Watts Premier RO Pure Plus VOC 4-Stage Reverse Osmosis System

1. Introduction

The Watts Premier RO Pure Plus VOC 4-Stage Reverse Osmosis System is designed to provide clean, great-tasting drinking water by effectively reducing various impurities. This compact unit fits conveniently under most counter spaces and features a user-friendly design for installation and maintenance.

The system utilizes a multi-stage filtration process to ensure high-quality water:

• Stage 1: 5-Micron Sediment Filter - Reduces dirt, silt, and rust particles.
• Stage 2: 5-Micron Carbon Block Filter - Reduces chlorine taste and odors.
• Stage 3: 50 GPD Membrane - Reduces dissolved solids and contaminants such as chromium, arsenic, copper, lead, cysts (Giardia, Cryptosporidium).
• Stage 4: VOC Carbon Block Final Polishing Filter - Removes Volatile Organic Compounds (VOCs) including MTBEs, Atrazine, Benzene, Chloroform, Lindane, and Xylenes.

This image illustrates the four distinct filtration stages of the RO Pure Plus system, detailing the function of each filter in purifying water.

2. System Components

The Watts Premier RO Pure Plus system includes the following main components:

• RO Pure Plus Module with pre-installed filters (Sediment, Carbon Block, RO Membrane, VOC Filter)
• 3-Gallon Metal Storage Tank
• Brushed Nickel Top-Mount Twist Air-Gap Faucet
• Parts Bag (containing tubing, fittings, drain saddle, adapt-a-valve, etc.)

This image displays all the components included with the Watts Premier RO Pure Plus system, such as the filter module, storage tank, faucet, and various installation parts.

3. Setup and Installation

This system is designed for under-sink installation and operates using water pressure. While installation is generally straightforward, it is recommended to consult the full installation instructions provided with the product. Basic plumbing knowledge is beneficial.

3.1. Installation Overview

The system connects to your cold water supply, with filtered water dispensed through the dedicated faucet and wastewater directed to the drain. Ensure adequate space under your sink for the filtration module (approximately 15"L x 14"W x 15"H) and the storage tank.

This diagram illustrates the complete plumbing connections for the RO system, showing how the cold water supply, filter module, storage tank, faucet, and drain saddle are interconnected.

3.2. Drain Saddle Installation

Proper drain saddle installation is crucial for preventing leaks and ensuring efficient wastewater disposal. The black drain line must have a downward slope from the faucet to the drain saddle. It should not drop below the drain saddle connection point.

This image provides visual guidance on the correct installation of the drain saddle, emphasizing the necessary downward slope of the drain line to prevent issues.

3.3. Post-Installation Flushing

After installation, it is essential to flush the system thoroughly before consuming water. This process removes air and any manufacturing residues. Fill the holding tank completely, then drain it entirely. Repeat this process a minimum of four times over a 24-hour period. This ensures optimal water quality and prevents a "plastic" taste.

3.4. Leak Check

After turning on the water supply, carefully check all connections for leaks. Continue to monitor for leaks regularly for the first few days after installation.

4. Operation

The Watts Premier RO Pure Plus system operates automatically using your home's water pressure. Once installed and flushed, the system will fill the storage tank with purified water. To dispense water, simply open the dedicated RO faucet. The system will automatically refill the tank as water is used.

A slight gurgling or trickling sound from the drain line during filtration is normal. This indicates that the system is discharging concentrated wastewater, a standard part of the reverse osmosis process.

5. Maintenance and Filter Replacement

Regular filter replacement is crucial for maintaining optimal system performance and water quality. Filter life can vary based on local water conditions and usage patterns.

5.1. Recommended Filter Replacement Schedule

• Sediment and Carbon Pre-filters (Red and Yellow): Every 6 months
• VOC Filter (Gray): Once a year
• RO Membrane (Green): Every 2 to 5 years

The system's faucet may include an indicator light that changes color to signal when filter replacement is due. Additionally, a significant drop in water production or a change in water taste can indicate that filters need replacement.

This image provides a step-by-step guide for replacing the quick-change filters: press the button, pull the old filter, insert the new filter, and push to secure.

5.2. Filter Replacement Procedure

The pre-installed filters feature a quick push-button release mechanism for hassle-free replacement without special tools:

1. Turn off the water supply to the RO system.
2. Press the release button on top of the filter housing.
3. Twist and pull the old filter cartridge downwards to remove it.
4. Insert the new filter cartridge, aligning it with the housing, and push it upwards until it clicks into place.
5. Turn on the water supply and check for leaks.

5.3. Compatible Filter Kits

Ensure you use genuine Watts Premier replacement filters for optimal performance and to maintain your warranty.

This image shows different filter kits designed for the RO Pure Plus system, such as the Bi-Annual Filter Kit (531102), Annual Filter Kit (531109), and multi-pack options (531160, 531161).

6. Troubleshooting

This section addresses common issues you might encounter with your RO Pure Plus system.

6.1. Low Water Production or Slow Flow

• Clogged Filters: Sediment and carbon pre-filters can become clogged, especially with heavy use or poor water quality. Replace them according to the recommended schedule or if flow significantly decreases.
• Low Water Pressure: The system requires adequate incoming water pressure (minimum 40 PSI, maximum 80 PSI). Check your household water pressure.
• Depleted RO Membrane: The RO membrane can become fouled over time. If pre-filters are new and pressure is good, the membrane may need replacement (typically every 2-5 years). A TDS (Total Dissolved Solids) meter can help determine membrane efficiency; replace if TDS readings are consistently above 010 PPM.
• Air in Storage Tank: Ensure the air pressure in the storage tank is correct (usually 5-7 PSI when empty).

6.2. Leaks

• Loose Connections: Ensure all tubing is fully inserted into quick-connect fittings. Push firmly until seated.
• Air-Gap Faucet Leaks: Leaks from the air-gap vent on the faucet are often caused by improper drain line installation.

This image highlights the RO faucet air gap and lists common reasons for leaks, primarily related to incorrect drainage setup.

Common causes for air-gap faucet leaks include:

• Drain tubing is sagging or kinked, preventing proper drainage.
• Drain saddle connection point is not aligned with the hole drilled in the tailpiece.
• Drainage tailpiece hole is too small (should be 1/4 inch diameter).
• Drain saddle installed too close to a garbage disposal, causing debris to plug the drain opening.
• Standing water in the p-trap, indicating a blockage in the drainage system or vent piping.

6.3. Unusual Taste or Odor

• Incomplete Flushing: Ensure the system was flushed adequately after installation or filter changes (refer to Section 3.3).
• Expired Carbon Filters: Carbon filters have a limited capacity to absorb chlorine and VOCs. Replace them as recommended.
