Best Marine Water Softener Buyer’s Guide
When thinking about buying a marine water softener for your boat, you should be aware of several key factors. These include the size of the unit, the regeneration time, the grains or capacity, and the maintenance & warranty of the softener.
The size is very important as you are going to be taking this portable water softener with you on your boat. Just like RV’s, boats have only a limited amount of space, which must be used wisely. You also don’t want something that is large and awkward to try to get on and off the boat at the docks. Because of this, you need to pay attention to the size.
Typically, a home water softener takes between 85-90 minutes to its complete regeneration cycle. Regeneration is when the water softener cleans and softens the water via a medium and chemical reaction that removes the unwanted and dissolved minerals from the water.
Marine water softeners are much smaller, so the regeneration time is much less. Typically between 30-45 minutes. This is great as it means that you will have less time to wait, should you be waiting for soft water to take a shower or wash some dishes.
The way to determine what grains you will need is how much salt it will use to the cubic feet of resin. Grains is one the more confusing part of purchasing a water softener but manufacturers do usually put the output of the softener out there for you.
How much salt is used and how often the regeneration process needs to be will tell you the efficiency of that machine. Typically, the harder your water and/or the more water you use, the higher the grain capacity you should get. You can check out this guide to get a better understanding of water softener grain capacity.
Maintenance & Warranty
Luckily, water softeners tend to be very low maintenance products. Most of them you can simply set them and let them run automatically. That being said, there is minor maintenance to be done, such as adding salt and changing filters.
The warranty should also be considered, as you want to know that your softener is protected, should there ever be an issue.
While many campers and boaters love their Marine Water Softener, it can also be used in a home as a backup water softener. Not only are you saving your pipes with soft water, but you can also know that you are washing clean water as well. This is a great investment for anyone that loves camping and boating and is a great investment for saving your pipes.
They operate the same way that your home water purification system works through ion exchange. Most of the time they arrive ready to go. However, you might need to add salt and allow it to go through the regeneration cycles before using it. This will depend on the model.
The best marine water softeners come with hose connectors, however, you should keep some Teflon tape handy to prevent leaking. Most connect directly to a hose without the need for tools.
We hope that our reviews have made it easy for you to purchase your new boat water softener.
