How to Install the Liberty SJ10 Sumpjet Water Powered Back Up Pump
Installing a water-powered backup pump, such as the Liberty SJ10 SumpJet, is a wise investment for homeowners who want to ensure the protection of their basements from flooding during a power outage or primary pump failure.
This backup pump utilizes the power of municipal water supply to provide an additional layer of defense in case the primary sump pump fails.
In this comprehensive guide, we will walk you through the step-by-step process of installing the Liberty SJ10 SumpJet, highlighting important considerations and providing expert tips for a successful installation. Let's dive in!
Step 1: Mounting the SumpJet to the Existing Discharge Pipe
To begin the installation process, you will need to mount the SJ10 SumpJet to the existing discharge pipe. Follow these steps:
Using the hose clamps provided, securely attach the SumpJet to the existing discharge pipe. Ensure that the unit is positioned in a way that allows the float level to operate a few inches above the turn-on level of the primary sump pump. For reference, consult Figure 2.
Tighten the hose clamps on the discharge pipe to ensure a snug fit.
Note: If the primary installation method described above is not feasible for your setup, refer to the alternate installation method outlined in the manufacturers installation guide.
Step 2: Hooking into the Municipal Water Supply Line
After mounting the SJ10 SumpJet, the next step involves connecting it to the existing municipal water supply line. Follow these guidelines:
- Shut off the municipal water supply before proceeding with the installation.
- Plumb the necessary tubing or piping into the municipal water supply line, ensuring compliance with local codes and jurisdiction requirements for backflow prevention.
- Install a union or other quick-disconnect fitting on both the water supply and discharge piping. This will allow easy access for servicing the pump in the future.
- Within 6 ft. (1.8 m) of the pump, install a dedicated shut-off valve on the water supply line.
- Use materials and methods approved by local plumbing codes for all water supply piping.
Step 3: Purging the Water Line
Before connecting the water supply line to the SJ10 SumpJet, it is crucial to purge the water line to eliminate any debris, solder, or pipe sealant. Follow these steps:
- Run water through the line to flush out any impurities.
- Check for any signs of debris, such as discoloration or particulate matter, and ensure that the water line is clear before proceeding.
Step 4: Connecting the Water Supply Line to the SharkBite
In this step, you will connect the water supply line to the SharkBite, a popular type of fitting known for its simplicity and reliability. Follow these instructions:
Cut the pipe or tubing end square, ensuring that there are no burrs or scratches within 1 inch from the cut end.
- FAQ: What should I use to cut the pipe or tubing end square?
Use a pipe cutter or a tube cutter for precise and clean cuts.
Mark the pipe or tubing 1 inch from the cut end to indicate the proper insertion depth. If you are using PEX tubing, make sure to use the tube liner in the end of the SharkBite.
For copper and CTS CPVC piping, remove the tube liner (use fingers or pliers).
Insert the tubing or pipe into the SharkBite through the release collar, allowing it to rest against the grab ring.
Push the tube or pipe firmly until it reaches the tube stop.
To ensure a secure connection, give the tubing or pipe a firm pull to check if it is properly seated. You should not be able to remove the tubing or pipe without using the release collar.
Repeat the above steps to connect the other end of the tubing or pipe to the inlet of the SumpJet. Ensure a tight and leak-free connection
Step 5: Installing the Check Valve and Discharge Piping
In this step, you will install the check valve and discharge piping to ensure proper water flow and prevent backflow. Follow these instructions:
Install a check valve in the discharge piping, preferably as close to the outlet of the primary sump pump as possible. This check valve will prevent water from flowing back into the sump pit.
Extend the discharge piping above the highest water level that your basement is expected to encounter. It is recommended to direct the discharge water away from the foundation of your home, preferably at least 20 feet (6 meters) away.
Use pipe hangers or straps to secure the discharge piping in place, ensuring it is stable and properly supported along its entire length.
Step 6: Testing and Adjusting the Float Level
After completing the installation, it is important to test and adjust the float level of the SJ10 SumpJet to ensure proper operation. Follow these guidelines:
Fill the sump pit with water until the SumpJet activates and starts pumping. Observe the float level during this process.
Adjust the float level, if necessary, to ensure that the SumpJet activates and deactivates at the desired water levels. Refer to the manufacturer's instructions for detailed information on adjusting the float level.
Test the SumpJet periodically to ensure its reliable operation and make any necessary adjustments.
Step 7: Restoring Municipal Water Supply
Once you have completed the installation and tested the SJ10 SumpJet, it's time to restore the municipal water supply. Follow these steps:
Open the dedicated shut-off valve on the water supply line to allow water to flow to the SumpJet.
Monitor the SumpJet during this process to ensure proper functioning and check for any leaks in the system.
If any leaks are detected, immediately shut off the water supply and inspect the connections. Tighten or reseal any fittings as needed.
Step 8: Maintenance and Regular Inspections
To ensure the long-term effectiveness of the Liberty SJ10 SumpJet and prevent potential issues, regular maintenance and inspections are essential. Follow these recommendations:
Periodically check the operation of the SumpJet by pouring water into the sump pit while the sump pump is powered off, and verifying its activation and pumping.
Inspect all connections, fittings, and piping for leaks or signs of damage. Repair or replace any faulty components promptly.
Clean the intake screen or filter to prevent debris from obstructing the water flow and impeding the pump's performance.
Follow the manufacturer's guidelines for any additional maintenance tasks specific to the Liberty SJ10 SumpJet.
By following these step-by-step instructions and adhering to the manufacturer's guidelines, you can successfully install the Liberty SJ10 SumpJet water-powered backup pump.
This reliable system will provide you with peace of mind knowing that your basement is protected from potential flooding caused by a primary sump pump failure or power outage.
Remember to consult the product manual and seek professional assistance if you encounter any difficulties during the installation process.
