How to Install Your SoftCell Portable Water Softener in Your Boat

For boating enthusiasts, ensuring a supply of soft water onboard is crucial for both comfort and maintenance. Hard water can lead to scale buildup in the boat’s plumbing system, reducing efficiency and potentially causing damage. The SoftCell Portable Water Softener offers a solution, designed for easy installation and exceptional performance. This guide will walk you through the steps to install your SoftCell Portable Water Softener on your boat, ensuring you have access to soft water throughout your maritime adventures.

What You’ll Need

Before starting, ensure you have all the necessary tools and components for the installation. Typically, you’ll need:

  • SoftCell Portable Water Softener unit
  • Standard garden hose fittings
  • Flexible/ Supply / Garden hoses (recommended to have 2) 
  • Mounting brackets (optional, for future permanent solution)


Step-by-Step Installation Guide

Step 1: Choose the Installation Location On Your Boat

Identify a convenient, accessible location for the water softener, preferably close to the water supply line. It should be mounted vertically, with enough space around it for easy access during maintenance and regeneration.

Step 2: Prepare the Water Supply Line

Turn off the water supply to your boat. If your boat is in the water, ensure the inlet valve from the external water source is closed. Attach the inlet hose of the SoftCell water softener to your boat’s water supply using the standard garden hose fittings. 

(Use Teflon tape to secure the connection and prevent leaks.)


Step 3: Connect the SoftCell Water Softener

Using the flexible hoses, connect the SoftCell unit’s inlet to the water supply line and the outlet back to the boat’s plumbing system. Ensure all connections are tight and secure to prevent leaks.

Step 4: Secure the Water Softener (Optional)

If you’re using mounting brackets, securely mount the SoftCell unit to a stable surface to prevent movement while the boat is in motion. Ensure the unit remains vertical and accessible.


Step 5: Flush the System

Before using the softener, flush the system by running water through it for several minutes to remove any debris or air. Check all connections for leaks and tighten if necessary. Note: for the first time after purchasing the SoftCell System you can just hook it up and use it. 


Step 6: Maintenance and Regeneration

For the average user, we recommend doing a regeneration every 2-3 weeks based on use and water hardness.

Installing a SoftCell Portable Water Softener in your boat is a straightforward process that can significantly enhance your boating experience. By following these steps, you’ll ensure your boat’s plumbing system is protected from scale buildup, and you and your guests will enjoy the benefits of soft water. Regular maintenance and timely regeneration of your SoftCell unit will keep it performing optimally for years to come.
