To correct problems with the water valve on the float, first check for leaks. This is done by lifting the float stem up to the shut off. If water still keeps rising, then check the 0-ring at the bottom and all float fittings. To do this, turn the shut off valve (which is a small stainless steel rod at top of unit) one half turn. This will shut off unit. Reach down and grab the float assembly and lift it out. When problem is fixed, lower the assembly back down and insert into the pitless adapter. You can do this when the unit is empty or full of water. Just feel for brass adapter at bottom.
CAUTION: To prevent ice crystals from forming in the float area – we recommend you add one gallon of mineral oil.
Optional frost lids are available for drinking bowls when you will not be using the Thermosink Energy Free Livestock Watering Systems for extended periods of time. Thermosink can be winterized. To do this, first shut the water off by turning stainless steel rod 1/2 turn at top of unit. Open center lid and simply pull float unit out. Next, remove as much water as possible out of unit. Put center lid back on and optional side lids if you have purchased them. Your unit is now winterized. To restart the unit at any time, just slide float assembly back and turn water on.

Shut off valve
Remember to open & close the “shut off valve” before and after installation of brass fitting (prior to burying in the ground)
It is not necessary to use concrete around your waterer but if you choose to do so the top of the Thermosink must then be set at 26 inches above the ground.
When attaching water line to pitless adapter, do not use rigid pipe. Use flexible pipe only. This is important to prevent pressure and stress on the pipe which can render your Thermosink inoperable.
