Water does not touch the metal or plastic shell of the tank. It touches only the butyl bladder and spout (usually stainless steel or hard plastic) as it enters or leaves the tankA synthetic rubber, or Elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubberThis RO tank has been tested and certified by NSF International under NSF/ANSI Standard 58 for material and structural integrity.Best Regards **Q: How do you know it is time to change the filters?** A: @Climers got it right. Most of the other answers are not, in that they suggest you to change filters AFTER you have detected something wrong at the output. Well, by that time, your RO membrane is kaput - no good any more. RO membranes are very sensitive to chlorine; so you must change your 3 front-line filters (1 sediment and 2 carbon) before they start to leak chlorine to the membrane. Doing so will prolong your membrane's life for many years. I have had a system working perfectly after 8+ years of continuous service, just by changing the first 3 filters regularly (yearly). **Q: I just ordered the filter system, do you sell extra complete sets of the filters?** A: Yes, You can also get them at Walmart, Home Depot, Etc if you live where there is one. **Q: What is the dimension of the manifold?** A: 13" wide, 16" high, 6" deep. the tank if 12" in dia and 16" high ## Frequently Bought Together - Express Water RO5DX Reverse Osmosis Filtration NSF Certified 5 Stage RO System with Faucet and Tank – Under Sink Water Plus 4 Filters – 50 GPD, 14 x 17 x 5, White - Express Water – 3 Year Reverse Osmosis System Replacement Filter Set – 23 Water Filters with 50 GPD RO Membrane, Carbon GAC, ACB, PAC Filters, Sediment SED Filters – 10 inch Size --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/7828266-express-water-ro5dx-5-stage-under-sink-reverse-osmosis-system](https://www.desertcart.gr/products/7828266-express-water-ro5dx-5-stage-under-sink-reverse-osmosis-system) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-27*
