Hmmm, do you possibly mean the back wash valve on the filter? This valve has many positions to choose from especially for sand filters. Filter, back wash, drain, drain to waste, filter bypass, closed. They are pretty much self explanatory. Normal position would be the "filter" position while the pump is running and the filter is working.
There should be a drain valve where you can hook up a hose and then open the valve to drain.
If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
it'a on the right side of the mower (setting on it) just above the front of the deck . there is a valve that you have to turn to drain the oil ,it came with a hose that hooks to the valve as to not make a big mess Hope this helps
No, not usually.
immediately above the stop valve
There should be a small valve at the bottom of the rad.
There should be a drain valve on the radiator on the bottom passengers side If not just undo the bottom radiator hose.
All the 6.5's have a water drain valve for the fuel filter. It is the brass valve that is mounted to the thermostat housing. Pull the drain line out of hiding and put in a container then start truck, then open valve, water should flow out. ... just what i was told sounds correct
It either goes into the ceiling undetected for a long time Or it can go down the over flow past the stopper and into the drain line depending on whom did the installation
Washing machines should be trapped.
It must be at bottom of the radiator, you should a valve responsible for drainage.
