WaterWorker HT20HB Water Worker Ht-20Hb Horizontal Pre-Charged Well Tank, 20 Gal, 1 in Mnpt, 100 Psi, Steel, 20 Gallon Water Worker

Water worker well tank, horizontal pre-charged, series: ht-20hb, 20 gal capacity, 29 in diameter, 16 in height, 1 in connection, MNPT connection, steel, 100 psi, 200 deg F, nsf approved, 42 gal equivalency, for residential. Polypropylene-lined steel supports water weight to ensure water never sits in loose-fitting vinyl or rubber bags that can fold, crease and wear. Liner does not require scheduled replacements for long-lasting use formed liner fits the steel shell for added durability nsf certified. This pre-charged water tank is designed to maintain its air charge for years for easy upkeep. The tank uses a thick diaphragm to keep water separate from pre-charged air and to help reduce air loss. The tank’s steel shell with deep-drawn construction helps support water weight, while its polypropylene line helps prevent air and odors from being absorbed into the water.Pre-charged tanks are rated to compare with equivalent-size conventional (standard) tanks in terms of water drawdown between pump cycles. The ACTUAL physical size of a pre-charged tank is much less and allows space savings up to 50% when comparing drawdown and size to that of a conventional tank. Economy is achieved with the smaller size of pre-charged tanks compared to similar water delivery and size of conventional tanks. This tank has a rated size of 42 gallons; the ACTUAL tank capacity is 20 gallons. Max. Psi: 100, dimensions D x h (in.): 30 x 15, discharge port (in.): 1, Max. Capacity (gal.): 20, includes: tank, material: steel, polypropylene.

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.

• Designed to meet the requirements of, and are listed by the National Sanitation Foundation (NSF) under ANSI/NSF Std 62
• 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
