When your water pump fails, downtime isn’t an option. Our commercial water pump rebuild services restore industrial, oil & gas, raw water, and marine pumps back to factory spec, usually in just 1–2 business days. Whether you’re keeping a fleet moving, restoring a classic, or powering through the next job, we’ll get your pump back up and running: dependable, dialed-in and done right.
Fast 1-2 Day Turnaround + Family-Owned Backed by 40+ Years Experience + Built Like It's Ours Tough, Tested & Warrantied
If it keeps you running, we keep it alive.
We’re a second-generation industrial water pump repair shop in Houston, built on decades of experience and a reputation for fast, factory-spec water pump repairs.
Our gas & diesel water pump repair process is designed for everything from long-haul trucks to field compressors pulling double shifts. If it cools your engine, we can bring it back—usually in 72 hours or less. Every unit gets stripped, blasted, dipped, machined (if needed), resealed, and bench-tested to outlast what rolled off the line.
Our name’s built on fast turnarounds, ruthless quality control, and a knack for rebuilding hard-to-find or discontinued pumps. Back from WaterPumpKit.com? Good. Same family. Same handshake.
