Why Rebuild Your 975XL?
-
Pass Annual Inspection: Most jurisdictions require annual backflow testing — a worn unit will fail
-
Stop Water Waste: A leaking relief valve can waste hundreds of gallons per day
-
Protect Water Supply: A properly functioning RPZ prevents contaminated water from backflowing into the potable supply
-
Save vs. Replacement: A rebuild kit costs a fraction of a new backflow preventer assembly
Frequently Asked Questions
Q: Will this fit my 1" Zurn 975XL?
A: Yes, this kit fits all 3/4" and 1" Zurn 975XL and 975XL2 models.
Q: Is this a genuine Zurn kit?
A: This is a high-quality aftermarket replacement kit manufactured to OEM specifications.
Q: Do I need special tools to install this kit?
A: Basic hand tools are sufficient — typically a screwdriver and adjustable wrench. The check modules unscrew from the valve body.
Q: How often should I rebuild my backflow preventer?
A: Typically every 5 years, or whenever it fails annual certification testing. More frequent in areas with hard water or high chlorine.
Q: Does this include the check module assemblies?
A: This kit includes rubber components (discs, diaphragm, O-rings) — not the plastic check modules themselves. If your modules are cracked, you'll need complete replacement modules.
