On The Go OTG4-VM-DBLSOFT Portable Double 16,000 Grain
The OTG4-VM-DBLSOFT is a compact, double-softener system offering 16,000 grains of capacity. It regenerates with standard salt and is designed for RV owners who need a larger buffer of soft water between regenerations. This model is best for frequent travelers or larger RVs where higher soft-water output is beneficial. It is assembled in Indiana for U.S. workers, which may appeal to buyers prioritizing American-made assembly. A caution: head-fitting changes for certain shower installations may require additional hardware not included in the base kit.
OTG4-DBLSOFT-Portable 16,000 Grain RV Softener
This Double Standard Softener is the largest compact RV softener on the market and provides up to 40% more soft water than many alternatives. It regenerates quickly—typically in under 30 minutes—and supports higher flow with minimal pressure drop. It’s well-suited for RVers who frequently run multiple water outlets (shower, sinks, and appliances) simultaneously. Best for larger RVs or travel groups where a steady supply of soft water matters. Caution: installation space must accommodate its double-standards design, and some installations may require additional fittings.
On The Go Portable 16,000 Grain Double Softener With Kit
This unit mirrors the 16,000-grain double-softener configuration and includes a salt regeneration kit and carbon filtration. It’s designed for RV/marine owners who want a turnkey solution that cleanly regenerates in under half an hour and delivers better-tasting water. Choose this if you need an all-in-one setup with additional filtration. Limitation: regeneration depends on salt availability and may require periodic salt replenishment at the tank’s capacity.
On The Go OTG4-StdSoft-Portable 8,000 Grain
The 8,000-grain standard softener is a lighter-weight option ideal for smaller RVs or occasional use. It is easy to carry, with a large mouth for salt addition and a quick regeneration cycle under 15 minutes. Best for solo travelers or couples with modest soft-water needs. Better for limited space but may require more frequent regenerations compared to higher-capacity units.
VEVOR RV Water Softener, 16,000 Grain
The VEVOR unit offers 16,000 grains of capacity with 3/4″ brass fittings and a 42″ hose. It emphasizes higher adsorption capacity, fast softening, and a robust pressure rating up to 150 psi. It is suitable for RVs, trailers, boats, and mobile service setups requiring reliable soft water with decent flow. Caution: ongoing maintenance includes resin regeneration and periodic salt replenishment, and some buyers may prefer units with more explicit installation instructions.
Buying Guide
What grain capacity do I need for RV use?
Grain capacity indicates how much hardness the unit can remove before regenerating. RVs with high daily water use (showers, laundry, multiple taps) benefit from 16,000 grains or more. Smaller units (8,000 grains) are suitable for light usage or smaller RVs and may regenerate more often.
Is a double-softener model worth it?
Double-softener designs provide more soft water per regeneration and can be advantageous for families or travel groups. They often regenerate faster and support higher flow, but they take more space. Choose this if you consistently run multiple water outlets simultaneously.
What installation considerations matter?
Look for compact dimensions, ease of regeneration, and the availability of replacement salt. Units with simple fittings and clear manuals reduce on-the-road setup time. Note any required additional fittings for showers or specific RV configurations.
How important is “Made in USA” assembly?
Some buyers prefer U.S.-assembled units due to perceived quality controls. If this matters, prioritize models marketed as assembled by U.S. workers, while verifying current product details and compatibility with your RV plumbing.
What about filtration or additional kit items?
Some packages include carbon filters or regeneration kits. These extras can improve taste and odor but add to cost. Consider whether you need an all-in-one solution or a straightforward softener with separate filtration.
Maintenance and replacement parts
Resin life, salt usage, and the availability of replacement parts influence long-term costs and downtime. Favor units with readily available salt, resin, and parts in your region and clear maintenance guidance.
FAQ
- Q: How often will I need to regenerate a 16,000 grain RV softener?
A: Regeneration frequency depends on water hardness and usage. In typical RV scenarios, a 16,000 grain unit can last days to weeks between regenerations, with cycles lasting around 15-30 minutes in many models. - Q: Can I install these in a standard RV storage compartment?
A: Most compact models fit standard RV storage spaces, but verify dimensions and clearance for hoses and fittings before purchase. - Q: Do these units affect water pressure?
A: They are designed to minimize pressure drop, but some units may slightly reduce flow under heavy use. Look for models with high flow and low pressure drop specifications. - Q: Are these units good for drinking water?
A: Some models include components that improve taste and odor, and all listed units treat hardness. If you require additional water purification, consider a separate carbon filter or a dedicated drinking-water kit. - Q: Do these come with installation accessories?
