About This Product

This Water Worker 20 Gal. Pressurized Well Tank is a direct-fit replacement for many installed well tank bases. It's highly durable with a deep-drawn steel construction and a polypropylene-lined shell. The shell supports the water weight and the liner separates the water from the shell so there is no taste or odor. The thick diaphragm keeps water separate from pre-charged air to reduce air loss. This tank comes pre-charged and will maintain its charge for years for easy upkeep.


  • Designed as a direct-fit replacement for the majority of installed well tank bases
  • Constructed of deep-drawn steel for durability
  • Polypropylene-lined steel supports water weight to ensure water never sits in loose-fitting vinyl or rubber bags that can fold, crease and wear
  • NSF certified for clean safe drinking water
  • Polypropylene liner separates water from the steel shell to prevent taste or odor from being absorbed into the water, formed liner fits the steel shell for added durability
  • Sizing - count the number of water fixtures in and outside the home and multiply that # by three; fixtures include faucets, spickets, shower heads, dish washer, washing machine, etc. for hot tubs and sprinkler systems add one to two fixtures for each; there are no disadvantages to having a larger well tank as fewer pump cycles will extend pump life and save money on electricity
  • System connection: 1 in. NPTF, threaded malleable iron elbow with stainless steel insert; connection does not include plastic that can cross-thread or crack
  • Thick diaphragm keeps water separate from pre-charged air and helps to reduce air loss
  • Molded diaphragm offers an ideal fit, sits on top of the water and will not fold, crease or drag against the steel shell
  • 20 gal of total volume; plain or galvanized tank equivalent of 42 Gal.
  • Pre-charged to 38 psig; 100 psig maximum working pressure
  • Maintains air charge for years to provide easy upkeep
  • Two-part water-based paint system sprayed over a durable two-part epoxy primer provides corrosion resistance and safe paint covering
  • 1 in. NPTF system connection uses malleable iron for dependability
  • Well tanks are not be used in Reverse Osmosis systems
  • Well tanks are not be used for water expansion in thermal (water heater) or hydronic (boiler/solar) systems
  • Accessories shown in alternate image sold separately
  • Tank Size: 15 in. dia. x 32 in. H

        Q:I too am asking this question???? At the bottom of my 20 gallon pressure tank there seems to be a spring loaded valve just inside the welded nipple. What is that for? I'm not getting any water in the tank.

          Easy to install, and pre pressurized definitely helped out in the installation. Installation was in a well pit so it was a tight fit but with a smaller circumference then the original bladder tank this was the ideal option.

          Excellent value for the size and in stock at my nearby HD. Installed easily and I have it set up to run at 40-60 psi. Found it pressurized a little high at 43 psi, but easily adjusted. Working great at the one week point and hoping it will last long beyond it's 5 year warranty.

          Box says 5 year warranty, What a load of crap that is. Installed Tank in Dec. of 2021, still have receipt. Blew out in Jan of 24. Two years and 2 weeks it lasted. Previous tank lasted 21 years of course it wasn't WATER WORTHLESS! Book says to contact distributor (HOMEDEPOT) which was a waste of time. Contacted Manufacturer, another waste of time. Save time and money. Don't buy this junk!

            Waterworks 20 gallon pressure tank
            The pressure tank only lasted four years. The diaphragm went bad. I called Home Depot. They said they don’t back it up so to call the manufacture neither of them back it up. It’s a lot of work to plummet in and only have it last that long. I’ve had several in the past and they last at least 15 years the 20. So I would spend more money next time and get a better one.

              Most new steel water tanks are 18 Guage
              For 20 gallon units that is a shipping weight of about 33 LBS. Simple DIY installation to replace heavy duty 40 YO galvanized tank. Like aircraft you only get so many pressurization cycles before stress cracks develop near the welded hoop seam. I'm running two Water Worker tanks in tandem to increase diaphragm life and reduce the number of pressure cycles per day to just one or two now. Working perfectly with peak pressures near 50 PSI instead of 60. The Water Worker stainless steel connector will be important after five years. I reduced the pre-charge to 30 PSI for the lower working pressure. 34 second fill time with 1 HP pump. Home Depot does not provide a five year warranty so don't buy this expecting warranty replacement if you have a high pressure, short cycling system with over five fills a day.

                DO NOT BUY, DANGEROUS
                less than 1 year later, this pressure tank leaked from the elbow. the elbow is made with cheap steel, this is likely the case for all newer 2022 models. they cheaped out on the elbow, and it now is a dangerous situation as it can blow at any time.
                  Easy to install
                  My husband and I purchased our Water Worker 20 Gallon Pressurized Well Tank after our old one stopped working. My husband said it was easy to install, it only took him a couple hours to put in. So far, it works great and we're happy with it.

                    Lasted 3yrs - then flood
                    The tank looked nice when installed. 3.25yrs later a pinhole developed which began to flood the house. Fortunately, I noticed the same day and turned off well and valves limiting damage. I recommend checking tank daily after 3yrs of use. The well guy said this is a 3-5yr tank. The warranty is 1yr. The new tank cost double but has a 7yr warranty.

                      Rusty Water
                      I had one of these for 6 years so when it went out I got a new one,but this time I put a filter on before the tank and one after the tank. All this time i thought my well water was just rusty, full of iron. Well it is what is coming out of the tank that is rusty not my well. This makes me sick to know this and now either I use it till it goes or replace it with something better and be out 360 dollars.
