This Kerick MA052 float valve is a tank-mount style with an adjustable arm, and is made of PVC with 18-8 stainless steel hardware. The valve has a 0.093" orifice and its estimated rate of flow is 1.3 gallons per minute (gpm) at 40 pounds per square inch (psi) and 1.5 gpm at 60 psi. The valve inlet has 1/2" NPT male extended threads with a sealing washer and jam nut for mounting through a tank wall, and the valve outlet is free flowing. The valve is made of National Sanitation Foundation (NSF) approved PVC (polyvinyl chloride), its replaceable seals are made of TPE (thermoplastic elastomer) for durability and chemical resistance, and its hardware is made of 18-8 stainless steel for corrosion resistance. The valve has a 1.5" in diameter and 4" long polyethylene float attached to the adjustable shutoff lever arm. This float valve is suitable for use in a variety of applications, such as fountains and livestock water tanks.
Float valves use a rod and float ball attached to a valve shutoff lever to control flow in or out of a tank. The float ball rises or falls with the level of liquid in the tank, changing the angle of the valve shutoff lever. When the angle of the valve lever changes sufficiently, the valve opens or closes. Float valves are rated according to the volume of liquid that can flow through them at a particular pressure to ensure the tank can be refilled as quickly as it is emptied. The material that a float valve is constructed from must be suitable for the liquid in which it operates, which may be corrosive or at an extreme temperature. Float valves are used to automatically regulate the level of liquid within tanks in a variety of applications, such as fountains, livestock water tanks, cooling towers, and chemical manufacturing plants.
Kerick Valve manufactures fluid level control valves for industrial applications. The company, founded in 1994, is headquartered in Jacksonville, FL.

I gauged the valve orifice with a drill rod at 0.094 inch (3/32 inch) diameter, which accounts for the low flow rate specification. You may not want to fill a swimming pool with it from scratch, but for a typical backyard pool it will allow more than enough water to flow to compensate for evaporation loss. The float arm pivots on a stainless steel cotter pin, so it could easily be disassembled, should the need arise, although at the low cost of the assembly it may be more economical to replace it entirely. Depending on the placement of the valve, the float can be adjusted over a liquid level range of at least 4 inches, possibly as much as 6 inches, by loosening the stainless steel wing nut.
One of these valves was successfully used to maintain the water level in a neighbor's swimming pool last summer during a month-long absence. See the customer photo that I posted, showing the minimalist installation with a few pieces of PVC plastic plumbing, an ordinary brick and a garden hose. The only problem I encountered was the hose of the automatic pool sweep once getting hung up on the valve, keeping it open continuously. Because of the restricted flow, no flooding occurred by the time I discovered the problem the next day. If I use it next summer again, I'll mount the valve with some sort of bumper or "fence" around it to keep the pool sweep hose clear, and I'll replace the leaky plastic hose fitting with a sturdier brass fitting.
This float valve has eliminated all of that. With a quick trip to home depot to get some PVC fittings, I was able to hook it up to a garden hose to create an automatic pool filler that is set it and forget it. I was worried that my large pool (36,000 gallons) might be too much for the valve to keep up with in the middle of summer, but it works perfectly. This would be my first recommendation for anyone with a pool.
The problem I discovered is that the valve never completely shuts off, even when the arm is all the way up. You still get small drips into your water, which leans to overflowing. It's very slow, we didn't notice it at first because our dogs drank enough water to keep it from overflowing. We saw it getting higher in level. But then on cooler days, they drink less and it would reach the top. Finally emptied all the water and held the arm up. Drips.
BTW, there is another float valve out there that is flawless in design. Check out B01D0FYH46.
