How does oil filter contains a check valve works?

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.


Do you know what the problem might be if a swimming pool drains when the filter is on?

Backwash valve is leaking by. More than likely it is a bad oring inside the valve. Or it was not place back into recirc mode completely. or you may have a leak on the return side of the filter. That includes all the plumbing from the filter or heater to the pool. The back wash valve may be obvious if the waste line ends close by. The back wash valve should be placed in the "filter" mode not the "recirculation" mode. K


Where should the setting be on a drain valve for an inground pool?

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

Where is the AC filter located on a 2000 Lincoln LS?

If you mean the cabin air filter, its under the hood, back up against the windshield on the passenger side. Its under a plastic cover - you have to remove a few plastic fasteners by depressing their centers and then pulling them out. Filter slides out. To reinstall fasteners first pull their centers out (above flush) and then, after they are inserted, push in the centers to original flush level.

The sand filter has high pressure after only 20 minutes of run time?

This could possibly be that you are not running the back wash long enough or that there is a malfunction internally in the filter b/w valve. What brand filter? Ken
