5. Installation
The Phylrich ZIPXCART is designed for straightforward installation. However, if you are not experienced with plumbing, professional installation is recommended.
Required Tools (Not Included):
- Adjustable wrench
- Screwdriver (Phillips or flathead, depending on existing trim)
- Plumber's tape (optional, for threaded connections)
- Clean cloth
Installation Steps:
- Turn Off Water Supply: Locate the main water shut-off valve for your home or the specific shut-off valves for the shower. Turn them off completely to prevent water flow.
- Remove Shower Trim: Carefully remove the shower handle, escutcheon plate, and any other trim components to expose the existing valve body and cartridge. Refer to your shower fixture's manual for specific trim removal instructions.
- Remove Old Cartridge: Depending on your existing valve, there may be a retaining clip, nut, or screws holding the old cartridge in place. Remove these fasteners and gently pull out the old cartridge. You may need to twist it slightly to dislodge it.
- Clean Valve Body: Inspect the inside of the valve body for any debris, mineral deposits, or O-ring remnants. Clean the area thoroughly with a clean cloth.
- Install New Cartridge: Align the new Phylrich ZIPXCART cartridge with the valve body. Ensure any alignment tabs or notches on the cartridge match those in the valve body. Push the cartridge firmly into place until it is fully seated.
- Secure Cartridge: Reinstall the retaining clip, nut, or screws that hold the cartridge in place. Ensure it is securely fastened but do not overtighten.
- Reinstall Shower Trim: Reattach the escutcheon plate, handle, and any other trim components.
- Restore Water Supply and Test: Slowly turn the main water supply back on. Check for any leaks around the valve body and trim. Operate the shower handle to test both hot and cold water flow and temperature control.
6. Operation
The thermostatic shower valve cartridge automatically mixes hot and cold water to maintain a constant output temperature, even if there are fluctuations in the incoming water pressure or temperature. This ensures a comfortable and safe showering experience.
- Temperature Adjustment: Use the temperature control handle on your shower fixture to set the desired water temperature. The cartridge will automatically adjust the hot and cold water mix to achieve and maintain this setting.
- Flow Control: Use the flow control handle (if present on your fixture) to adjust the water volume.
Note: If your shower fixture has a temperature limit stop, you may need to adjust it to achieve higher temperatures. Refer to your shower fixture's manual for instructions on adjusting the limit stop.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your thermostatic cartridge.
- Cleaning: Periodically clean the visible parts of your shower trim with a soft cloth and mild soap. Avoid abrasive cleaners, as they can damage the finish.
- Mineral Buildup: In areas with hard water, mineral buildup can affect cartridge performance over time. If you notice a decrease in temperature control or flow, the cartridge may need to be removed and soaked in a vinegar solution to dissolve mineral deposits.
- Leak Checks: Regularly inspect around the shower valve and trim for any signs of leaks. Address any leaks promptly to prevent water damage.
- Annual Inspection: Consider having a qualified plumber inspect your shower valve and cartridge annually, especially in hard water areas, to ensure proper function and prevent issues.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water or inconsistent temperature | Hot water supply issue, cartridge clogged with mineral deposits, or temperature limit stop set too low. | Check hot water heater. Remove and clean cartridge. Adjust temperature limit stop on shower fixture. |
| Low water flow | Cartridge clogged with debris or mineral deposits, or water pressure issue. | Remove and clean cartridge. Check main water pressure. |
| Water leaks from handle or escutcheon | Improperly seated cartridge, damaged O-rings, or loose connections. | Ensure cartridge is fully seated and secured. Inspect and replace O-rings if damaged. Tighten connections. |
