Why Trust Water Softener Solutions?

Unlike many others in the industry, Water Softener Solutions is geared to ensuring that you select the best water softener for your needs. We’re versed in the industry and dedicated to providing the most compelling reviews that better equip you with everything you need to know before you make a decision. So if you’re looking for a new softener to better fuel your adventures, we’ve got you covered.

Why Should You Buy The OTG4-DBLSOFT Softener?

The 16000 Grain softener is not only compact and light but it’s easy to carry with an all-new swivel head that allows easy movement. The softener also has a relatively large opening so that you can easily pour salt into it. Due to the sleek new design, there are both outlet and inlet storage caps, a shutoff valve for hi-flow, test strips, a perfectly new stabilized cradle base, and a drinking hose.

Unlike others of similar designs, you’ll now be able to enjoy up to 40 days of softened water during cycles. However, this is still dependent on the volume used and the initial hardness of the water which significantly alter the lifespan of both fittings and appliances. With that said, this can easily be combated by simply preventing scale build-up with the softener as it improves the initial taste of your water. It also improves the quality of your lather during showers and washing.

If you’re planning to spend a lot of time at RV parks, you should already know that the compounds usually provide hard water. With this On The Go softener, you’ll be able to finally protect your RV’s water system and if you’re planning to resell at some point, you’ll get a good price since everything will be in tip-top shape. However, if you’re still skeptical, you should find some comfort in the fact that the manufacturers have over a decade of experience in the industry and their team consists of leading executives from several top manufacturing industries.

With its simple setup procedure, you’ll have softened water in just 5 easy steps. The unit already comes precharged with salt and a specially designed softener medium that ensures that the unit lasts up to 8 years. Since the hose has a standardized connection, you would not need other tools to open the system or even connect and disconnect it. However, you’re required to perform backflushes at least every 3 months.

Travel-Friendly Plug And Cap With 360-Degree Swivel Head
The swivel head is one of the best features since it’s easier to connect or even disconnect without rotating the entire softener. This offers peace of mind during travel since the plug and cap is installed to prevent spillage.

Larger Mouth And Back-Flush
The mouth at the top of the softener ensures that salt can be easily refilled without any waste occurring and the inlet flow allows a proper rinse when the system needs to be regenerated. As a result, you’ll be able to enjoy better water quality and you’ll be able to soften more water. In the case where you need to reverse your connection, the back-flush will facilitate this.


As we conclude, we have just looked at this state-of-the-art RV water softener.
