Orders that ship directly from a manufacturer normally have a firm shipping estimate but those dates are subject to change due to manufacturer production, inventory or shipping. We do our best to estimate ship dates but orders shipping directly from the manufacturer can have unexpected delays.

Once your order is placed with the manufacturer, it may not be able to be cancelled even if it hasn't shipped yet.

Special Case Shipping Rates
Please note that shipping rates are subject to change at any time. We reserve the right to charge an additional fee in addition to the regularly advertised shipping fee for shipping to remote areas not easily accessible by typical freight carrier means (i.e. islands only accessible by ferry). If your order falls into this category, you will be notified upon receipt of your order, and have the option to complete the purchase with additional fee or to cancel the order. Please note, these instances are very rare, as most locations are reachable by regular freight. If you have any questions, please contact us!

Typical Installation:
Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance with the manufacturers' instructions and the latest edition of the Uniform Plumbing Code. The assembly shall be installed with sufficient side clearance for testing and maintenance. The Zurn 1-500XL may be installed in any position. If installed in a pit, vault, or inside application, specify the "SC" sealed cage option. Multiple installations are recommend for wide demand variations or where the desired pressure reduction is more than 3 to 1 (i.e.: 150 psi inlet reduced to 50 psi outlet). Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verify correct pressure setting.
Standards Compliance:
ASSE Listed 1003 (1/2" thru 2 1/2"); cUPC Listed (1/2" thru 2"); CSA Certified B356 (1/2" thru 2"); City of Los Angeles Approved (1/2" thru 2"); NSF/ANSI/CAN 61 and 372
Features & Benefits:
- High Flow Capacity: Designed for industrial water lines and commercial water systems with superior flow performance.
- Thermal Expansion Protection: Direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion.
- Balanced Piston Design: Enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.
- Flexible Installation: Can be installed in any position with accessible maintenance without removing the body from the line.
FAQ
Q: Can the Wilkins 1-500XL be installed in any orientation?
