Certified to NSF standards, it ensures clean water without taste or odor contamination. Designed to optimize pump cycles by maximizing drawdown, it saves energy and extends pump life. Its compact, durable design with a high gloss enamel finish makes it ideal for professional-grade water systems requiring reliable pressure management. ## Description Product Description The WaterWorker pre-charged tanks utilize a butyl composite diaphragm, which flexes up and down based on water level and air pressure, as the pump fills the tank with water the air above the diaphragm is compressed, increasing the pressure in the tank until the pump cut-off pressure is reached. When water is drawn from the tank, the pressure inside the tank decreases until the pressure switch starts the pump. The amount of usable water for every pump cycles is called drawdown. The greater drawn-down capacity you select, the less your pump cycles saving energy, money, and extending your pump life. Advantages over galvanized well tanks: Pre-charged tanks do not have water-logging problems like the galvanized tanks. The air and water are totally separated using a diaphragm. No external air controls needed. Pre-charged tanks have a much larger draw-down for the same physical size. Larger draw down reduces pump cycles and pump wear, i.e. at 30/50 PSIG range three times the draw-down for pre-charged tanks of the same physical size. Pre-charged Tanks completely empty during each pump cycle. Pre-charged Tanks are much smaller and easier to handle that galvanized well tanks. Pre-charged tanks with a 30/50 Pressure Switch would be one-third the size of a galvanized tank with the same drawdown. Deep Well Jet Pumps could use either a vertical tank or a horizontal tank, depending on space requirements and sizing. Submersible Pump applications would usually use vertical tanks, again based on proper sizing. Shallow Well Jet Pumps could use vertical or horizontal tanks, based on proper sizing. The rule of thumb in sizing is to count the number of fixtures in the home, i.e. sinks, showers, toilets, dishwasher, faucets, washing machines, outside faucets, etc. and multiply it by 3. Example: a house with 11 fixtures x 3 would be 33-Gallon tank. We would suggest our 44-Gallon tank, which is the next larger sized tank.

Review: Water tank - Work good for me, mounted right up. Would buy again. ## Features - Designed to meet the requirements of, and are listed by the National Sanitation Foundation (NSF) under ANSI/NSF Std 61 - The Butyl diaphragm has seamless construction and is designed to flex rather than stretch and crease like bladder tanks - The polypropylene liner for the water reservoir will not flake, chip, crack or peel and does not impart taste and odor to the water - Diaphragm, liner isolate water from contact with deep drawn steel domed shell - twice as strong as rolled steel shell of same thickness - A high gloss enamel finish protects tank from the elements - Pre-charged to 25psi: please refer to product manual for proper pre-charge setting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000WCBU3M | | Best Sellers Rank | #423,446 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #719 in Water Pump Accessories | | Brand | Water Worker | | Brand Name | Water Worker | | Capacity | 14 Gallons | | Color | Blue | | Customer Reviews | 4.4 out of 5 stars 103 Reviews | | Global Trade Identification Number | 00642031613127 | | Included Components | Water Worker - HT14HB | | Item Type Name | Water Worker - HT14HB | | Item Weight | 16 ounces | | Manufacturer | Waterworker | | Manufacturer Part Number | Water Worker - HT14HB | | Manufacturer Warranty Description | Warranty. | | Model Number | Water Worker - HT14HB | | Number of Packs | 1 | | Specification Met | ANSI/NSF | | UPC | 642031384270 642031613127 | | Unit Count | 1.0 Count | ## Images ![WaterWorker HT-14HB Water Worker Horizontal Pre-Charged Well Tank, 14 Gal, 1 in Mnpt, 100 Psi, Steel, Blue - Image 1](https://m.media-amazon.com/images/I/71GwPO3ZumL.jpg) ## Questions & Answers **Q: under the read cap is a black plastic plug, inside the water tank. Is that suppose to be removed?** A: That thing under the red cap that you call a plug is not a plug. Think about it! The tank is precharged with 25psi which is pushing the bladder so hard against the fitting end of the tank that it pushes the part of bladder covering the hole up into it some so it looks like a plug to you! I assure you that what your referring to is the bladder! Do not mess with anything under that red dust cap because you will ruin the the whole thing if you do. **Q: on the back end of this tank - what is the opening size** A: As of this date (Feb 2020), the tank has a 1” male NPTM (national pipe thread straight mechanical vs. male NPT which is tapered). Code usually requires male pvc to be connected to female if using brass so, for this tank place a female-female coupling to the tank then continue with pvc to pump/house. **Q: why does the tank runs when there's not water running or leaks?** A: not understanding, is your pump running when u are not using it? Did you adjust the PSI of the tank with the recommended setting from your pump before using it? **Q: I have 11 water faucets, toilets etc. what size pressure tank should i have with a 1/2 or 3/4 horse shallow well pump?** A: The 'rule of thumb' is to count all inside and outside faucets/toilets/washers/etc and time the number by three then use a tank with the next larger capacity in gallons. So, in your case, 11water sources x3 = 33 so you would want at least a 35gal tank with 40gal being the 'standard' size. So, answer is you want a 40gal pre-charged tank. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pump bolts right on… *by R***S on October 17, 2025* Good price, works great!! ### ⭐⭐⭐⭐⭐ Water tank *by J***O on October 17, 2025* Work good for me, mounted right up. Would buy again. ### ⭐⭐⭐⭐⭐ Great for a small house with a modest jet pump *by J***R on October 21, 2019* This was a replacement for a smaller tank which failed. I had made a series of improvements to the rainwater catchment system at our small rural house, and the 5.5 gallon pressure tank was just too small for even a 1/2 hp shallow well pump. When the old tank finally got waterlogged I followed the standard advice of counting water outlets and multiplying by 3 to find out how many gallons the tank should be. Installed this over the weekend and it is a vast improvement. It took the pump about 30 seconds or so to fill this tank the first time, and now the pump runs properly without cycling on and off. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/16512161-waterworker-ht-14hb-water-worker-horizontal-pre-charged-well-tank](https://www.desertcart.sg/products/16512161-waterworker-ht-14hb-water-worker-horizontal-pre-charged-well-tank) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-22*
