Buyer’s Guide

Knowing the features to look out for when shopping for a new reverse osmosis system for your garden will save you from ending up with a product that you will regret buying. 

When shopping for a reverse osmosis system, you want to look out for 

  • Amount of Water Used 

The amount of water that gets wasted is one of the things you want to consider in your water purification system. In commercial hydroponic systems where seawater is used, you will need a large amount of water to reduce the salt that gets into the grow bed.

Newer models of the reverse osmosis system make use of a little amount of water, thus saving you the extra cost on the water bill at the end of the month. 

  • pH Level of the Unit 

The pH level is also one feature you want to look out for when shopping for a reverse osmosis system. Most reverse osmosis systems work by reducing the pH level of the incoming water; this means that they can work with water from any source. 

The reduction in the pH levels of the water changes its taste. While it is safe to drink, you might want to use a remineralization unit to add minerals to the water that can influence its taste. 

  • Installation of the Unit

You also want to consider if the unit is easy to install. Most of the home units can be put together by following the manufacturers manual, so you may not need the services of a professional. You want to make sure that you will not be making additional expenses since the best units are usually on the high side. Before leaving the store or completing your online purchase, you should check that all the equipment for installation is in the unit.

  • Purification Stages 

You also need to take into consideration the different stages of purification. Most units are designed to provide up to seven purification stages. The number of purification stages doesn’t necessarily affect the quality of water. So you should be okay with a product that offers at least five stages of purification.  

  • Amount of Sediments 

The TDS or Total Dissolved Solid measures the number of sediments contained in drinking water. The common sediments include organic minerals such as chlorides, sulfates, magnesium, and potassium. A good reverse osmosis system should be able to remove more than 90% of sediments from your water. 

Reverse Osmosis for Hydroponics FAQs 

  • How Does Reverse Osmosis System Work? 

The working principle of water filtration systems differs depending on the design. Most reverse osmosis systems are designed with extremely tiny pores for the passage of water only. The filtration is made possible with the help of the membrane that helps to keep out the sediments and impurities. 

  • Do You Need a Reverse Osmosis System for Your Drinking Water? 

The truth is that there is nothing wrong with drinking tap water, especially if it is from a clean source. The decision is left to you since there are many cheaper options for a water purification system. A tabletop water filter can be used to improve the quality of water in the home. A reverse osmosis system will be a better addition if you have an indoor water garden. This way, you and your plants never run out of clean water. 

  • Is Reverse Osmosis Water Safe to Drink? 

Yes, the unit functions as a water filtration system that improves the quality of water. Although the water may be missing some minerals, it doesn’t in any way pose a threat to your health. 

  • How Often Should I Maintain My System 

RO systems are easy to use and require minimum maintenance.  Regular maintenance will need to be done every six months and usually involves changing the water filter or membrane. You don’t need to hire a maintenance expert, you can get the job done yourself without stress.

Which is better reverse osmosis or water softener?

The better option between reverse osmosis system and water softener will depend on your needs. Reverse osmosis will filter your water as well as soften it a little. In fact, reverse osmosis is one eco-friendly filtering system that does not make use of chemicals. 

On the other hand, a water softener will reduce water hardness. When your water is hard, there is a high presence of magnesium and calcium ions. This can cause dry skin and hair, faded laundry, water spots on glasses, and clogged pipes. A water softener will replace calcium and magnesium with sodium ions through the means of ionization. 

Therefore, reverse osmosis will be beneficial to you if your water needs filtering, while a water softener will favor you if your water suffers from water hardness.

Basically, they cannot be replaced by each other. Reverse osmosis system and water softener are simply significant combinations if you want extraordinary water. 

Can I use reverse osmosis water instead of distilled?

You can use a reverse osmosis water system instead of distilled water. The reverse osmosis system filters water through membranes and reverses osmosis water is free of chemical. 

Both reverse osmosis systems and distilled water are used to filter water and provide clean water for drinking. However, only a reverse osmosis system is ideal for residential purposes. 

Distilled water is a procedure of boiling water and condensing back to the water. Distilled water is also a way of purifying water. It is even purer than tap water although people don’t really enjoy drinking distilled water because it has been dematerialized. 

Also, distillation will not take away volatile chemicals as a reverse osmosis system would. So generally, reverse osmosis water is better than distilled water. 

Can I install a reverse osmosis system myself?

You sure can install a reverse osmosis system yourself if you are skillful and have a little mechanical idea. Installing a reverse osmosis system yourself isn’t so difficult or time-consuming. 

However, it’s usually better to trust a professional who has adequate knowledge and experience. If you are not so skillful or have a little idea of mechanical knowledge, you should allow a residential water treatment professional to install it for you. 

A professional will take into account factors such as your home’s water pressure, overall water quality, temperature, as well as the intervals the holding tank to the faucet. All this information is essential for better comprehension of the maintenance needs of your units. 

Do you need a reverse osmosis system with a water softener?

You will need a reverse osmosis system with a water softener because they work hand in hand and are both great combinations for remarkable water. 

A water softener will soften your water. On the other hand, the reverse system will filter the water. Making use of just a water softener isn’t ideal because impurities will still be in your water. Also, making use of only a reverse osmosis system will just enhance your hard water a little. Therefore, having the combination of a reverse osmosis system and water softener is ideal.
