Introduction
The Hydronix Shok Blok SB-FPV-70 is a specialized pressure regulator protection valve designed to safeguard Reverse Osmosis (RO) systems and other water filtration setups. It is engineered to limit incoming water pressure to a maximum of 70 PSI, preventing potential damage to sensitive filtration components from high or fluctuating water pressure. This device features convenient 1/4-inch Quick Connect (QC) ports for straightforward installation into existing systems.
Safety Information
Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions could result in property damage or injury.
- Water Supply: Always turn off the main water supply before beginning any installation or maintenance.
- Pressure Check: Ensure the incoming water pressure does not exceed the maximum rated pressure of the valve (70 PSI) for prolonged periods without additional pressure reduction if necessary.
- Leak Detection: After installation, carefully check all connections for leaks. Tighten connections as needed.
- Proper Tools: Use appropriate tools for installation. Avoid overtightening connections, which can cause damage.
- Temperature: Do not install in areas where the water temperature may exceed the valve's operating limits.
Product Overview
The Shok Blok SB-FPV-70 is a compact, inline pressure limiting valve constructed from durable polypropylene. Its primary function is to provide a consistent and safe operating pressure for your water filtration system, thereby extending the lifespan of filters and membranes. The 1/4-inch Quick Connect ports allow for tool-free connection to standard 1/4-inch tubing.

Setup and Installation
Follow these steps for proper installation of your Shok Blok SB-FPV-70 pressure regulator valve.
Before Installation:
- Identify the incoming water line to your RO or filtration system. The Shok Blok valve should be installed on this line, before any sensitive components like the RO membrane or carbon filters.
- Ensure you have 1/4-inch tubing for connection.
- Turn off the main water supply to the area where the installation will take place.
- Relieve any existing pressure in the water lines by opening a nearby faucet.
Installation Steps:
- Prepare Tubing: Cut the 1/4-inch water supply tubing at the desired installation point. Ensure the cuts are clean and straight to prevent leaks.
- Connect Inlet: Insert one end of the prepared 1/4-inch tubing firmly into one of the Quick Connect ports on the Shok Blok valve. Push until it bottoms out, then gently pull back to ensure a secure connection. This will be the inlet side.
- Connect Outlet: Insert the other end of the tubing (leading to your filtration system) firmly into the remaining Quick Connect port on the Shok Blok valve. Push until it bottoms out, then gently pull back to ensure a secure connection. This will be the outlet side.
- Secure Valve: Position the valve securely, ensuring it is not under strain from the tubing.
- Restore Water Supply: Slowly turn on the main water supply.
- Check for Leaks: Carefully inspect all connections for any signs of leaks. If a leak is detected, turn off the water supply, disconnect the tubing, re-cut the end of the tubing if necessary, and re-insert it firmly into the Quick Connect port.
Operating Instructions
The Shok Blok SB-FPV-70 is a passive device that automatically regulates water pressure. Once installed, it requires no manual adjustment or operation. It will continuously limit the downstream pressure to approximately 70 PSI, protecting your connected filtration system. Ensure that the water flow is not obstructed and that the valve is not subjected to pressures exceeding its design limits.
Maintenance
The Shok Blok SB-FPV-70 is designed for minimal maintenance. Regular checks are recommended to ensure optimal performance and system integrity.
- Visual Inspection: Periodically inspect the valve and its connections for any signs of wear, cracks, or leaks.
- Flow Rate: If you notice a significant drop in water flow through your filtration system, check the valve for any potential blockages or issues, although this is rare for a pressure regulator.
- Replacement: While the valve itself does not have a scheduled replacement interval like filters, it should be replaced if any damage is observed or if it fails to maintain the specified pressure.
Troubleshooting
If you encounter issues with your Shok Blok SB-FPV-70, refer to the following table for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leak at Connections | Improperly seated tubing; damaged tubing end; damaged O-ring in QC port. | Turn off water supply. Disconnect tubing, re-cut end cleanly and squarely, then re-insert firmly. If leak persists, inspect O-ring or replace valve. |
| No Water Flow or Very Low Flow | Main water supply off; valve installed backward; severe blockage within valve (rare). | Check main water supply. Ensure valve is installed with correct flow direction (if indicated). If flow is still restricted, remove valve and check for internal blockage. |
| High Pressure Downstream (above 70 PSI) | Valve malfunction. | If incoming pressure is high and the valve is not reducing it, the valve may be faulty. Replace the valve. |
