WTA Submerged Valve

Keep every tank full. No floats for animals to break.

The valve sits under the water and controls the level using the water’s own pressure. Install it once, set the level, and stop checking tanks.

Why submerged?

Floats break. Underwater valves don’t get in the way.

Livestock push, chew and step on anything that sits at the surface. Moving the valve under the water fixes the problem at its source.

Traditional float valve Problem

LEAK!
  • Float sits at the surface, right where animals drink
  • Arms bend, floats crack, tanks overflow or run dry
  • Constant checking and replacement

  • No floats, arms or cables to wear out
How it works

The water itself tells the valve when to stop

Press play and watch one full cycle, or take control: let the animals drink and turn the adjustment knob to change the level.

Valve open
SET LEVEL ¾” water supply · shut-off valve recommended Adjustment knob Water outlets
  1. 1
    Low level → valve openWith little water above it, the valve stays open and the supply water fills the tank.
  2. 2
    Level rises, pressure buildsAs the tank fills, the water pressure on the valve increases. The valve senses it and starts to close.
  3. 3
    Set level reached → closesAt the level you set with the knob, the valve shuts off by itself. No float, no arm.
  4. 4
    Animals drink → reopensAs the level drops, the pressure falls and the valve opens again to refill the tank automatically.
Water pressure on valve
Water flow in

Turning the knob changes how much water pressure is needed to close the valve, which moves the full level by about ±1″.

The valve

Few parts. Nothing exposed.

Every moving part stays sealed inside a rugged body below the water line, with nothing on the surface for animals to reach.

Installation

Install it in 4 steps, on the bottom or the side

All you need is a 1¾” hole in the tank wall and a ¾” water supply.

  1. STEP 1Drill a 1¾” holeBottom or side of the trough. The surface around the hole must be clean and smooth for a tight seal.
  2. STEP 2Insert the valve from insideThe sealing O-ring goes on the inner side of the trough.
  3. STEP 3Tighten the fixing flangeThread the flange from the outside until the O-ring seals.
  4. STEP 4Connect the ¾” supply and set the levelStart with the knob at a small gap (about 1/16″ of travel) and adjust gradually until you reach the level you want.
Keep the vent hole clear. The valve needs it to work properly.
Use clean water. Add a filter or strainer if the supply carries debris.
Add a shut-off valve on the incoming line for easy maintenance.

FAQ

Questions ranchers ask

How does it know when to stop without a float?

The valve responds to the water pressure in the tank. When the water reaches the level you set, it closes by itself. When animals drink and the level drops, it opens again.

Can animals damage it?

It’s installed below the water surface, out of reach, with no float or arm sticking out. That’s the main reason it lasts longer than float valves.

What size tank or trough does it work with?

Any trough or tank where you can make a 1¾” hole in the bottom or side wall and connect a ¾” water supply with 4 to 100 psi.

How do I adjust the water level?

Start with the actuator knob at a small gap (about 1/16″ of travel), then make small, successive adjustments until the tank fills to the level you want. The adjustment range is about ±1″.

What maintenance does it need?

Keep the vent hole clear and use clean water (add a filter or pipe strainer if needed). A shut-off valve on the supply line makes service easy.

Install once. Stop checking tanks.
