Frequently Asked Questions: How Long Do RO Systems Last?

The last thing you want when you’re planning a long voyage at sea is to have to come ashore before planned. You can deal with a lot while you’re on your boat, but one thing you certainly cannot “handle” is a lack of fresh water. This is why a reverse osmosis system is an essential part of your gear

Let’s discuss exactly what this is, as well as a few other common questions. How long do RO systems last? Which reverse osmosis machine should you buy?

What is a RO System?

In this case, “RO” stands for reverse osmosis. A reverse osmosis system works via membrane filtration technology. It forces water under pressure through the very tiny pores of a semi-permeable membrane. 

It is an advanced water purification method that was initially developed by the U.S. Navy to produce drinking water from seawater. RO systems were originally used by Navy submarine crews gone for long periods of time. Reverse osmosis machines run on water pressure, so no electricity is needed!

How Long Do RO Systems Last?

A RO water system will last virtually forever if you service it regularly and replace parts that wear out. This includes things like the storage tank and the faucet. 

You can expect the membrane lifespan to be about 2 to 5 years. However, this depends on the nature of the water that it’s processing. We recommend you change the RO membrane every 24 months, just to be on the safe side.

Signs You Need a New Membrane Filter

If you aren’t sure whether your reverse osmosis system is ready for new RO filters, these are the signs you should be on the lookout for:

#1 Your water tastes bad

#2 Water pressure is poor

#3 The system is constantly cycling

Remember, if the membrane filters aren’t clean themselves, then your system can’t do its job. A poor water filter system gives you poor water. When you’re out at sea with no other form of fresh water, this simply will not do. We recommend replacing the filters on your reverse osmosis machine system before you leave for a trip if:

  • You haven’t changed them in over 24 months.
  • if it will be over 24 months since a change during the duration of your trip.
