Home Reverse Osmosis System Maintenance: Tips for Optimal Performance

Countertop RO systems like the SpiroPure SP-RO500 from All Filters are compact and easy to set up with plug-and-play installation. They are commonly used in small homes, apartments, and places where a filtration system is needed without permanent installation. Here's how to maintain them:

1. Scheduled Filter Changes

Filters in most countertop RO systems need to be changed frequently because they are small. If you consume 3–4 gallons (10–15 liters) of water in your household daily, you will usually need to change the sediment, carbon, and post-filter every 6–12 months for effective reverse osmosis system maintenance.

The RO membrane usually lasts 12–24 months when it's installed in countertop units as a changeable cartridge. Its lifespan can be increased with routine maintenance and pre-filter replacement.

2. System Cleaning

The sealed, connected design of countertop RO units makes them easy to sanitize. Running a cleaning solution through the system, wiping outside vents or sensors, and occasionally flushing the internal pathways are how you maintain the hygiene of a reverse osmosis system. In general, sanitizing should take place at least once a year when you change the filters.

3. General Surface Inspection

Countertop RO units are easily accessible, making reverse osmosis system maintenance simple, as problems can be identified easily. For example, you might notice a tiny leak, unusual noises, or slower water flow from your dedicated RO faucet or if your system is a kitchen countertop unit. A simple monthly inspection can prevent small issues from becoming expensive long-term repairs.

Under-sink RO systems like the SpiroPure SP-RO-100MP-BK from All Filters offer high capacity, long-term reliability, and various customization options. However, they have more components than countertop RO systems and require a slightly different maintenance routine. Here's how to maintain them:

1. Plan When to Buy Replacement Filters

The reverse osmosis system maintenance schedule for under-sink filters is similar to countertop RO systems, but their larger parts tend to last longer. For example, an average home that uses 3–4 gallons (15–20 liters) of purified water each day might change the post-filter once a year and the sediment and carbon prefilters every 6–12 months.

Usually, the RO membrane needs to be changed every 2–3 years. You can also use a basic portable meter to check the total dissolved solids (TDS) once in a while. If the TDS starts to climb, it usually means the membrane is nearing the end of its lifespan.

All Filters has an automatic email reminder service so you never forget when to buy your next filter.

2. Check the Tank Pressure

This part of reverse osmosis system maintenance is like keeping the right air pressure in a tire—if it's too high or too low, performance suffers. The tank on traditional under sink ROs should be pressurized to 7–8 pounds per square inch (psi) when empty. This pressure level helps move clean water up to the faucet. Maintaining proper pressure in a reverse osmosis system involves checking the tank pressure every 6–12 months.

3. Sanitize the System

Compared to countertop RO systems, under-sink units require more extensive sanitization. Once a year, or during major filter changes, turn off the water supply and remove the filters. Clean the housings with warm, soapy water and a soft brush or sponge. Next, add a dedicated water treatment sanitizer product to the first stage of the housing (or a small amount of bleach diluted with water) and for effective reverse osmosis system maintenance allow it to circulate and sit throughout the system before flushing thoroughly and reinstalling the filters and membrane.

4. Leak and Component Inspection

Leaks tend to be more common with under-sink RO systems because they contain more fittings and joints. During a routine check, it's advisable to inspect the following:

• Tubing connections: Look for discoloration, dripping, or looseness
• O-rings: Check parts like o-rings for cracks, wear, or damage
• Filter housing: Look for cracks or warping
• Tank base: Check for moisture or corrosion
• Valve seals: Make sure valves are leak-free and working properly

5. Membrane and System Flushing

Some under-sink RO systems need to be manually flushed after a filter change or after the system has been inactive for a period of time. For example, you might need to run water through the system for a few minutes after changing the membrane until it runs clear. For optimal maintenance of your reverse osmosis system, always follow the manufacturer's instructions.

Filters in reverse osmosis systems can last months, so knowing how to maintain them effectively often involves setting reminders to ensure you replace them on time.

In addition, products like the SpiroPure SP-LD200 and SP-LD100 leak detectors for RO systems can be installed near your unit to monitor for leaks or excess moisture. This will help prevent water damage and alert you to potential issues before they affect your system.

At All Filters, we recommend maintaining your RO system to ensure it continues to function optimally and provide clean drinking water. Leaks, decreased water flow, and membrane issues can be avoided by regular filter changes, system sanitization, and routine inspections. Whether you use a countertop or under-sink RO unit, adhering to a regular reverse osmosis system maintenance schedule extends the lifespan of your system.
