How to install a household circulation pump
Household circulation pumps are important equipment to improve the efficiency of hot water circulation, especially in winter, which can significantly reduce the time waiting for hot water. This article will introduce the installation steps, precautions and common problems in detail to help you complete the installation easily.
1. Preparations before installation
Before installing the circulation pump, you need to confirm the following:
| Project | request |
|---|---|
| Power conditions | 220V AC power, independent socket required |
| Pipe type | Suitable for PPR, copper or stainless steel pipes |
| Installation location | Near the water heater outlet, avoid high temperature areas |
| Tool preparation | Wrench, raw material tape, screwdriver, level |
2. Detailed explanation of installation steps
1.Turn off water and power: To ensure construction safety, turn off the water heater inlet valve and main power supply.
2.Determine the installation location: Give priority to the return end of the hot water pipe, which is preferably 1-3 meters away from the water heater.
| Installation location | Advantages and Disadvantages |
|---|---|
| Water heater outlet | Easy to install, but the circulation effect is average |
| Return pipe end | High circulation efficiency, need to embed return pipe in advance |
3.Pipe cutting and joining:
- Use special scissors to cut the pipe to ensure a smooth cut
- Wrap the raw tape around the threaded interface for more than 15 turns
- The direction of the arrow on the pump body must be consistent with the direction of the water flow
4.Fixing and wiring:
- Fix the pump body with a bracket to keep it level
- Connect the power cord according to the instructions (usually three-wire system)
- It is recommended to install a waterproof junction box
3. Debugging after installation
| Debugging steps | Standard value |
|---|---|
| Check for leaks | No leakage within 30 minutes |
| operating noise | ≤45dB |
| Water temperature rising speed | Raise 5℃ in 3 minutes |
4. Solving common problems
1.Pump not running: Check whether the power is on and whether the fuse is blown.
2.Water flow is noisy: There may be air in the pipe, and the exhaust valve needs to be opened to evacuate it.
| Fault phenomenon | solution |
|---|---|
| Frequent starts and stops | Adjust thermostat sensitivity |
| The interface is leaking | Rewind the raw material tape |
| Overheating protection | Check the cooling environment |
5. Maintenance suggestions
- Check seal status monthly
- Clean water inlet filter quarterly
- No need to drain the water if it is not used for a long time in winter
- It is recommended to replace the bearing lubricant every 2-3 years
By following the above steps, you can complete the professional-grade installation of a home circulation pump. In case of complicated situations, it is recommended to contact professionals for installation and debugging.
