The Water Worker 20-Gallon Horizontal Pressurized Well Tank is pre-charged and designed to maintain its air charge for years to provide easy upkeep. The tank utilizes a thick diaphragm to keep water separate from pre-charged air and to help reduce air loss. This tank also features a steel shell to support the water weight, a polypropylene liner to help prevent taste or odor from being absorbed into the water and deep-drawn steel construction for durability.

  • The Horizontal design fits into tight spaces with very little head room
  • 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
  • Stainless-steel waterway lining has no plastic to cross-thread, strip or crack
  • Constructed of deep-drawn steel for durability
  • Sizing - Count the number of water fixtures in and outside the home and multiply that # by 3. Fixtures include faucets, spickets, shower heads, dish washer, washing machine, etc. For hot tubs and sprinkler systems add 1 to 2 fixtures for each. There are no disadvantages to having a larger well tank
  • 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 gallons of total volume; plain or galvanized tank equivalent of 42 gallons
  • Pre-charged to 38 psig; 100 psig maximum working pressure
  • Maintains air charge for years to provide easy upkeep
  • 1 in. NPTM system connection

Rated 4.3 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Tank was well made, not difficult to install I installed the tank using 1 inch pvc. The old tank was 35 + years old, filled with crude, I should have changed the old tank years ago. April 14, 2015
Rated 5.0 out of 5.0 by Great Item, easy to install and works well! The tank had easy to follow instructions and was a breeze to install. The metal bracket to mount the pump upon was a desirable feature that influenced my choice of this item. It works very well with a shorter cycle time than my previous tank. A follow up question to the manufacturer was professional and answered all my questions. April 16, 2013
Rated 4.0 out of 5.0 by Replacement tank The water tank was a different brand than my original, but was able to install with no changes to the plumbing fittings. February 23, 2015
Rated 5.0 out of 5.0 by Perfect fit Just the item I needed to fix my water pressure problem. Only took 20 minutes to change out. Old tank was leaking due to tiny holes caused by rust. Should get many years of use from new tank. December 22, 2014

Rated 1.0 out of 5.0 by Product was defective out of the box. The product was defective out of the box. I checked the air pressure before installation and it was at 0 psi. I tried filling it and could hear the bladder leaking. I had already removed my old tank so had to go out and find another one. I bought a different brand and had no issues with it. May 5, 2015
Rated 4.0 out of 5.0 by great tank for the price. the tank legs are its weak point,The spot welds are not the greatest. the tank does exactactly what its supposed to do hold water . Had to let a little air out of the tank to match the pump pressure regulator no big deal . well worth the price and it came to the house on time. May 5, 2015
