Kent Grand Plus RO Water Purifier

How Much Is a Used Kent Grand Plus RO Water Purifier Worth in India?

A used Kent Grand Plus RO Water Purifier is worth ₹4,500 to ₹15,000 in India in 2026, depending on its physical condition, age, and maintenance history. This range reflects everything from a well-maintained, recently serviced unit to one that’s several years old and needs immediate filter replacements. The closer it is to “like new” condition, with fresh filters and a working membrane, the higher its value.

Is the Kent Grand Plus RO Water Purifier Still Worth It in 2026?

Absolutely, the Kent Grand Plus RO Water Purifier remains a solid choice in 2026, especially for the used market. This model, likely launched around 2019-2020, means even the newest second-hand units are 6-7 years old. However, Kent has built a strong reputation for reliable RO purification, and the Grand Plus is a testament to that. Its core technology – RO+UV+UF with a TDS controller – is still highly effective for tackling India’s diverse water quality challenges.

The real-world usability hasn’t diminished. Kent maintains a vast service network across India, making spare parts and qualified technicians readily available. You won’t struggle to find someone to service it, unlike some niche brands. This strong service ecosystem is a major advantage for any used appliance.

Bottom line: If you’re looking for dependable water purification without the upfront cost of a new high-end unit, a well-maintained used Kent Grand Plus is definitely worth considering. Just factor in the immediate maintenance costs.

Kent Grand Plus RO Water Purifier Price Guide

Note: As the Kent Grand Plus is a single model, significant variant adjustments (like storage capacity) are usually not a factor here. Use the calculator below for a personalized estimate based on your exact specs.

Advantages — Why Buyers Pick the Kent Grand Plus RO Water Purifier in 2026

Proven Multi-Stage Purification: The Kent Grand Plus offers a robust RO+UV+UF+TDS Controller purification process. This combination effectively tackles bacteria, viruses, dissolved impurities, and suspended solids, making the water safe and palatable across most Indian water conditions. It’s a comprehensive solution for household water safety.

Reliable Brand & Extensive Service Network: Kent is a household name in India for water purifiers. This means you get a product from a trusted brand with a widespread service network. Finding genuine spare parts and qualified technicians for maintenance or repairs is rarely an issue, even in smaller cities.

TDS Controller for Taste and Health: A standout feature is the built-in TDS controller. This allows you to adjust the level of essential minerals in the purified water, ensuring it tastes good while retaining vital nutrients. Many cheaper purifiers simply strip all minerals, which isn’t ideal for long-term health.

Good Storage Capacity: With an 8-litre storage tank, the Grand Plus provides ample purified water for an average Indian family throughout the day. You won’t constantly be waiting for the tank to refill, which is a significant convenience during peak usage hours.

Zero Water Wastage Technology (Newer Units): Later iterations of the Kent Grand Plus incorporated Zero Water Wastage Technology. This ingenious system recirculates the rejected water back to the overhead tank, minimizing water wastage during the RO process—a big plus in water-scarce regions. If you find a unit with this, it’s a major advantage.

Durable Construction: Kent purifiers are generally built to last. The Grand Plus features food-grade plastic construction, which is robust and safe for storing drinking water. Many owners report these units running reliably for years with proper maintenance.

Disadvantages — Why You Might Skip the Kent Grand Plus RO Water Purifier in 2026

Water Wastage (Older Units): While newer models feature Zero Water Wastage, many older Kent Grand Plus units do not. The RO process inherently generates a significant amount of reject water—sometimes up to 70-80% of the input water. If you’re water-conscious and don’t have a system to reuse this reject water, it can be a concern.

Higher Running Costs: As an RO purifier, the Kent Grand Plus requires regular filter and membrane replacements. These components are essential for purification but add up to a notable annual maintenance cost. If your budget is extremely tight for ongoing expenses, this might be a factor.

Can Be Noisy: The high-pressure pump inside the RO purifier can generate a noticeable humming or buzzing sound during operation. While not excessively loud, some users find it intrusive, especially if the purifier is installed in a quiet kitchen or close to living areas.

Bulky Design: The Kent Grand Plus is a fairly substantial appliance. It takes up considerable wall space or counter space if placed on a tabletop. If your kitchen is compact or you prefer a sleeker, more integrated look, its size might be a disadvantage.

No Smart Features: This model is from an era before smart home integration became common for appliances. It lacks features like app connectivity, filter change reminders via mobile, or real-time water quality monitoring, which are found in some newer purification systems.

Tank Cleaning Required: Like all storage-based water purifiers, the internal tank of the Kent Grand Plus needs periodic cleaning to prevent slime or algae buildup. While not difficult, it’s an additional maintenance step many users overlook, potentially leading to hygiene issues.

Factors That Affect Kent Grand Plus RO Water Purifier Resale Value

Age of the Unit: This is huge. A 2-year-old unit will fetch significantly more than a 6-year-old one. Expect a ₹1,500-2,500 drop in value for every additional year of age beyond 3 years.

Condition of Filters and RO Membrane: This is the single biggest determinant of value. If the RO membrane is new, that’s an instant ₹2,000-4,000 bonus. Fresh sediment and carbon filters add another ₹800-1,500. If all filters are due for replacement, expect buyers to deduct ₹3,000-5,000 from your asking price.

Physical Condition (Cosmetics): Minor scratches or slight discoloration are acceptable, but major dents, cracks in the casing, or significant fading can reduce the value by ₹1,000-2,500. A pristine exterior makes a big difference.

Service History and Records: Having original purchase bills, warranty cards (even if expired), and AMC service records adds immense credibility. Buyers will pay ₹500-1,000 more for verifiable maintenance history.

Working Condition of Components: Ensure the high-pressure pump runs smoothly, the UV lamp is functional (if applicable), and the TDS controller is operating correctly. Any non-working component can reduce value by ₹1,500-4,000 depending on the part.

Original Accessories: If you have the original installation kit, user manual, and the tap for purified water, it helps. Missing these might lead to a ₹200-500 deduction.

Location and Water Quality: In areas with extremely hard water, buyers might be warier of older RO units, expecting more wear. In metro cities with higher demand, prices might be slightly firmer.

Known Issues — Reported by Real Kent Grand Plus RO Water Purifier Owners

Frequent Filter Clogging in High TDS Areas. Many owners in areas with high sediment or very hard water, as reported on Reddit r/HomeImprovementIndia and local Quora threads, find the sediment and carbon filters clog much faster than the advertised 6-12 months. This leads to reduced water flow and more frequent replacement costs.

RO Membrane Failure or Reduced Efficiency. Forums often discuss RO membranes failing prematurely or showing reduced water output and higher TDS readings after 1.5-2 years, rather than the expected 3 years. This can be due to scale buildup from hard water, necessitating earlier and costly membrane replacements.

Pump Noise and Vibration Issues. Some users on JustDial reviews and support forums have noted that the high-pressure pump can become excessively noisy or develop vibrations after a few years of use. This often indicates wear and tear on the pump motor or mounting, potentially leading to pump replacement.

Leakage from Joints and Fittings. Over time, the plastic tubing and push-fit connectors can degrade or loosen, leading to minor leaks around the purifier. This is a common complaint, requiring careful inspection and tightening or replacement of fittings by a technician.

TDS Controller Inaccuracy. While a great feature, some owners report that the TDS controller can become less accurate over time, leading to inconsistent mineral levels in the output water. This requires recalibration or replacement of the TDS controller unit.

UV Lamp Indicator Malfunctions. Occasionally, the UV lamp indicator might show an error or the lamp might stop working, even if it hasn’t completed its full lifespan. This necessitates checking the lamp and potentially the ballast or power supply, as noted in various manufacturer support forums.

Warranty Status Timeline

For a Kent Grand Plus RO Purifier of this age, third-party insurance from providers like Flipkart or Amazon is generally not worth the premium. The cost of typical repairs would likely outweigh the policy benefits, and many policies have age restrictions.

Pre-Purchase Inspection Checklist

Essential Checks

1. Check Output Water TDS: Ask the seller to run the purifier and use a TDS meter to check the output water. It should be within a reasonable range (e.g., 50-150 ppm, adjustable with the TDS controller). This immediately tells you about the RO membrane’s health.
2. Inspect for Leaks: Look carefully under and around the unit for any water stains, drips, or signs of past leakage. Pay attention to joints, the tap, and the housing.
3. Listen to the Pump Noise: Let the purifier run for 5-10 minutes. The high-pressure pump should hum smoothly, not rattle, click, or vibrate excessively.
4. Examine External Casing: Check for any major cracks, dents, or deep scratches on the plastic body. These can indicate rough handling or impact damage.
5. Verify Manufacturing Date: Find the sticker or label, usually on the back or side, that states the manufacturing date. This gives you the true age of the components, not just the purchase date.
6. Check Power Cord Condition: Ensure the power cord is free from cuts, fraying, or burn marks, especially near the plug pins.
7. Confirm Water Flow Rate: Observe the flow rate from the purified water tap. It should be a steady stream, not a trickle, indicating good filter and membrane health.
8. Verify UV Lamp Indicator: If the unit has a visible UV indicator, ensure it’s glowing when the purifier is running, confirming the UV lamp is active.
9. Inspect Storage Tank: Politely ask to open the storage tank (if accessible) and inspect it for cleanliness. There should be no slime, algae, or foul smell inside.
10. Ask for Filter Change History: Inquire about when the sediment, carbon, and RO membrane filters were last changed. This impacts immediate running costs.

Insider Checks

THE OUTPUT TDS TEST: Don’t just trust the seller’s word on water quality. Bring your own portable TDS meter (you can buy one for ₹300-500 online). Run the purifier for a few minutes, then check the TDS of the output water. If it’s above 150-200 ppm even with the TDS controller adjusted, the RO membrane is likely worn out. Missing this can cost you ₹2,500-4,500 for a new membrane right away.

THE PUMP HUM TEST: Listen closely to the heart of the purifier. While the unit is running, place your hand gently on the side where the pump is located. You should feel a smooth, consistent vibration and hear a steady hum. Any loud rattling, grinding, or intermittent clicking suggests the pump is failing or worn out. A new pump can set you back ₹2,000-4,000.

THE LEAKAGE SPOT CHECK: Look for the hidden tell-tale signs. Even if the unit looks dry, check for water marks or rust stains on the surface it sits on, or inside the cabinet if wall-mounted. These often indicate intermittent or slow leaks that the seller might have wiped away. Missed leaks can lead to water damage or continuous small drips, costing ₹500-1,500 for new fittings and plumber visits.

THE TANK SMELL TEST: Your nose knows best about hygiene. Open the purified water tap and let some water out. Then, if possible, open the storage tank lid (some models allow this, others don’t easily) and take a sniff. A musty, stale, or moldy smell means the tank hasn’t been cleaned regularly and might have bacterial buildup. Cleaning takes effort, or a service visit for ₹300-500.

THE MANUFACTURING DATE TRICK: Don’t get fooled by “recently bought.” Always check the manufacturing date printed on the rating label. Sellers often say “I bought it 2 years ago,” but the unit might have been manufactured 1-2 years before that. The manufacturing date tells you the actual age of its internal components. An extra year or two of age means filters and the membrane might degrade faster, costing you ₹1,000-2,000 sooner than expected.

THE FILTER HOUSING CRACK TEST: Inspect the clear parts. If the Grand Plus has clear pre-filter housings, inspect them for hairline cracks, especially near the top or bottom connections. These are common stress points and can lead to slow, persistent leaks that are hard to spot until they become significant. Repair can range from ₹300 for a gasket to ₹1,000-1,500 for a new housing.

Common Scams to Watch For (India 2026)

Fake Filters and Membranes: A common scam is when a seller claims “new filters installed” but has used cheap, generic, or even counterfeit filters and RO membranes. These don’t last as long or purify as effectively. Always ask for the bill for the new filters, or visually inspect them for brand markings. If in doubt, assume you need to replace them, costing you ₹3,000-5,000.

“Just Serviced” Lie: The seller might claim the unit was just serviced, but this could mean a quick external wipe-down and nothing more. Ask for a service report or bill. Without proof, assume it needs a full service and filter change, which will be an immediate expense for you.

Hidden Leaks: A seller might temporarily fix a leak with sealant or by tightening a loose fitting just before your visit. Run the unit for 15-20 minutes during inspection, and check for any fresh drips or moisture. Small leaks often reappear after continuous use, leading to repeated service calls.

Misleading TDS Readings: Some unscrupulous sellers might use a faulty TDS meter that consistently shows low readings, or even pre-purified water to demonstrate low TDS output. Always use your own TDS meter (as per the Insider Check) to get an accurate reading.

Refurbished Parts as “New”: If a major component like the pump or UV lamp has been replaced, a seller might claim it’s “brand new” when it’s actually a refurbished part from a scrap unit. Ask for the service bill for the replacement. Refurbished parts often have a much shorter lifespan.

Inflated Purchase Price Claims: Sellers often inflate the original purchase price to justify a higher resale value. While the original price was ₹20,000, remember this was years ago. Focus on the current market value based on condition and age, not what they paid for it.

Seller’s Guide — How to Maximize Your Kent Grand Plus RO Water Purifier Resale

Physical Preparation

Thorough Cleaning: This is non-negotiable. Wipe down the entire exterior with a damp cloth, removing dust, grease, and water stains. If possible and safe, open the storage tank and clean it thoroughly with a mild disinfectant. A clean unit instantly builds buyer trust.

Run a Cleaning Cycle: If your unit has a tank cleaning mode, run it. Otherwise, run an empty cycle to flush out any stagnant water and ensure the internal components are fresh.

Minor Fixes: Tighten any loose screws, wipe down the power cord, and ensure the tap isn’t dripping. Small details make a big difference in perceived value.

Functionality & Documentation

Verify Working Condition: Run the purifier for 10-15 minutes before showing it. Ensure the pump runs, the UV indicator lights up, and water is dispensed. Take a short 30-second video of it working, showing the purified water flowing and any indicator lights. This is a powerful selling tool for online listings.

Check TDS Output: Use a TDS meter to measure the output water. If your RO membrane is still good, a low TDS reading (e.g., 50-150 ppm) is a major selling point. Be ready to share this reading with potential buyers.

Gather Documents: Collect the original purchase bill (even if expired warranty), the user manual, and any service records or AMC bills. These add significant credibility and can increase your resale value by ₹500-1,000.

Listing & Photography

Clear, Well-Lit Photos: Take multiple photos from different angles. Include a clear shot of the entire unit, close-ups of the model number sticker (usually on the back/side), the purified water tap, and any indicator lights that are on when working. Good lighting is key.

Highlight Key Features: In your listing description, mention the multi-stage purification (RO+UV+UF+TDS Controller), the storage capacity (8L), and if applicable, the Zero Water Wastage Technology.

Be Transparent: Disclose any minor cosmetic flaws or known issues upfront. Honesty builds trust and reduces negotiation friction later.

Platform Choice

List your Kent Grand Plus RO Water Purifier on platforms like Bids44.com to allow buyers to compete for your unit, potentially getting you a higher price. Also consider local classifieds like OLX or Facebook Marketplace for direct local buyers. For quicker sale, local appliance dealers might offer a lower but immediate cash price.

Final Verdict — Should You Buy or Sell in 2026?

For buyers: If you’re on a budget and need reliable, effective water purification, a used Kent Grand Plus RO Water Purifier is a smart choice in 2026. It offers proven technology and a strong service network, making it a dependable appliance for years to come. Look for units that have had their RO membrane and filters replaced recently, or be prepared to factor in those costs immediately. Aim to buy a unit in “Good” condition for ₹7,500-10,000 to strike a balance between cost and remaining lifespan. If your budget stretches further, consider a newer Kent model like the Kent Grand Z or Kent Supreme Lite for modern features and a fresh warranty.

For sellers: Your Kent Grand Plus still holds decent value, but its age means buyers will be focused on its maintenance history and the condition of its filters. Be realistic with your pricing; a unit in “Good” condition should fetch ₹7,500-10,000, with negotiation room. Thoroughly clean your unit, gather all service records, and take clear photos to attract serious buyers. Listing on platforms like Bids44.com can help you reach a wider audience and secure a competitive price for your well-maintained purifier.
