If you look at the pipe that is going into the filter pump you will notice that it has a tee that is peceeded by two or three pipes comming up from the ground. Those will be from the skimmer, main drain, and if you have one from the cleaner. If you observe the flow of water in the skimmer then change the valve so there is no more water flowing that will be the one going to the main drain or cleaner. Repeat the process to eliminate which one is the cleaner. Which ever one is left is the main drain.
If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
The bypass valve in an oil filter allows the oil to bypass the filter if the filter becomes clogged. Some filters also have an anti-drain back valve when the filter is mounted in such a way as the oil could drain out of the filter. This valve prevents the oil from running back into the engine out of the filter which would cause the engine to be started with an empty filter every time.
To drain water from a Duramax diesel engine, locate the fuel filter water drain valve, typically found at the bottom of the fuel filter assembly. With the engine off, place a container underneath the valve, then open it to allow any accumulated water and fuel to drain out. After draining, close the valve securely and check the fuel system for any additional water contamination. Finally, ensure to replace the fuel filter if necessary and check for proper operation.
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. Ken
If it like mine, 7.3 in a 350, there is a fuel filter located on the firewall side of the engine. There is a lever on it that opens a valve on the bottom. This will let the water that has collected in the filter to drain out. Put a pan under where the filter is and let the filter drain until you start to smell the fuel and then close the valve. I recommend doing this when the engine is cool. I think mine has a red lever that opens the valve. Hope this helps.
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
A little oil will drop into the cup when you remove the used filter. There is a black drain valve under the oil filter cup. You can remove the drain valve cover and let the small amount of oil drain into a cup. Wipe the cup clean before you install the new filter.
The Water Fuel Separator is located in the V of the Engine. You can remove the decorative cover over the water fuel separator. as you are facing the engine on the bottom back left side is the valve. slide it to the right Open the hood. Place an appropriate container under the filter drain under the vehicle. Locate the fuel filter drain valve. If necessary, remove the engine appearance cover. Open fuel filter drain valve by turning clockwise. Allow to drain for approximately 25 seconds or until clean fuel is observed. Close filter drain valve by turning counterclockwise until firmly seated. Verify that the fuel filter drain valve is closed. If removed, install the engine appearance cover. Close the hood and remove the container from under the vehicle. Restart the engine and check WATER IN FUEL indicator light. The light should not glow. If it continues to glow, have fuel system checked and repaired
The fuel filter is on the very top center of the motor, under a plastic cover. It has a drain valve that is used in filter replacement. The valve might have been bumped slightly to the drain position or the valve seal might be bad.
Need more specific info A multi valve pool filter is a common configuration of valve and filter for a swimming pool system. The piping into and out of the filter is attached to a multivale. A multivalve has has several positions. One type of multi valve has six positions: backwash, waste, filter, closed, rinse and recirculate. (These valve positions are used on a DE filter. A sand filter may be different.) Use the filter setting in the nromal operation of your pool. This setting receives water from the pump and directs it to the dirty side of the filter media and then receives weater from the clean side and directs it to the pool. Use the Backwash setting to flush the DE from the filter and to a drain. Use the waste setting to flush water directly from the pump to the drain. The closed position is, well, closed. Rinse? Recirculate?
