But you can also opt to use some affordable devices that allow you to check the quality of your water. The following devices come with several features that you may want to be incorporated into your reverse osmosis system. You also have the option of getting these accessories for your system later.

Water Test Kits

You can also get a water test kit for the home or office. These kits allow you to test for the presence of pollutants in the water. These pollutants include bacteria, chlorine, copper, iron, nitrate or nitrites, and pesticides. It also checks the hardness and pH level of the water using the standards set by the EPA. The impurities in water depend on numerous factors, including the source of your water.

Among the popular option you can consider are the WaterSafe Well Water Test Kit – for Drinking Water in Home Tap and Well Water.

Water Quality TDS Meters

A TDS meter is a portable device used to provide an accurate reading of total dissolved liquids or TDS in the water you are drinking. This simple device measures organic and inorganic substances in the liquid. These substances can be in ionized, micro-granular, or molecular form. This device rests the conductivity of electricity in the water. It uses the result to estimate the level of TDS. To use the device, all you need to do is to dip it into a glass of water.

HM Digital TDS-EZ Water Quality TDS Tester

One of the best TDS meters in the market is the HM Digital TDS-EZ Water Quality TDS Tester. This TDS meter is among the most popular devices used in checking the impurity level of water. It is capable of compensating for water temperature. This makes it easy for users to get a reliable reading.

After installing the system, you should monitor the quality of the water so you will know when it is necessary to change the filter. Manufacturers normally include the average timelines when you should replace the filters. These timelines are based on ideal conditions. Due to this, there may be instances when it is not applicable to you. You have the option of installing a device into the system or constantly monitor water quality using a portable device. The TDS level in the water should go down if the system is functioning properly. It should be reduced by around 90 percent. But this figure will go up as time passes.

HM Digital DM-1 In-Line Dual TDS Monitor

Another device you may want to consider is the HM Digital DM-1 In-Line Dual TDS Monitor. This device can be installed under the sink and connected to the outgoing and incoming water lines. These two connections allow you to get an accurate reading by comparing the two simultaneously.

UV Water Filters

When you detect the presence of bacteria in your water, you may want to get a UV filter for your reverse osmosis system. Sometimes a RO system has a UV filters included, like the iSpring RCC7AK-UV Deluxe Under Sink 7-Stage Reverse Osmosis Drinking Water Filtration System

This normally happens when you source your water from a well. The best way to deal with this issue is to get a base system with its own UV filter to allow you to save money and make it easy to setup. But it is also possible for you to install a UV filter after the system is already set up.

Tools for improving your RO’s efficiency

Water Storage Tanks

A Large pressurized storage tank is another accessory you may want to consider getting for your reverse osmosis system. These storage tanks feature a rubber bladder when filtered water is stored. They also have a pressurized diaphragm to increase the water pressure on the water faucet. But the usable volume the tank can store water will be lower since the diaphragm will take up some of the space.

Many reverse osmosis systems feature a storage tank. They normally have a size of four gallons with 3.2 usable gallons. When the water tank is filled, you will have 3.2 gallons of usable filtered water coming out of your faucet. But if a good amount of water is used for cooking, maintaining an aquarium, and other activities, you will need more than 3.2 gallons of water.

The water tanks on this list can be installed under an average-sized kitchen sink. It will allow you to increase the volume of usable filtered water in your home. These storage tanks can be laid down or installed in a standing position.

1. APEC Water Systems TANK-14 14 Gallon Pre-pressurized Reverse Osmosis Water Storage Tank

This water storage tank is a widely-accepted option for users of reverse osmosis systems. It functions similarly as smaller tanks but offers ten usable gallons of filtered water. The remaining four gallons are used for its pressurized diaphragm.

2. iSpring 20 gallon tank with 14 gallon Storage Capacity Reserve Osmosis Water Storage Tank

For additional water storage, the 20-gallon water storage tank from iSpring can be a good option. While it lists 20 gallons, its usable storage is 14 gallons. Since this storage tank has a 3/8-inch hose connector, an adapter may be necessary since most systems have a 1/4-inch hose.

Shutoff Valves

An automatic shutoff valve automatically closes the valves when the pressure in the water tank reached 65 percent of the incoming line pressure. When it reaches this point, the water tank is already full. A system without this automatic shutoff valve will continuously send rinse water into the waste drain. This continues even when the water tank is full. In this situation, the filters will not be able to produce clean water. These devices are important to allow you to save water.

The ISPRING Reverse Osmosis Water Filter Automatic Shut-Off Valve Quick-Connect ASV #AAS2 received numerous high ratings. This is a simple device that is compatible with standard 1/4-inch tubing.

Permeate Pumps

There are several reverse osmosis systems featuring permeate pumps. These systems normally have higher ratings compared to systems without them. Permeate pumps are non-electric devices that increase water pressure as it goes into the system. Increasing water pressure allows the system to work faster and more efficient. It also reduces water wastage when cleaning its filter membrane.

When efficiency is increased and wastage reduced, it will result in considerable savings when homeowners source water from municipal or city providers and pay for every gallon. Permeate pumps are useful accessories for users of reverse osmosis systems who want to save water or want to increase the efficiency of their systems.

You have the option of installing the pump into the system. The gallons per day or GPD shows how fast water goes through the system in a day. It does not indicate the maximum volume of water your pump can handle.

This permeate pump is sometimes bundled with several reverse osmosis systems, including the Home Master TMHP HydroPerfection Undersink Reverse Osmosis Water Filter System. Many reviewers gave high ratings for this permeate pump. It can process up to 100 gallons of water per day.

The extra tubing will be necessary when the ice kit is not long enough to connect the system to the refrigerator. There may also be instances when you want to flush water into a rain barrel outside instead of letting it into the drain.
