1. Introduction
This manual provides essential information for the proper installation, operation, maintenance, and troubleshooting of the Taco 00 Series Integral Flow Check Kit, model 006-047RP. This kit is designed as a replacement part for select Taco 00 Series circulator pumps that feature an integrated flow check. Please read these instructions thoroughly before proceeding with installation or maintenance.
2. Safety Information
WARNING: Failure to follow these safety instructions could result in serious injury or property damage.
- Always disconnect power to the circulator pump and associated equipment before attempting any installation, maintenance, or service.
- Allow the system to cool down completely before handling components, as hot water can cause severe burns.
- Drain the system completely before opening any plumbing connections to prevent water damage.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure all electrical connections are made by a qualified electrician and comply with local codes.
- If you are unsure about any part of these instructions, consult a qualified HVAC technician.
3. Setup and Installation
This section outlines the steps for replacing the integral flow check within your Taco 00 Series circulator pump.
3.1. Tools Required
- Adjustable wrench or pipe wrench
- Screwdriver (if applicable for pump housing)
- Bucket or pan for draining water
- Teflon tape or pipe sealant (optional, for re-sealing connections)
3.2. Installation Steps
- Prepare the System: Turn off the power supply to the circulator pump at the main breaker. Close any isolation valves upstream and downstream of the pump. Allow the system to cool.
- Drain the Pump: Place a bucket or pan beneath the circulator pump. Carefully open the drain valve (if present) or loosen a union connection to drain the water from the pump and surrounding piping.
- Access the Flow Check: Depending on your specific Taco 00 Series model, the integral flow check is typically located within the pump housing or a removable section. Refer to your pump's specific diagram for exact location. You may need to remove bolts or loosen a union to access it.
- Remove Old Flow Check: Carefully extract the old integral flow check assembly. Note its orientation for correct installation of the new part.
- Install New Flow Check: Insert the new Taco 006-047RP Integral Flow Check Kit into the pump housing. Ensure it is seated correctly and oriented in the same direction as the old one to allow proper flow.
- Reassemble and Refill: Reassemble any pump housing components or union connections. Tighten all connections securely. Slowly open the isolation valves to refill the system, bleeding air as necessary.
- Restore Power: Once the system is refilled and all connections are secure and leak-free, restore power to the circulator pump.

4. Operating Instructions
The integral flow check operates automatically within the circulator pump. Its primary function is to prevent gravity flow in open or closed hydronic heating and cooling systems, ensuring that heated or cooled water circulates only when the pump is running.
- Normal Operation: When the circulator pump is active, the flow of water opens the check valve, allowing circulation.
- Pump Off: When the circulator pump is off, the spring-loaded mechanism of the flow check closes, preventing unwanted thermosiphon (gravity flow) and ensuring efficient system operation.
After installation, observe the system for proper operation. The circulator should run smoothly, and water should flow as expected through the system when the pump is active. There should be no signs of leaks around the pump or connections.
5. Maintenance
The Taco 006-047RP Integral Flow Check Kit is designed for long-term, maintenance-free operation once properly installed. However, periodic checks of the overall circulator pump and system are recommended.
- Annual Inspection: Annually inspect the circulator pump and surrounding piping for any signs of leaks, corrosion, or unusual noises.
- Flow Check Functionality: If you suspect issues with gravity flow or improper circulation when the pump is off, the flow check may need inspection or replacement. This typically involves disassembling the pump as described in the installation section.
- System Water Quality: Maintain proper system water quality to prevent scale buildup or corrosion, which can affect the performance of the flow check and other system components.
6. Troubleshooting
If you experience issues after installing the replacement flow check, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No flow or reduced flow when pump is running | Flow check installed backward; debris obstructing valve; air in system. | Verify flow check orientation; inspect for debris and clean; bleed air from the system. |
| Gravity flow (heat/cool transfer when pump is off) | Flow check not closing properly (debris, worn spring, incorrect installation). | Inspect flow check for debris or damage; ensure correct installation. If damaged, replace the kit. |
| Unusual noise from pump area | Debris in flow check; worn pump bearings (unrelated to flow check); air in system. | Inspect flow check for debris; bleed air from the system. If noise persists, consult a technician for pump inspection. |
| Leaks around pump connections | Improperly tightened connections; damaged gaskets/O-rings. | Ensure all connections are tight; replace any damaged gaskets or O-rings. |
If troubleshooting steps do not resolve the issue, it is recommended to contact a qualified HVAC professional.
