Product Overview

The Water Worker 4 Gal. Pressurized Well Tank features durable deep-drawn steel construction and a polypropylene-lined steel shell that supports the water weight to ensure water never sits in loose-fitting vinyl or rubber bags that can fold, crease and wear. This pre-charged well tank offers a direct-fit replacement for the majority of installed well tank bases, and the tank is made to maintain its air charge for years to provide 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
  • 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 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 as fewer pump cycles will extend pump life and save money on electricity
  • Stainless-steel waterway lining has no plastic to cross-thread, strip 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
  • 4.4 Gal. of total volume; plain or galvanized tank equivalent of 12 Gal.
  • Pre-charged to 38 psig; 100 psig maximum working pressure
  • Maintains air charge for years to provide easy upkeep
  • 2-part water-based paint system sprayed over a durable 2-part epoxy primer provides corrosion resistance and safe paint covering
  • 3/4 in. NPTM system connection offers easy installation
  • 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

I HAVE A GRAVITY FEED TANK THAT SITS ON THE SECOND FLOOR AND the water flows down to a spigot and a couple sinks. where would i be able to hook this device up and how? wATER PUMPs via the well house pump (electric) upstairs to a 50 gal. tank and then back down to the sinks and spigots with low pressure. can i use both?
Asked by: cody
Assumption - your 50g tank is a holding tank you've elevated for at least a little pressure at your fixtures. To get some real pressure to your sinks & spigot you could add a pressure tank and a transfer pump from your holding tank. It would look something like this: well pumps to your 50g holding tank -> transfer pump & pressure switch -> check valve -> pressure tank w/tee, pressure gauge & pressure relief valve -> supply to the sinks & spigot. The transfer pump would fill the pressure tank as the gravity feed from your holding tank will not successfully fill your pressure tank. When you call for water at a fixture the water will be provided at the pressure you set your pressure tank to (i.e. 40 psi). As the water is used from the pressure tank and the pressure tank empties the pressure in the tank will drop. The pressure switch on your transfer pump will read this drop and start the transfer pump up to move water from your holding tank to the pressure tank (and also continue to provide water at the fixture you are using at pressure until you turn the water off there). After the demand for water at your fixture is stopped the pump will continue to run until the pressure tank fills to the "cut out" pressure on your pressure switch (i.e. 50psi on a 30/50 pressure switch) at which point the pump turns off until the next time it needs to refill the pressure tank. Now if you pumped from your well directly to a pressure tank, you could place the pressure tank wherever you wanted (upstairs or downstairs) and you wouldn't need a transfer pump, nor the holding tank. Get a big pressure tank (the actual water capacity not the "equivalent" so that your well pump runs for awhile when it is called and doesn't short cycle) not the 4g one your question was attached to.

Can this tank be used in a Reverse Osmosis System?

Asked by: Buck
I do not see anywhere in the specifications that this tank is certified for drinking water. I would not use it as an RO tank. There are many other certified RO tanks designed for the purpose that you can get.

Rated 5 out of 5 by from Nice pressure tank I needed a compact water pressure tank for my fifth wheel trailer and this tank fit the bill. It was what I expected and installed easily. Now my water pump cycles less and my water pressure is more steady. It took over a week to get to California from the east coast, so order early! I hope it lasts a long time, we will see.
