RV Water Softener and Deionizer

Installing an Automated Water Softener and Deionizer in an RV
Article Date: August, 2017

Installing the Equipment

I began by preparing the brine tank. The brine tank holds all of the solar salt that will be used to create the salt brine that will be used to regenerate the water softener. Before adding salt, I removed the top cover from the brine well. There is a float valve that determines how much water is allowed to enter the brine tank during regeneration. As received, the float is held in place with a rubber band to prevent rattling during shipment. This rubber band needs to be removed before use or else the tank will overflow with water.

Both the deionizer and water softener used push-in connectors design for 3/4" Pex tubing. My system was installed in a slide tray so that I could easily access the softener for service so hard plumbed Pex wasn't going to work for me. Instead I bought some stainless steel braided hoses with 3/4" female garden hose fittings designed for a clothes washer. These would give me the flexibility needed when sliding the tray out from the basement compartment in the coach. I bought a few 3/4" male GHT by make GHT adaptors so that I could convert one end of each hose to male garden hose thread so that I wouldn't get my ins and outs mixed up when I removed the unit during winter storage. I also picked up some threaded Pex adaptors so that I could adapt the stainless braided garden hoses to the plug-in connectors on the equipment. I cut four short 3/4" Pex stubs and used a crimp tool to crimp them on to the brass shank adaptors. I added some pipe thread by garden hose adaptors to finish the pieces. I slipped them into the valve bodies and hand tightened the retaining nuts.

The RoadWave pressure washer was already mounted in the cargo slide tray. It needed to be on the outside edge so that it could be easily accessed for use. The deionizer will rarely need to be accessed so the best choice would be to locate it in the back of the tray. The brine tank will need occasional access to add salt and the softeners control panel needs to be visible to allow programming changes or to initiate a forced regeneration cycle. These three items did eventually fit into the tray. I decided to cut some aluminum angle iron pieces which would be screwed to the plywood floor in the cargo tray to keep them in place so they wouldn't move around when traveling.

About 20-25 gallons of water is flushed through the softener during the backwash cycle portion of regeneration. This water is routed to the gray water tank. I ran a polyvinyl tubing from the push-in connector on the water softener valve to the gray water tank. I drilled a hole in the top of the ABS plastic gray water tank, threaded it with a pipe tap and inserted a brass hose barb connector to connect the other end of the hose to. Sealant was applied to the threads. The brine tank also had an overflow hose. This is just in case the float valve in the tank failed. I simply drilled a hole in the basement floor and ran the clear vinyl hose out through it so that any overflow would drain onto the ground. It would be clean water should that ever happen so I didn't see the need to have to run it into a holding tank.

Once everything was fastened in place, the brine tank was connected to the softener with the black nylon tubing that was supplied with the softener. The stainless steel braided garden hose lines were connected to input and output ports on the softener and deionizer valves. A small 120 volt power adaptor was plugged into a nearby basement electrical outlet fed by the inverter to supply power to the softener. The garden hoses, drain lines and power cord were all bundled together with black nylon cable ties and clamped at the rear of the slide tray with rubber hold-down clamps. This allowed everything inside the tray to remain stationary while giving enough flex between the tray and the plumbing connections in the next bay to allow the tray to easily be extended for service access. Finally, the brine tank was filled with solar salt and 5 quarts of water were added to the tank to allow it to make the initial brine.
