3/8" Brass Water Float Valve — 125 PSI Pool & Tank Level Controller

Product description

Durable brass construction: The core components are machined from heavy-duty brass to resist corrosion and hold up in pool and tank environments. The valve assembly uses metal body parts for longevity where plastic valves often fail.

What’s included: The package contains the 3/8" threaded float valve assembly, a molded float, an adjustable rod with wingnut, and the packing/seal components needed for installation. The unit is ready to attach to standard 3/8" fittings.

Compact design for in-ground pools: The valve's relatively small footprint lets it be mounted in tight spaces around pool equipment and skimmer boxes without getting in the way of other plumbing.

Adjustable float level: An adjustable screw/rod allows you to set the water cutoff point precisely. Raise or lower the float on the rod to determine the fill height and prevent overfill or underfill.

Easy wingnut adjustment: A large wingnut secures the float position and makes tweaks simple without tools. This user-friendly adjustment helps fine-tune operation after initial installation.

Flow and pressure compatibility: Rated for a flow capacity of about 2.25 GPM and tested up to 125 PSI, the valve provides steady water regulation for automatic fill systems, garden fountains, tanks and similar applications.

Pros

  • Solid brass body resists corrosion
  • Simple tool-free float adjustment
  • Fits compact in-ground pool setups

Cons

  • Some units may need minor tuning to stop drips
  • Requires compatible 3/8" plumbing
  • Plastic float may wear before brass parts

VerdictA robust 3/8" brass float valve that delivers dependable water-level control for pools, tanks and fountains. The solid brass body and sizable float make it suitable for in-ground pool autofill and similar applications, while the wingnut adjustment and threaded rod let you fine-tune shutoff height. Most users find the valve stops reliably and offers straightforward installation; a minority report o

Reviews

  1. Cecil McBride 4/5

    Needed extra fittings but works

    Required several adapter pieces to tie into my lines, but once connected it performs reliably.

  2. BWM 5/5

    Perfect fit and operation

    Installed easily and functions exactly as expected.

  3. Mike 5/5

    Replaced leaking plastic valve

    Switched from a plastic float that never closed fully to this brass unit for my pool autofill. It shuts off cleanly when full; hoping it holds up over time.

  4. xochitl 5/5

    Handy for garden fountain

    Mounted on a yard fountain and it maintains water level without issues.

  5. Teezal 1/5

    Occasional leak until adjusted

    Had to jiggle and tweak the float a few times; it dripped when the plunger was down until I re-set it.

  6. GW 5/5

    Good replacement option

    Operates smoothly and the adjustments give a nice level of control.

  7. Richard A. Rose 5/5

    Solidly built and stopped my leak

    Good heavy brass build with a sizable float — replaced my old unit and it immediately cured the pool filler leak.
