo King customers. Our trained technicians can restore your product to like-new condition, usually at a fraction of the cost of a new unit. Plus, we reinstate the warranty on all replacement parts.

Typically allow a few weeks for evaluation and repairs.

Send your disabled unit to: 

Attn: Repair Dept.
Custom Masters/Flo King Filter Systems
401 Lake Bennett Ct.
Longwood, FL 32750-6341 USA

A return authorization number is NOT required. But make sure to include your name, address, phone number, fax, e-mail and other contact information inside the box. Also package the unit securely (in the original box and packing, if still available) to prevent further damage during shipping. 

Clean pump in accordance with all shipping regulations. The Repair Dept. will not accept equipment that is covered with thick and/or difficult-to-remove chemical residues.

Upon request, a technician will contact you with an evaluation and repair estimate.
