How to Install Your SoftCell Portable Water Softener in Your RV

Traveling in an RV offers the freedom to explore without sacrificing the comforts of home, including access to clean and soft water. Hard water, rich in minerals like calcium and magnesium, can damage your RV’s plumbing system, appliances, and negatively impact your skin and hair. The SoftCell Portable Water Softener is designed to address these issues, providing soft water wherever your adventures take you. This guide will walk you through the steps to install a SoftCell Portable Water Softener in your RV, ensuring you enjoy soft water across all your travels.


Before beginning the installation, gather all necessary tools and components. Typically, you will need:

  • SoftCell Portable Water Softener unit

Installation Steps

Step 1: Identify the Installation Location

Find a suitable location for your SoftCell Water Softener. It should be easily accessible for maintenance and close to the RV’s water supply line. The area should also allow for the unit to be stored securely while driving.

Step 2: Connect to the RV Water Supply

Turn off the RV’s water supply. Locate the water inlet hose and attach it to the “in” port on your SoftCell Water Softener. Ensure the connections are secure by using Teflon tape on the threads to prevent leaks, then tighten with an adjustable wrench.

Step 3: Connect the Outlet Hose

Attach a flexible hose to the “out” port of the SoftCell unit, securing it with hose clamps. Connect the other end of this hose to your RV’s water system inlet. Again, use Teflon tape to ensure a leak-proof seal and tighten all connections.

Step 4: Secure the Water Softener

Secure the SoftCell unit in your chosen location. While some models may be designed to stand freely, securing the unit can prevent it from moving or tipping while the RV is in motion. Use brackets or straps if necessary, depending on your specific RV model and SoftCell unit.

Step 5: Test the System

Turn on the water supply and check for any leaks at the connection points. If leaks are found, tighten the connections further. Allow the water to run through the softener for a few minutes to activate the system. Test the water hardness using a test kit to ensure the softener is functioning correctly.

Step 6: Maintenance and Regeneration

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

Installing a SoftCell Portable Water Softener in your RV is a straightforward process that can significantly enhance the quality of your travel experience. Soft water can prevent scale buildup in your RV’s plumbing, extend the lifespan of your appliances, and improve your skin and hair health. With the SoftCell Water Softener, you can ensure that wherever your travels may lead, soft water will accompany you, making your journey even more enjoyable.
