Campground water can be dirty and hard, leaving scale in your RV lines and a bad taste at the tap. This water filter and softener combo gives you clean, safe water that tastes good to drink and protects your RV's water lines and appliances.
Anyone who has hooked up to the water at a campground knows what can come out of those lines - sediment, chlorine, even bacteria and viruses that slip through standard RV filters. The AR3 solves that with three stages of protection:
Hard water leaves behind mineral deposits that clog lines, corrode faucets, and shorten the life of your appliances. The portable softener in the AR3 Elite reduces hardness and scale buildup, protecting plumbing, fixtures, and water heaters so they last longer. The resin recharges with table salt and can be used as often as you need.
Water pressure isn't the same at every campsite. Some spigots surge past what your RV's plumbing was built to handle, and over time that strain can crack fittings or shorten the life of your appliances. This Blu Tech regulator gives you control at the source. It adjusts pressure across a full range from 0 to 160 PSI, so you're in control no matter what spigot you connect to. It ships preset at 45 PSI, which is right in the 40 to 60 PSI range most RV plumbing is built for. It also includes a dual-layer inlet screen to block sediment before it reaches your lines, helping keep your water safe to drink while protecting your RV's system from campground surprises.
Most campgrounds only give you one spigot, but you often need more than one line. The included stainless-steel splitter gives you three outlets: one for the filter system, one for a garden hose to rinse gear or fill a bucket, and one for other uses at the site. Each outlet even has its own shut off valve for independent control.
The system includes a 25' stainless steel hose to reach campground spigots and two 5' hoses to connect the system to your RV and to the water softener. The stainless braids prevent kinks and protect against abrasion, so the hoses stay flexible and route where you need them without blocking water flow.
Instead of a fixed install under the sink, you set it up the AR3 outside when you're ready to draw water. The built-in 12V pump connects to your RV's power supply and pulls from a tank, barrel, or campground spigot. The outlet hose runs to your RV's fresh-water inlet just like a standard hookup. When you're done, the 14-lb frame and 5" filters pack up small enough to store in a bay or cabinet until the next stop.
The delivery was on time and the system arrived in good state . I was able to install and have the system working in a short period of time.
Product was exactly as described. Quality is A1!
I can’t give a complete five star review because all I did was unpackaged everything and put it together. I have not actually used it. I will give another review and update when I actually use it in February of next year. Thank you so much and I hope all is well.
