Little Giant Trough-O-Matic Float Valve, Metal is rated 3.7 out of 5 by 6.
Rated 3 out of 5 by from Easy Assembly but leaks Purchased two, both have constant drips. Not sure if it’s design, lack of a quality gasket, or what. But wastes a lot of water. I’ve lowered he water pressure so it slowly fills, but it still leaks.

Rated 1 out of 5 by from Warning I have used these for years. I just bought a new one to replace a leaking valve (which happens too often). When I went to install the new one, I found the new one would not mount in the old location. Mounting brackets in new location. I had to make new holes in the mounting plate on the stock tank in freezing rain today. Not a happy camper. I would like to meet the engineer (?) who made this brilliant change. One star is too good!!! I will look for alternates next time.

Rated 3 out of 5 by from Don't let it freeze! I use this float to keep my big dogs watered. It works very well, but with one caveat: You can't let it freeze. At least not if you want to use it again. The weakness is in the little plastic orifice/valve opening the water flows through. If that orifice has ANY water in it whatsoever and the temperature goes below freezing, the plastic will break, which renders the shut-off valve inoperable. This flaw was demonstrated dramatically for me this morning. My original Little Giant float had failed early this winter for the reason above. I replaced the unit last week. Last night we had what will likely be the last hard freeze of the year here. In anticipation, yesterday I emptied the water bucket and turned off the water supply to the float. It didn't matter -- this morning I found the end of the water orifice, filled with ice, broken off down in the bottom of the bucket. I'll replace the float again because it works just great when the weather is warm. It's just not suitable for winter use or cold climates. Even using a water bucket heater wouldn't solve the problem. Overall, it's a bad specification for the engineering plastic used to mold the valve.

are the adjustable brackets available in longer lengths to allow less water depth before shut-off?

Asked by: Rpjr
We do not have brackets in the longer length. We have the standard L-shape bracket (T804) and the C-shape bracket (T805.

On the float what would be the max amount of flow that could go through it if you have the standard 50 pounds pressure at your house or farm

Asked by: Loek
This flows up to 245 gallons per hour and operates at pressure between 20 and 50 PSI.
