This float valve will allow you to control the water level of your tank or reservoir with no maintenance. They can be mounted vertically or horizontally. Each one comes with a mounting nut and rubber seal. Also available with a 1⁄2” barbed fitting or 3/8” quick connect fitting. The unique thing about these is the quick connect fittings do not thread on. Meaning you can remove them and use any type of fitting, such as a ‘T’, elbow, or reducer!
