Trough-O-Matic Float Valve

Highly recommend. The valve i had in the fountain has never worked so had to be monitored manually. The problem was the water pressure was keeping the valve open. The design of your float is not influence by the water pressure from the source so allows the float to close the valve as designed. I had to convert from standard water hose connection down to a 1/4 inch copper tubing but was able to purchase what I needed at the local hardware store.

The Trough-O-Matic Float Valve work great. I often would turn on water and start doing something else and then remember the water hours later. These work as well as more expensive models that I have on larger stock tanks. The only negative I found is the hose connector is, without purchasing a 90 degree adaptor, on top of the valve and requires the hose to screw vertically down into the valve. This caused my hoses to kink. So, I was forced to purchase 90 degree hose thread elbows, at $6 a piece, so that the hoses connected parallel to to the ground.

Durability: 4

I have used these floats in my 3 horses' buckets for almost 25 years, they are dependable and amazingly durable. I love that I know that my horses are never without water. I live in florida, I guess they might have problems in persistent subfreezing weather, but they have been wonderful for me.

We have bought many of these over the years. They stop working and the water starts overflowing. The float seems to get stuck. I wrote to the company for advice to prevent the problem and got no response. Went back to water tubs.
